The defining event best describes what happened. - [Landing-flare/touchdown: Runway excursion](https://openairdocs.org/ntsb-events/300) (defining event); cases with it: [Cessna 172S, 76 cases](https://openairdocs.org/ntsb-events/300/sequence.md?model=2072439), [All aircraft, 3,643 cases](https://openairdocs.org/ntsb-events/300/sequence.md) ## Analysis The pilot completed the approach to her home airport with a right crosswind correction applied. She explained that the right main landing gear touched down first, the airplane bounced, and the airplane yawed to its left. The pilot said the airplane did not respond to her control inputs to realign with the landing runway, and that she did not abort the landing after the runway excursion because there were trees to the airplane’s immediate front. The airplane came to rest upright in the grass apron on the runway’s left side. The pilot was unhurt, and the airplane sustained substantial damage to the firewall and nose landing gear mount structure. The damage to the structure was consistent with an aerodynamic stall and hard landing on the nose landing gear. A post-accident examination of the airplane by an FAA aviation safety inspector revealed flight control continuity from the flight controls to all flight control surfaces. ## Aircraft - Registration: [N5185U](https://openairdocs.org/aircraft/N5185U), registered now, S/N 172S9059, built 2002 (OpenAirDocs) - Reported make and model: CESSNA 172S - Registry model: [Cessna 172S](https://openairdocs.org/model/cessna-172s) (registry code 2072439) (OpenAirDocs) - Registry engine: [Lycoming IO-360-L2A](https://openairdocs.org/engine/lycoming-io-360-l2a) (registry code 41597, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 172S9059 - Year built: 2002 - Airframe hours: 6360 - Engines: Lycoming IO-360-L2A 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Moyer Aviation Inc - Registered owner: Moyer Aviation Inc - Airworthiness certificate: Standard, Normal - Last inspection: Annual, April 27, 2021, 92 hours before - Departed: WBW, Wilkes-Barre, PA - Destination: Same as departure - Airport: MPO, Pocono Mountains Muni, runway 13/31, 5,001 × 75 ft, asphalt - Equipment: Auto-pilot, ADS-B ## 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.
