Hi all

We’re busily building up the flightdeck structure and whilst I’m slaving away in the heat working out how the footrest structure all fits together, Cliff has been beavering away reconstructing the control panels that sit in front of the first and second pilots.

First up is the Propeller Feathering Panel directly in front of the 1st Pilot, this was based on an original example that was kindly loaned to us by the Fenland Aircraft Museum. Theirs was missing the support bracketry which we’ve recreated using some very grainy photos as the basis.

The second is the Airscrew de-icing switch and Booster Coil switch panel, that mounts directly in front of the 2nd Pilot. As always, we’d like to express our thanks to Screens and Graphics of Cottenham who kindly recreated the labels for us.

We can’t mount these to the main instrument panel structure as yet as we’ll have to design the proper main panel mounting structure, either way they show just how cluttered an ergonomic slum the Stirling cockpt was. Getting there slowly 🙂

well Cees

If you can go as far as Cambridgeshire, there’s a certain Stirling that awaits your attention 🙂

As promised last weekend, the P2 control column fwd stop assy is now finished and permanently installed. I’ve been told to stop working on the easy stuff and choose something a bit more challenging!:rolleyes:

The next week or so should see the completion of the Prope feathering and Booster Switch/Airscrew de-icing panels

Thanks Mike

It feels like we’re going at a snail pace some times but we are starting to see some real progress

Thanks TA, it all takes time but we’re getting there. There’s plenty of other areas being worked on at the moment, just not quite ready to report yet

slow and steady wins the race 🙂

following on from my last post, the P1 fwd control column stop is now permanently installed and painted with P2 to follow next week. The 2 bare metal channels attached to the box are the first parts of the rudder pedal footrests (only 4 to make of those LOL). I’m 95% certain of the construction of these based on photos looking down from above and upwards from the Bomb Aimers compartment. the latter are always in shadow and it’s hard to define what’s there but we’re pretty much on top of the design now.

Any way without further ado please see the pics below showing the P1 stop assy.

They still exist (in a much diminished form) as defence Quality assurance – Field Force DQA-FF

the tapered shiny part looks to be the roller in the ammunition guide for the nose/mid-upper gun turret. Can’t say what the other parts are

As far as I recall, the GR3 wings remained within the fleet as FI had to be micromanaged, wing swaps became routine activity at St Athan as there were never enough wings around. No idea how the Omani wings were managed, but I do recall that the GIA ban didn’t last much into the 2000s.

Although the later fleet may have been reaching the higher end on fatigue the RAF did possess a fleet of low houred frames that were the ex RAFG fleet relegated to training aids, as design authority had passed to the RAF I believe, they could have been brought up to GR3 standards utilising the fit on the existing fleet, however those wings were I think swapped out with the Omani Jags to keep them in service.. If you wanted low hour rust buckets the Nigerian fleet had a max of about 100 hours on them, we also even paid for them if I am correct as the UK stood guaranteer on them and Nigeria renaged after a few payments.

In 97 when I joined the EA, the GIA wings were not allowed to be worked on by the trainees, however to make them suitable for the active fleet they needed some significant fatigue mods especially the plates under the centre wing which were made of unobtanium….. The Nigerian wings were looked at but the same again and having been baked in the African sun for some time all of the PRC in the tanks needed replacing as it had crumbled away. The cost of demodding the GR3/3A and updating the GR1s would have been prohibitive given that the fixed wing fleets were being reduced across the board

Hi Ant

Some time since I left the Engineering Authority, but a lot will depend on the utilisation rate of the aircraft, whether any of the fatigue improvement mods have been incorporated into new build wings and whather the Indians have made enough wings to be able to swap them around to make best use of remaining life.

Enjoyed working on them (1st ac I cut my teeth on) and also spent nearly 8 years in the EA which was one of the best years I’ve had in my career thus far. Miss them a lot, just wish the missus would let me have one as a gate guard LOL

Regards the decision to retire them, wasn’t there some sort of fatigue problem with the wing attachments??

Jags had a life extension that took them from 6000 to 7000 flying hours. The wings were being flown by inspection as there was an issue with inner and outer wing Fatigue Index calculations and most wings had concessions against them regarding a hole position at the rear spar which was a fatigue critical zone. The critical crack limit at this point was 0.5mm after which point the wing would probably unzip!

Coupled with stress corrosion in the frame 25 u/c mounts meant it was becoming labour intensive to maintain. Sad but she did give nearly 35 years of good service so I dare say the tax payer got their money’s worth out of the airframe

hi Andy

they could be but Shorts have given them a unique LH and RH Pt No. It could be that they have a small modification from a standard part. They’re not very big as you can see in comparison to the bulb holder in the AP extract
