The NTSB's narrative final · quoted from the NTSB record
AT ABOUT 215 KTS THE PLT ROLLED THE ACFT IN ORDER TO EVALUATE NEWLY INSTALLED AILERONS. IT HAD BEEN NOTED EARLIER THAT A DEAD-BAND EXISTED IN THE AILERON NEUTRAL RANGE THAT INCREASED WITH AIRSPEED. THE PLT STATED THAT UPON ROLLOUT THE DEAD-BAND WAS STRONGER & SLOWED THE RECOVERY WHICH RESULTED IN AN ADDITIONAL ROLL. AS THE ACFT CONTINUED ITS ROLL, THE NOSE-DOWN ATTITUDE INCREASED CAUSING THE ACFT TO ACCELERATE AT AN EVER INCREASING RATE. DURING THE ROLLOUT OF THE SECOND ROLL, THE STICK RESISTANCE CAUSED THE PLT TO PUSH CONSIDERABLY HARDER, INADVERTENTLY PUSHING THE STICK THROUGH NEUTRAL TO THE OPPOSITE SIDE. AN IMMEDIATE AND RAPID AILERON ROLL REVERSAL RESULTED & ANY ACTION THAT THE PILOT TOOK WOULD NOT AFFECT THE RATE OF ROLL OR DESCENT. THE PLT EJECTED BELOW 3000 FT MSL WHILE IN INVERTED FLT.
