Hello Ray
It seems that u have a good experience on the FF, any way so do u think this a possible cause to what happened .....! by the way so may be they started a right hand spin then he applyed the recovery actions which is full left rudder, but may be it stucked there and didnt come out, so ,what do u think?

Sorry for the repated massage twice

I can only suggest you inspect the clearances on the rest of your fleet and talk to the manufacturer. Possible damage/ reduced clearance due to over turning the nosewheel steering while towing/ground handling is a concern to me whenever I see an aircraft moved with the engine covers off.

Early in EFTS service there was an incident where the rudder pedal/linkage jammed at full deflection in a spin. It required both pilots to stamp on the pedal repeatedly to free it off.

Subsequent inspection showed that part of the linkage had been incorrectly assembled at the factory and could jam at full travel. Something simple like a washer being fitted in the wrong place, if memory serves me right.

Yes that incident was in the early days of JEFTS at Topcliffe in a 160hp T67M (1993?). The more recent example highlighted by Beagle (AAIB Safety Recommendation 2007-077) resulted in the SI issued by Slingsby to all owners.
I have had no response from Slingsby yet over this one - possibly because the facts are still under investigation.
