    The recovery is now officially closed, and landscaping nearly finished. Heavy equipment was moved to Werkendam, where yesterday the excavation of Lancaster LM508 started. This 101 Squadron aircraft went down on June 22nd, 1944 killing bomb aimer F/S T.H. Duff (parachuted out but died of injuries). Six other crewmembers escaped by parachute. Tailgunner Sgt. J.E. Keogh perished in the crash, and is remembered on the Runnymede memorial. It is hoped his remains will be found during the recovery at Werkendam.

    The main Fuselage number should have retained the original identity.

    I have a T21 in the shop that has had three different front fuselage fitted (accident repairs), with two (FF) fuselage numbers, the last one no longer legible. It is not a problem. The framenumbers are not the s/n associated with the aircraft’s ID for registration.

    On T38’s it was common practise to even exchange whole front and/or rear fuselages in repairs, with the paperwork only retaining the identity of the aircraft.

    Quite a lot of Slingsby aircraft actually had FF and RF numbers that were separate. Then there’s the composite aircraft (e.g. the T38 that was built with a new fuselage and refurbed T7 wings, compiled from whatever major sections were ready at the time using the old and new numbers mixed).

    Slingsby frame numbers are a bit of a minefield.

    Surprising they opted to dispose of the helicopters, which are original and complete (and look in good condition) on the basis of duplication and relevance, but overlooked a plastic Typhoon, Swiss-built Vampire, derelict PT-19 and the Miles Mohawk (how long did that actually spend on display?!)
    It’s also a bit of a shame that Hendon or Cosford can’t find a small space for the Proctor-whose significance to the RAF is quite considerable.

    From the first line of the document linked: ‘The Royal Air Force Museum has reviewed its current holdings in the Helicopter Collection’. I may have overlooked a rare prototype or two, but I am fairly certain the museum does not hold helicopter-versions of the Typhoon, Vampire, PT-19 or Mohawk.

    You’d need to clear out your Inbox for the PM first then.

    Eric -I am inclined to give this one a go to fly again! Whilst its not in great condition -it will be a good exercise for a friend who wishes to extend his woodworking skills!

    That would be nice. They fly as they look, but they’re great fun! If any parts are missing, let me know and I’ll see what’s there. And like Dave pointed out: watch out for Mod 80, lots of work.

    Yeah, I have been working on a T21-wing that was MHL-built for some months now. There’s a steep amount of Slingsby-built ribs in there not matching maintenance records, and probably in there since manufacture. The MHL-number is also out of sequence for the number on the line.

    Thanks Eric ! Yes thats the rudder ! I have just picked up a Tutor which looks the spitting image of BGA466 ! However I delivered that to Hooton Park a few weeks ago so I need to do some detective work on this one!

    There’s one or two Slingsby expert on the forum here, so fingers crossed. The c/n of Slingsby-built gliders of the older generations are a bit of a headache, and are rarely in the gliders themselves. A FF-number could help if it is in sequence. Is it complete, or would you be needing parts to get it up to display standard?

    Any Tutor experts out there that can shed some light on the number ???

    Sounds like the serial number for the rudder of the aircraft.

    SSK= Slingsby Sailplanes Kirbymoorside
    R = Rudder
    441 = s/n of the rudder

    Most Slingsby’s have a number likes this on major components:
    SSK/FF/.. is front fuselage
    SSK/RF/.. is rear fuselage
    SSK/OW/.. is (outer) wing
    SSK/A/.. is aileron
    etc.

    The numbers can usually be found on a piece of paper framed in a bit of perspex on a squarish sunk bit in the plywood.

    Some SSK/FF/.. numbers may be matched against individual aircraft. Most SSK/… numebrs have been changed over so often they are no longer traceable.

    It is a Fokker project wich was shown at le Bourget pre WW2.

    Indeed. A Fokker C.I, registration PH-APL. Modified by Syndicaat Dekker Octrooien from The Hague between 1937 and 1940. Owner Adriaan Dekker was a windmill designer. Aircraft was impounded by German forces at Ypenburg May 18th, 1940 following the invasion of The Netherlands and transported to Berlin. Is rumoured to have been flown there but crashed on first flight.

    And to show what flutter will do to a wing, here’s a movie:

    – A DG glider with the aileron ballast weights taken off so that the CoG of each aileron is too far backwards and flutter starts far below Vne: https://www.youtube.com/watch?v=kQI3AWpTWhM

    Control system stiffness plays a large role as well. Cable-driven ailerons tend to have large counter balance weight fitted. Compare the Rhönlerche which has about 3 kilos of lead in large protruding counterbalance weights, fitted after a couple of them lost their ailerons (and in one case the wings) in dives due to flutter.

    Then there’s the P-51D recovered from shallow waters near Harderwijk in 1977: http://www.flevolanderfgoed.nl/home/erfgoed/zuidelijk-flevoland-2/vliegtuigwrakken/vliegtuigcrash-mustangs-p51-d.html (after a swimmer cut from the nearby beach cut his foot on it)

    Also, did you ever hear, back in the 80s, of a Mustang reserved for a cor Groenevald who (I think) was a member of the DDA? I seem to remember from Flypast of the day that the reg was to be PH-MMF.
    T J

    Cor Groeneveld (not Groenevald, but he was indeed president of the DDA at the time) reserved a registration for a P-51 but the dream never came true. Not meant for DDA, but for himself (he owned a Harvard at the time, and an S-11 before that).
