Failure of the tail retraction jack ram seals can also prevent the main gear being retracted and/or locking down as the fluid would cycle around the circuit and pressure would not build up.
This problem is identified by selecting the gear down before engine start. On start up the gear lever flicks into idle when pressure builds to 1100psi. If it does not click into “Idle”, you don’t go fly. This of course could also indicate failure of the hydraulic pump.
Initially the blow down bottle was connected to the main jacks only. A later modification added a shuttle valve to the tail retract jack so that all three legs could be blown down.
I thought the rivet replacement comment was interesting too. Why a ‘Cat 3 repair’ was she pranged at some point or was it just a serious case of ‘Irish Woodworm’:D Just curious.

During winter servicing at Coningsby in 1978 a few rivets had popped on the port flap. On replacing them a few more surrounding let go. On closer inspection many more magnesium rivets were found to have failed or were about to fail. It soon became obvious that the work was beyond the resources of the BBMF and teams were called in from No. 71 MU at Abingdon. The aircraft was grounded for eighteen months whilst repairs were made but this was only the start of the work carried out by 71 MU.
“Cat 3” was the fact that the work was beyond unit resources and not because it was involved in an accident.
The planes and the thread got buried! I wonder why? Has somebody found something????????????????
A Legendary preview!
Some very brief detail.
Lancaster I Merlin XX Hamilton A5/138, DH 5/40, DH5/40H (DH hub)
Lancaster II Hercules VI Rotol RE8/36/1, 2,5 & 6. Semi flared used in emergency only.
Lancaster II Hercules VI Rotol RE9 series with fully flared blades.
Lancaster III Merlin 28 DH 5/40 & 5/40H
Lancaster III Merlin 28 Hamilton A5/138 & A5/148
Having seen the picture on ebay, definitely not Spitfire.
It has a size 6 shaft from a radial then it could be from a Tempest II fitted with an R21/4B6. The pitch change is similar to Sea Fury.
There are several other possibilities which could be proved/disproved with further detailed information and an installation drawing showing attachment of the pitch change mechanism. They are Firebrand R23/4B6, Buckingham R16/4B6 & Warwick R17/4B6.
Five for the price of one. Race against time, Legends 2007. Gladiator, Spitfire XVIII, P-47G, P-40B and Mustang TF-51!
Hi – definately no CAA invovlement in this incident.
Welcome to the forum and thanks for confirming the incident. Tell us more!
Hercules Engines Rotax Direct Electric Starter with Hand Crank, Types C1231 & C1247/2.
Fitted to Hercules VI to XX, 100, 101, 608, 130, 630, 650, 670, 230, 730 and 750.
Depending on the installation the hand crank could be arranged in 15 degree stages.
Hercules 120, 260 and 760 used a different starter.
Looks like Bristol Hercules starter.
One of the higest scoring RAF pilot is the almost forgotten ‘Bob’ Braham.

Like Peter Cornwell I watched the Channel 4 screening with great interest. It brought back many memories of my first dig on Gerhard Granz’s Bf110 as an amateur and my first dig as a professional with 71 MU to recover a Hurricane from a peat bog at RAF Spadeadam where we identified the aircraft and the pilot on site. No room for a bucket and trowel on that one, we nearly lost the digger!
Commend the research, investigation, presentation and your restraint on this thread. Continue to enjoy the hobby and occupation which we have both enjoyed for more years than I care to count.

Both Mk. 1 & Mk. II Spitfires could have wooden elevators and rudders. Spitfire Mod. 265 (rudder) and 286 (elevator) introduced wooden controls as an alternative material.
Something new every day!
Also used on trolley accs. circa 1950-60’s.
Guys & Girls
I’m glad that you like what we do at TFC. At the moment we could do with a little help. As you know we have a fair work load on with turning round the Spit XVIII and P-47G. The Gladiator is progressing well and on target, but there is more to do.
Our problem is that our volunteer work force has become rather depleted for varying reasons, girlfriends, marriage, babies, old age, the wife/husband won’t let me, better things to do etc.
Just want you to turn up on a regular basis, carry out the crap jobs that are thrown at you, paint strip some P-47/Spitfire parts, clean the hangar floor, move the ground equipment, drive the tractor (you might just be towing your favourite aircraft), and then sit in a Spitfire! Would that make your day? If so PM me to join the gang. Sunday is the regular day but if you can come in during the week, “Sign Up”.
