What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Acft was slow on final and landed hard, the seat broke loose and came down on the aileron controls, and the acft ground looped on the rwy. (-23)pilot reported that when turning from base to final a shudder was felt in control stick. Descent seemed normal until he tried to flair. When he tried to flair he had no elevator response, and landed hard at this point the plastic seat broke. When the seat broke it came down on the aileron cables. The weight on the cables rendering. The ailerons inoperable. The right main gear strut bent and the aircraft tipped onto right wing. Investigation revealed that the stabilator trim netuator had broken at the hard mount leaving free to move up or down. This was probably the shudder felt in stick and would make elevator control ineffective.
