Aircraft Accident/Incident Report
Monroe, Washington 98272
Friday, May 1, 1998 15:00 PDT
NTSB Narrative Summary Released at Completion of Accident
After the instructor simulated an engine failure by pulling out the mixture control until the engine shut down, the student attempted to maneuver for a landing at a paved private airstrip. Just after turning a close-in final, with the mixture still pulled out almost to the full-lean position, the student raised the aircraft's nose, and the propeller stopped turning. The instructor then returned the mixture control to the full rich position and instructed the student to engage the starter. After two unsuccessful attempts to get the engine to start, the student landed the aircraft in an area where the terrain had been torn up by construction workers. Just after touchdown, the aircraft impacted rough/uneven terrain and sustained substantial damage.
NTSB Probable Cause Narrative
Fuel starvation due to the flight instructor's improper in-flight decision to simulate an engine failure by pulling the mixture control toward the lean position until the engine shut down, and his failure to return the mixture to the rich position until after the aircraft had reached a low altitude and the propeller had stopped turning. Factors include the rough/uneven terrain within the construction area in which the aircraft was landed.
