Analysis

The flt was to test a newly installed airspeed indicator. A passenger who went on the flt survived the accident and saidthe pilot had done an aileron roll from 4000 ft MSL (about 1700 ft AGL) and had buffeted and lost alt during recovery. After a high speed pass over the arpt the pilot climbed to about 3000 ft MSL did a 180 degree turn. He did another aileron roll and when the acft came out of it a buffet occurred and the acft hit the ground before recovery was completed. It could not be established that the pilot had any aerobatic training.
