Analysis

According to the plt's son the plt routinely overflew his home and rocked the wings. The plt indicated that he was flying at 1100 ft MSL (aprx 650 ft AGL) over his son's ranch and decided to demonstrate slow flt. He slowed the acft to 70 mph and made one circle. The plt then decided to make a second circle. He stated, 'forgetting that I was already at a slow speed - upon entry into a steep left turn, the aircraft stalled.'
