During the landing, when she reached to adjust the flap setting, she inadvertently increased the throttle. She responded by applying braking, but the airplane ultimately departed the end of the runway and impacted trees. The airplane sustained substantial damage to both wings and the fuselage. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation, and that instead of landing at the accident airport, she should have diverted to an airport with a longer runway that was more oriented into the wind. ## Aircraft - Registration: [N72CM](https://openairdocs.org/deregistered/N72CM-2025-01-22), registration cancelled 2025-01-22, S/N 17266517, built 1975 (OpenAirDocs) - Reported make and model: CESSNA 172 (M) - Registry model: [Cessna 172M](https://openairdocs.org/model/cessna-172m) (registry code 2072418) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17266517 - Year built: 1975 - Airframe hours: 4278.7 - Engines: LYCOMING O-320-E2D 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, April 20, 2024, 7 hours before - Departed: BKV, Brooksville, FL - Destination: Same as departure - Airport: 5FL7, TWELVE OAKS Airport, runway 22, 2,600 × 100 ft, grass/turf - Equipment: Stall warning system, Electronic flight bag or handheld device, Auto-pilot, ADS-B ## Flight crew As NTSB recorded them.
