Analysis

The pilot was demonstrating a stall to the passenger. During the recovery, the airplane continued to descend with full power applied, and the main landing gear struck a rock wall. The airplane flipped over and came to rest in a corn field. The pilot reported he had not compensated for the additional weight of the passenger when he performed the stall.

Factual Information

On September 26, 1998, about 1630 eastern daylight time, a Cessna 140, N72929, was destroyed during recovery from a practice stall near Waterbury, Connecticut. The certificated commercial pilot/owner and pilot rated passenger received minor injuries. Visual meteorological conditions prevailed for the personal flight that originated from Waterbury-Oxford Airport, Oxford, Connecticut. No flight plan had been filed for the flight that was conducted under 14 CFR Part 91. According to a statement from an Inspector with the Federal Aviation Administration (FAA): "[The pilot]...stated 'I goofed'. During the flight that day he had been talking to his passenger..., about emergency landings. He had explained the techniques for keeping the aircraft under control if an emergency landing was required. [The pilot]...flew the aircraft over the farm owned by [the passenger's]...cousin. [The pilot]...showed...[the passenger] how to slow the airplane down and control it through a stall. [The pilot]...stated he was not watching his altitude. After the stall, he pushed the nose of the aircraft down and applied power. He returned the aircraft to a level attitude, but the aircraft continued to sink. He stated that [the passenger]...weighted approximately 200 pounds, and he did not account for the additional weight during the stall. The aircraft lost more altitude than he anticipated, even though the engine was running 'full bore'. [The pilot]...stated that 'if we had 3 feet more, we would have made it'. He did not see the stone wall at the end of the corn field, only the corn stalks. The next thing he knew he was upside down in the aircraft with the seat belt holding him in. He checked his passenger's condition, and proceeded to get out of the aircraft...." The FAA Inspector reported that the main landing gear contacted a rock wall and the landing gear box was ripped out of the fuselage. The empennage had separated from the fuselage. The engine and firewall were connected to the forward fuselage by control cables, and the wings were bent. The passenger held a private pilot certificate; however, he was not operating the flight controls or receiving flight instruction.

Probable Cause and Findings

Was the pilot's misjudged altitude of the airplane prior to performing a stall, and which resulted in the main landing gear contacting a rock wall.
