NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
After takeoff from runway 28, at an altitude of 600 feet msl, the pilot initiated a right turn. During the turn, the engine began to "run rough," and the engine rpm decreased to between 1,800 - 2,000 rpm. The flight instructor told the pilot to return to the airport, and the pilot set up the airplane for a downwind landing on runway 10. When the airplane was halfway down the runway, the pilots decided to perform a go-around. They applied full power, and initiated a "slight" climbing right turn above trees at the departure end of runway 28, and then a left turn to return for landing on runway 28. During the turn, the aircraft "entered an accelerated stall," and the left main landing gear impacted the ground. The airplane continued across a grass area and struck a group of trees. Examination of the engine revealed the number 3 cylinder contained a crack from the spark plug hole to a point between the cylinder intake and exhaust valve. The most recent annual inspection was performed 2 months prior to the accident, during which no abnormalities were noted with the cylinders. At the time of the accident, the wind was from 250 degrees at 7 knots. The airport consisted of two runways; runway 10/28, which was 6,002 feet long by 150 feet wide, and runway 14/32 which was 5,057 feet long by 150 feet wide.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The flight instructor's improper in-flight decision to perform a emergency landing to a runway, with a tailwind, and his failure to maintain airspeed after aborting that landing, which resulted in an inadvertent stall and subsequent impact with terrain. Factors in the accident were the partial loss of engine power due to a cracked cylinder, and tailwind condition. Full narrative available
