B25 Video 13.Restoring to taxi condition the Airworthy

Añadido: 2026-05-07

[00:00:13]Hi, video 13 of the restoration of the B25 Mitchell bomber at the Lincolnshire Aviation Heritage Center at East Kirby.

[00:00:22]This will be restored first to taxi conditions, then be made airworthy. They require the B-25 for taxing when Lancaster NX611 just Jane comes offline in 2028 29 to complete the task of making her airworthy.

[00:00:42]This video covers work in July and August 2025.

[00:00:48]The team continues removing the two engines hydraulic and fuel pumps. These will be sent away for inspection, repair or renewed.

[00:00:59]The ones fitted back will be airworthy.

[00:01:01]They will not be fitted back to these engines, but two reconditioned airworthy engines which are being serviced in the USA.

[00:01:12]These are the pilot and co-pilot adjustable seat runners, paintstripped, inspected, repainted, and ready for assembly in the cockpit. These will be fitted first. Plywood laid either side to protect the floor paintwork while fitting out the cockpit.

[00:01:38]Josh is outside welding making a rear two large stand for the B25.

[00:01:46]>> Hi Josh.

[00:01:48]>> What are you making now?

[00:01:50]Um just reinforcing sacriot. It's the one that's usually under the tail of the B25.

[00:01:57]>> Oh yeah. Yeah.

[00:01:58]>> I think we've got a um original drawing in there. I'll show you in a minute.

[00:02:02]It's got um like a cradle on top basically.

[00:02:06]>> Yeah.

[00:02:06]>> With leather like >> are they for as well?

[00:02:10]>> Yeah, these are >> Oh, I see strengthen it.

[00:02:18]So that one will get welded in there.

[00:02:20]>> Yeah.

[00:02:20]>> And then he will >> Yeah.

[00:02:22]>> Weld on there.

[00:02:24]>> Morning Neville.

[00:02:25]>> Good morning, sir.

[00:02:26]>> How are you?

[00:02:27]>> Fine, thanks.

[00:02:27]>> We are um removing pumps. If you'd like to have a look, >> moving the pumps starboard side.

[00:02:34]It's the one we showed you before with a little bit little bit of wear in it. But I've kept that together so we don't all the all the um all these are inside in there. This part here as well. Just >> getting on here just so I can put it in a bag and put it on the shelf.

[00:02:53]>> Yeah. Will you be able to get it serviced in England or will it >> to be honest? I won't to be fair not a lot goes wrong with oil pumps. So you only you check the lash. I mean the lash is okay. But this is quite good cuz the adjustable oil pressure. So you can actually >> even if the oil pressure is down a little bit, you can actually screw them in >> and you can alter the oil pressurees done on here. So I shouldn't think the tolerances are that great in the pump >> if you got that, you know, you can actually play about with these to get your returns and flows. So you actually get your oil pressure 85, >> which is quite a good idea, right?

[00:03:29]>> Yeah.

[00:03:30]>> Which I presume that's What's this? A trampoline fraction then?

[00:03:38]>> Yeah, it's it's >> technically that's not what that's what it looks like, but it's it's to hold the >> stansion the back of the B25.

[00:03:47]>> Oh, see there's what it's made of the >> where the bulge >> the bulge at the back sits in there.

[00:03:57]>> So, he's nearly he's just about ready to put it back to >> who's done the bit of sewing. I don't know who's done the sewing, but Josh has done unless he's got someone to do it for him. He's he's done those this morning. Got the rings and everything on it.

[00:04:08]>> I don't know who's actually done the sewing for him.

[00:04:10]>> Yeah.

[00:04:11]>> Unless he's Unless he can sew as well.

[00:04:12]He's he's a bit of a jack of all trades, isn't he?

[00:04:14]>> Yeah. So, that will be fit onto here then, will it?

[00:04:17]>> Yeah. Go on top of that. Yeah.

[00:04:25]See goes in >> pin goes in there above that ring.

[00:04:31]>> Oh, I see. Adjust it there.

[00:04:33]>> I see. You can adjust the ring and move the pin up. Yeah.

[00:04:37]>> Yeah.

[00:04:38]>> And then the basket that basket goes on there will go on there. It's only really if you be an octopus.

[00:04:59]>> Get my right arm behind me.

[00:05:16]and rechecked. See, that's part of the rigging. These might have been set up to to match the what the rigging says it should be. So, >> so the what is this? What what part is this?

[00:05:26]>> So, this is the auxiliary quadrant. So, you got you got a main quadrant which car taken apart on the bench there.

[00:05:32]>> Yeah.

[00:05:32]>> With all the levers. Yeah. And this is the auxiliary one. So this is the um for the for the um carburetor and the and the and the supercharger.

[00:05:41]>> Yeah.

[00:05:42]>> So the supercharger levers.

[00:05:43]>> So the these will be at some point when when it's all together rigged so that when it's on zero the cable right when it's on maximum the cable right. So >> so you can't you can't really rig it any other way than than air worthy.

[00:05:56]>> No.

[00:05:57]>> Obviously the key >> the key element is the cables.

[00:06:01]>> Make sure the cables are are worthy. So they'll all get replaced.

[00:06:05]>> Um but actually what this side this this will be >> this will be air worthy >> if if that answ your question. So yeah.

[00:06:14]>> Oh good.

[00:06:15]>> Yeah. Everything everything with that because there's no point doing it doing it twice.

[00:06:18]>> No. No.

[00:06:20]>> Um so yeah. So that's the auxiliary quadrant that that's just the uh that's just the control box where all the obviously all the all the cables.

[00:06:28]>> Yeah.

[00:06:28]>> Um go around but but invisible to the air crew. And then the main quadrant is what what's on the bench over there.

[00:06:36]This is all the stuff I took apart.

[00:06:38]We're just waiting for the >> Oh, that's right. Yeah.

[00:06:40]>> Waiting with the fasteners to come back.

[00:06:42]Oh, >> that's what you're waiting for, is it?

[00:06:44]>> Yeah. So, this is this is the throttle, the propeller feathering.

[00:06:48]>> Um, and the the magneto.

[00:06:50]>> Yeah, cuz you assembled it once, haven't you? Making sure everything >> make sure it's okay. And I've disassembled it. So, when we when we're ready, we can do it. Um, we can get a stage check done. So somebody else will independent will come in and make sure everything is is as it should be and complete.

[00:07:05]>> I will then reassemble it and again at some point when it is installed it will then get properly rig rigged and checked out.

[00:07:12]>> We can then start to rebuild the cockpit and um and reassemble the the quadrants as well. So >> So the cockpit is still empty. Did you put you haven't put those fasteners on for the seats yet, have you?

[00:07:26]>> No, they're they're still on the the bench over there. again that that's some yeah part of the factors we're waiting for. So >> yeah.

[00:07:32]>> Yeah.

[00:07:32]>> Uh we had these um the the dock remade.

[00:07:36]These these are what stop the seat going too far forward. So we've had all these re remade.

[00:07:41]>> Yeah.

[00:07:42]>> Out of sort of packs of material.

[00:07:43]>> Yeah.

[00:07:44]>> Um to to the drawing. Um they'll get all reinstalled. But you have to fit those first before you then fit the uh fit the fit the tracks in in the in the Yeah. They're they're all >> Did you have to do any to the track? So, they're >> No, no, just just just a good clean. A good clean and just a bit bit of pain just just to keep them protected.

[00:08:04]>> Yeah.

[00:08:05]>> Um >> we were we were two two springs short.

[00:08:08]Now, these these are the springs that go in the side of the seat. So, when you pull the lever, it allows you to take the weight off and the seat will rise.

[00:08:16]Um so, we're having two of these two of these manufactured by from Skgner Springs for all. So they should be here week after next.

[00:08:27]>> Get get the seats complete then >> and these won't go in until >> towards the end.

[00:08:43]>> The main the main longer ones that run through the aircraft give the to give it that core stability. They're held in place by by fittings. It's a fitting center. You could put a little bit of these L-shaped. Um the these would all been manufactured by being extruded. So So you spit that that shape. So you have a long long extrusion. Yeah.

[00:09:03]>> Cut them and then machine them to to that shape.

[00:09:06]>> Yeah.

[00:09:06]>> Um and we we've took we've found one >> that's got evidence of um interranular corrosion, exfoliation.

[00:09:13]>> So really really nasty stuff. So we couldn't >> we don't think we'll be able to repair this at all. So we'd have to get this replaced. Yeah. So clearly we're not going to find anybody who would make us an extrusion extrusion to that shape what for one bracket would have. So so we have to then look at >> getting it machined from a solid blet of aluminium.

[00:09:33]>> Um so then obly the question making sure that it sits the right material with the right properties an extruded component is different.

[00:09:40]>> What is this for?

[00:09:42]>> This is a bracket that holds the um the longer on the main longer ons. 32 of these alto together.

[00:09:49]>> Yes.

[00:09:50]>> Um and and >> how many do you want?

[00:09:54]>> One.

[00:09:56]>> Just this way.

[00:09:57]>> Couldn't you? Um >> and and they are different different shapes.

[00:10:01]>> Oh.

[00:10:01]>> Depending on where where they fit. This is different to this one.

[00:10:04]>> Oh yeah. I was going to say most likely.

[00:10:07]>> So we have to get the material agreed and then the manufacturing process agreed. So to get one machined from a solid blet >> as opposed to extruded sort of that's just something else that we need to >> Would you forge it?

[00:10:18]>> Um it'll be a real one.

[00:10:20]>> No it'll be a real one. No. Um >> no but then I >> I know stamp stamp forged.

[00:10:28]>> Well again it's it's making the tooling for it.

[00:10:31]>> Yeah you know >> just for one. Yeah >> machining it is far easier because you don't need special tool. You just need the machining tools to to to come out with and >> other people have done it. We've seen evidence of other people who've had these machined.

[00:10:43]>> Yeah.

[00:10:43]>> But obviously we need to make, you know, we to get the right >> material cuz I think originally the these were like a um a zinc alloy, >> aluminium and zinc mix >> whereas the modern equivalent is more of a is a aluminium copper mix >> which is slightly easier to machine. So >> but they are very very similar properties.

[00:11:00]>> Do they take a lot of strain or weight?

[00:11:03]Very much. Um well it's the main the main to torsional um resistance is it comes from the longer run that's where it gets his main core strength from >> um so there is there is a bit of you know there is a fair bit of force force go going through certainly going through the longer ones and obviously the these then >> no go all the way down the fuselage they >> do they're not not complete they are sectioned so there's one that goes runs the whole length of the bumper I can show you in the >> so this This is one of the uh one of the the lower longer ones. It runs all the way from >> set two station 224 to three three or four at the back and then behind holding these in place. You can see where the brackets are.

[00:11:46]>> There's one there, >> one there that were taken off cuz it's corroded. Yeah.

[00:11:49]>> And then two more underneath.

[00:11:50]>> So they're clamped top and bottom four.

[00:11:53]>> Yeah.

[00:11:54]>> So there's four there and obviously four four of this end as well.

[00:12:02]Then there's there's similar long runs straight above us inside the aircraft.

[00:12:07]And then there's longer versions starting here which then go all the way back to back to the tail.

[00:12:14]>> So these are extruded are they?

[00:12:16]>> These are extruded section. Oh yeah section aren't they?

[00:12:20]>> Yeah they are. And these are the other brackets four four. So that that that's kind of where they where they come from.

[00:12:27]No, >> this one here. Is it what's gone?

[00:12:30]>> It is. Yeah. Yeah. Yeah.

[00:12:32]>> That's a shame, isn't it? Just one.

[00:12:35]>> It is. But >> And this was the rather one than than 32.

[00:12:40]>> Yeah. Well, that's true. And especially if they're all different sizes.

[00:12:43]>> They are. Yes. Yeah, they are.

[00:12:46]>> The long girons inside the Bombay. Andy commented that they were excusions, but when editing this video, I noticed one was fabricated.

[00:12:57]>> I had a word with aid about this as Andy wasn't present when I visited these.

[00:13:03]>> Yeah. And he's put a new or he's put the old bracket back on. We said those were extrusions, but when I looked on the You can see they're made out of >> Look here.

[00:13:16]>> That's not That's not fabricated. That one is it?

[00:13:19]>> Yeah.

[00:13:20]>> So that's extruded.

[00:13:21]>> That's extruded.

[00:13:23]>> I see. Yeah.

[00:13:26]Yeah. That one is. Yeah.

[00:13:27]>> It's got a double underneath that one.

[00:13:29]>> Doubler. Is it >> under here? Yeah. Look under here. You got the extruder coming down. It's got a little It's got another strip. It's got a strip put over it. Unless that's machined in, but I don't think it is.

[00:13:41]>> Yeah. So, it changes, doesn't it? It changes from extruded.

[00:13:44]>> Yeah.

[00:13:45]>> To um to fabricated there. I don't know whether in the back it goes back to extruded or whether it stays fabricated or stitching.

[00:13:56]>> Who did the stitching?

[00:13:58]>> Uh it's John's wife.

[00:13:59]>> Who?

[00:14:00]>> John's misses.

[00:14:01]>> Oh, did you? Oh, that was good then.

[00:14:03]>> Yeah, it >> Yeah.

[00:14:06]>> I'm not sure how don't think the poppers will take the whole weight of the tail if it comes down on it. But >> I think they'll pop loose. But >> yeah, >> still supports it. That's the main thing, isn't it?

[00:14:18]>> Wedge in there then. Wonder if they went.

[00:14:20]>> Yeah.

[00:14:21]>> In theory, it slows.

[00:14:23]>> Slows it down on his descent. Anyway, >> that's good job.

[00:14:30]>> Yeah.

[00:14:35]>> This is made of steel. It's to prevent the rear of the fuselage from damage if grounded when in motion or when badly balanced when static.

[00:14:46]what Josh was making last week.

[00:14:55]Paul's the only volunteer working on the B25 today. He's making foot guards which fit around the rugged pedal bearings in the cockpit. The original guards were made out of templated steel.

[00:15:09]Replacement will be made from aluminum.

[00:15:12]The opposite guard is in good condition and will not be replaced.

[00:15:19]>> Sits over this sort of area around there.

[00:15:24]>> Oh, does it? Yeah.

[00:15:25]>> Yeah. Stop like that.

[00:15:30]>> Stops the feet from bashing into it. But as you can guess, it's corroded away.

[00:15:38]>> This is what Paul's working on.

[00:15:44]Yes, that's good. Well done, Paul.

[00:15:46]>> Thank you very much, Neville. Thank you.

[00:15:49]>> Oh, ob ready ready for the air show.

[00:15:51]>> Oh, and so cleaning it up.

[00:15:55]>> Two weeks we spent taking all the um >> accessories off the engines for to get them all coral together. So, >> we've got them all off a starboard engine now with all the racks all labeled up. Um so things like the um the oil pump, fuel pump, hydraulic pump, >> generators, magnetos, starters, all things like that. All things that we can send away in a Warner.

[00:16:16]>> Yeah.

[00:16:16]>> Get them refurbished, overhauled life in the US >> and then then get them back. So I've done all that for the starboard engine.

[00:16:23]>> Um but obviously with it being air show, we're now >> getting it all >> panled up again so we can take take her outside for the weekend for the air show.

[00:16:30]>> Yeah. Yeah.

[00:16:32]>> And then Terry Cherry is going to identifying some of the >> the bits that we'll go back in as part of the cockpit rebuild.

[00:16:39]>> Yeah.

[00:16:41]>> Flight deck. Flight deck.

[00:16:42]>> Flight deck.

[00:16:43]>> Fly deck.

[00:16:44]>> Cockpit test flight deck.

[00:16:45]>> Flight deck.

[00:16:46]>> In the book.

[00:16:47]>> What's the difference between a cockpit and a flight deck?

[00:16:50]>> Cockpit you climb into, flight deck. You walk into >> So, how is this progressing now? It's virtually stuck. Is it? We we're just waiting for what we want to do is get the now it's been painted. We don't want to try and damage the flight deck. So, but they come up a good idea. We've got some seat rails. When they get put back in again, we can then put flying on it.

[00:17:16]Yeah. The office. Yeah.

[00:17:18]>> Yeah.

[00:17:18]>> And they >> they've got that and all the gauges.

[00:17:22]What about the gauge? Are you having them cleaned up now?

[00:17:26]>> They'll all need to be tested for operation. Well, that those that on critical, they need to test it.

[00:17:32]>> Yeah.

[00:17:33]>> Make sure that they make sure they operate.

[00:17:35]>> Yeah.

[00:17:36]>> But all we're doing at the moment is clean them, but don't do any sort of work on them because >> that's could invalidate >> or make it worse, you know. So, >> yeah.

[00:17:47]>> Yeah. You need to be a little bit, you know, a little bit careful with them.

[00:17:50]>> Things like communications will source a modern communication solution, a modern radio to go in there and the same as you have done on Z. Yeah, >> that that side of it would have to source new and then and then in put the uh >> the um >> it go in there >> print modern radios.

[00:18:10]>> Have you seen we've seen a modern one?

[00:18:11]>> Yeah.

[00:18:13]We'll fit in the round one >> and that's included transponder and everything. Yeah.

[00:18:19]>> Yeah. What >> a new radio edition.

[00:18:22]>> Yeah.

[00:18:24]>> You end up with a little It's no bigger than that. Cuz obviously it's designed for like sets to fit in. So you could take an instrument out.

[00:18:31]>> Yeah.

[00:18:31]>> And it does all the stuff. It does all the radio, but you also need a transponder. But now with all this modern stuff, you you know, do you do you look at flight radar?

[00:18:40]>> No, I don't. No, I I used to, but I haven't done it.

[00:18:43]>> The information they get off that is off the transponder. Yeah.

[00:18:45]>> The score numbers. And it's all done in through this the smallest little thing where before it all be big, >> just a small little instrument.

[00:18:54]>> Yeah.

[00:18:55]>> Okay. Is there a square or a larger piece of material going in this left hand side?

[00:19:02]>> Well, here.

[00:19:03]>> Yeah, >> that's two instruments in there. That's that's your main gyro in.

[00:19:06]>> Well, I thought there was a big gap um aid with filling it in somewhere.

[00:19:12]>> That bit. Yeah, I couldn't see it.

[00:19:14]>> Yeah, that bit repaired invisible.

[00:19:19]Yeah, black. And also >> it strengthened because they done a bit of >> damage, >> as you can see here.

[00:19:28]>> Yeah.

[00:19:28]>> It's wasted down.

[00:19:30]>> Yeah.

[00:19:30]>> And you've got two very heavy instruments sitting here. Whereas this is now the way age has done it.

[00:19:36]>> It now given it a bit of integrity like here.

[00:19:40]>> Yeah.

[00:19:41]>> And here.

[00:19:42]>> Yeah.

[00:19:43]>> Yeah. Various times.

[00:19:44]>> It was before. Yeah.

[00:19:46]>> Yeah. Yeah. Good.

[00:19:48]>> Been a complicated paint job.

[00:19:50]>> True.

[00:19:50]>> Yeah.

[00:19:50]>> And I was looking at the old videos which I'm doing a year ago.

[00:19:54]>> Yeah.

[00:19:54]>> Putting on and you were discussing the pedals and there was two either bolts or tapered pins you wouldn't take out. Said it's not um what were they for? I never did ask that question.

[00:20:09]>> Um originally the pedals are designed to be split into two.

[00:20:13]>> Yeah. Well Derek explain me.

[00:20:18]>> Oh, these are the same one dead somewhere in there.

[00:20:21]>> As you can see, we spray these black as well.

[00:20:24]>> Yeah, we're in black.

[00:20:26]>> Believe it or not, this unit is the same as fitted to the Mustang.

[00:20:29]>> And basically what they've done is they join two together, >> you know, obviously comp compatibility.

[00:20:36]And there's to get them out the aircraft, there's a taper pin there, and there's another one over here. And you should be able to split them and take them out. But they're they're so tight in there, you're gonna cause more damage.

[00:20:47]>> Yeah, there's too too much risk of >> and also because they're a taper pin, the availability of the taper pin in the case that size, I couldn't see anywhere we could get them. But because we were stripping the whole flight deck, we could afford to take it out >> as the whole unit.

[00:21:02]>> Yeah.

[00:21:02]>> So in this case, this is the in the passer things. This has got to go back and first.

[00:21:07]>> Yeah.

[00:21:08]>> This is where the the split those two tubes then are just joining.

[00:21:12]>> Yeah. You would you could you could see here. Yeah. Yeah.

[00:21:16]>> But uh yeah, we just got to um >> Yeah.

[00:21:21]>> Oh god.

[00:21:23]>> Yeah. Yeah. I mean there's a lot of areas where where there's there's bastards we haven't taken part simply because a well a because they're very difficult to get out and b because they there no reason to to to suspect that they aren't solid.

[00:21:35]>> Yeah. Yeah. So, where that's the case, we we try and leave things as as they are.

[00:21:41]>> Cuz you could do an assessment on whether they're >> in good nick by look, you know, visual inspection.

[00:21:47]>> Yeah.

[00:21:48]>> And you're going to cause more damage >> trying to release something, you can know that uh >> he's okay. So when it comes to CA and FL and flying condition, those tubes which join the two together are okay. Even though they haven't been down, >> there's no sign of corrosion around them. And where we have taken taper pins out in other places, there's been no signs of corrosion.

[00:22:14]>> If if necessary, we could we could do some ND as well to just to give some >> I see. Yeah, you absolutely or introduce a an inspection regime with Terry. Every two years you inspect the it's all you know >> it's like what we said about inside the wing.

[00:22:31]>> Yeah.

[00:22:31]>> Yeah.

[00:22:32]>> None of it none of the metal is treated.

[00:22:33]It's pure >> you know and there's two ways you go down it. You could go and spray it with some sort of coating to protect it but then it makes it difficult to inspect >> or you can leave it >> um as it is and inspect it at regular intervals. Yeah. You know, and when you think it's been like that for 80 odd years, several getting on and it hasn't deteriorated that much. It's in the hanger, you know, you won't suddenly expect it to suddenly go, you know.

[00:23:00]>> Correct. Yeah. Yeah.

[00:23:03]>> Oh, good.

[00:23:08]The wiring looms mostly from behind the instrument panel in the cockpit. They were pulled out so Mike could paint the cockpit.

[00:23:19]as part of that process to tax whether they were rewiring anyway.

[00:23:23]>> So this most of this went behind the correct >> the instrument panel >> and it were the rear gunish control unit >> for the turrets.

[00:23:34]>> Yes.

[00:23:34]>> You got it all painted now.

[00:23:37]>> Um yeah, we did it a good while ago actually. We got all painted. Um >> of course the reservoir on this fit well.

[00:23:44]>> Yeah. Yes. Self-contained got on hydraulics.

[00:23:47]>> Yeah. hydraulic supply electric motor to build up the pressure for the trigger right directly on there.

[00:23:53]>> Yes. So that's that's the trigger mechanism and obviously the gun sit >> it's not directly connected to the guns.

[00:23:58]>> Yeah.

[00:23:59]>> As as in a Lancaster turret the the guns are lower down the pilot just sit sits with the control to the side.

[00:24:04]>> Yeah. So so we we've rebuilt it um complete and and secure obviously but but non nonoperation.

[00:24:12]>> Yeah. Look to good use.

[00:24:14]>> It will look part. Yes. Yeah. Yeah.

[00:24:16]Good.

[00:24:18]So, what you doing on this uh engine now then?

[00:24:21]>> He's uh he's trying to get a bit off, but it looks like he's going to take everything off and leave the bit sitting there. It's going to be easiest way. No, we we're >> I'm uh I need to get take the carburetor off.

[00:24:34]>> Oh, I can take the carburetor off. I've got to take this air scoop off, but I need these doors open and they're seized on the hinges here. So, I'm going to have to take off take these top three doors off to see if I can free them off and then have to work around and do all the others.

[00:24:54]>> Yeah.

[00:24:55]>> So, you just have the one um carburetor for the two sets of engines.

[00:25:00]>> What? Yeah. Yeah.

[00:25:02]>> Yeah. The carburetor's up the top there.

[00:25:04]>> Yeah.

[00:25:04]>> That's got to come off to go away for overhaul repair.

[00:25:07]>> Yeah.

[00:25:08]>> Yeah.

[00:25:08]>> But to do that, you have to >> It's quite a big unit, isn't it? Well, what I could say of it, >> you take all this off.

[00:25:14]>> Yeah. To get this off, you need to get access.

[00:25:17]>> Yeah.

[00:25:18]>> One of the jobs is to open these flaps, but they're all seized up.

[00:25:23]>> Well, they got to be eased up anyway, haven't they?

[00:25:24]>> Yeah. Just around it.

[00:25:26]>> This actuator here normally operates them as a whole lot, but it's This is moving. We thought this was seized at first. So, Andy disconnected it there.

[00:25:35]>> Yeah.

[00:25:35]>> And that moves. All right. And then we tried >> You can press it in.

[00:25:39]>> Yeah. We tried moving these.

[00:25:40]>> Just hydraulics, not air.

[00:25:42]>> Yeah. It didn't want to play.

[00:25:44]>> Yeah.

[00:25:45]>> So, we tried the old way Andy's tried the old uh penetrant oil. It's not playing. It's But because of the way the mechanics are, it's like geometric type lock stuff, but then which we fall at first, but Andy re all Well, the hinges are corroded or whatever.

[00:26:00]>> Yeah.

[00:26:00]>> Well, this one's off at the end.

[00:26:02]>> Yeah.

[00:26:04]>> Take the bracket off that holds the hinge pin.

[00:26:06]>> Yeah.

[00:26:06]>> Yeah.

[00:26:10]>> Take the whole door off then. And uh >> Yeah. Yeah. have to take it off.

[00:26:14]>> Yeah.

[00:26:14]>> The trouble is you don't really know how far the cows open.

[00:26:19]>> I would I would imagine they open quite a bit cuz >> Yeah, >> cuz you got quite a long piston.

[00:26:24]>> Yeah.

[00:26:24]>> Yeah. That retracts.

[00:26:26]>> Yeah.

[00:26:28]>> Yeah.

[00:26:31]>> And they just have the one exhaust pipe, do they?

[00:26:34]>> No, there's uh >> Yeah. On this one there's one >> there's one there. On this side, there's three cylinders into one exhaust. And then you come around and you've got separate exhausts.

[00:26:47]>> Oh, have you there?

[00:26:49]>> Yeah.

[00:26:49]>> What's that for? For the leading engine.

[00:26:53]>> Oh, no. Yeah.

[00:26:54]>> It's just the way it's just the way it's constructed. It's got all separate >> on this side, but on that side it's got one. It's obviously to do with the uh airflow and uh a lot of it to do with noise get around.

[00:27:17]So what when you say the noise to get it away from the >> This is a really really noisy cockpit and the idea was was to reduce the noise. They changed the uh exhaust cuz originally they used to come out there's different versions of it >> and the noise is horrendous. So >> they modified them.

[00:27:36]>> Yeah.

[00:27:38]>> You go tell them. You go and tell them.

[00:27:41]>> Yeah. But at some point we reckon this has got to come off.

[00:27:44]>> Yeah.

[00:27:45]>> But there's two ways of doing You can either take the flop off and take it off as one or there's bolts behind here and you can split it into into two.

[00:27:54]>> Oh, that's good.

[00:27:55]>> But you know, whatever we do, we'll try and do this and it'll be corroded. But if we took the propeller off, they would come off a piece of piss, you know. You can't you can't really win.

[00:28:06]>> Yeah. So, whatever you do, you'll have to go the long way. And if you go the wrong way, they come off.

[00:28:12]>> Yeah. Hang on, Neville. Hello, sir.
