As part of the extended 50 hour service I have been re greasing all the hinges and checking all fixings
Part of that check was to clean and check brakes and also re grease the wheel bearings after so many landings
Jacking the aircraft up has always been interesting ..I am always concerned that I don’t damage something by squashing or bending whentaking the entire weight.
I remember in the barn build days loosely jacking the centre of the undercarriage and taking the centre wheel bolt out … not realising that the geometry of the u/c meant it immediately did a ‘Bambi’ on me and played her legs wide apart ! … moral of the story .. keep the legs braced or tied together if removing a wheel .. or have a grab point around the engine
