During the landing roll, the student pilot intended to retract the flaps, but accidently extended the flaps further. While correcting the flap setting, the student pilot transferred his attention inside the cockpit and the airplane veered to the left. The student pilot pulled the throttle back before the airplane departed the side of the runway. The airplane’s nose wheel collapsed, and the airplane came to rest in the grass resulting in substantial damage to the fuselage. An examination of the airplane did not reveal any flight control anomalies. ## Aircraft - Registration: [N5937G](https://openairdocs.org/aircraft/N5937G), registered now, S/N 15071437, built 1969 (OpenAirDocs) - Reported make and model: CESSNA 150K (K) - Registry model: [Cessna 150K](https://openairdocs.org/model/cessna-150k) (registry code 2071822) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 15071437 - Year built: 1969 - Engines: LYCOMING 0-320 SERIES 180 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Doomac LLC DBA - Airworthiness certificate: Standard, Normal - Destination: Same as departure - Airport: FLY, Meadow Lake, runway 15, 6,000 × 60 ft, asphalt ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
