Lead in paragraph on Mod 58
An incident occurred to the company demonstrator aircraft G-GBXS where one
of the TP16
anti-servo/ trim tab drive pins became detached due to the plate it was wel
ded to fracturing. The
aircraft was on the ground when the failure occurred, probably during engin
e starting, and the
resulting behaviour of the aircraft in flight was to pitch nose up. The pit
ch up force was containable by the pilot and a circuit and landing was succ
essfully flown.
The fracture was established to have been caused by fatigue due to repeated
bending of TP16=A2s plate.- The bending that this plate had been subject
ed to was likely to have been in excess of normal due to ibrations caused b
y an engine starting problem. The aircraft had completed 426 hours of fligh
t which included 895 take-off and landings. It is important that the cause
of unusual vibrations, for example engine starting problems or an unbalance
d propeller, are resolved at the earliest opportunity.

Hello All,
My rebuild is now on to the trim tabs......
I understand that Mod 58 was the replacement fitting of the trim tab drive
pins. Does anyone know why? I've looked in the factory newsletters and
can't seem to find the reason for it.
Thanks,
Phil
