During touchdown, the airplane “skipped” over the runway surface, and turned to the left side of the runway. The passenger inadvertently applied brakes and the airplane subsequently nosed over and came to rest inverted. The vertical stabilizer and wing struts sustained substantial damage. The pilot reported that the airplane had no preimpact mechanical malfunctions or failures that would have precluded normal operation. ## Aircraft - Registration: [N5636D](https://openairdocs.org/aircraft/N5636D), registered now, S/N 7305C, built 1979 (OpenAirDocs) - Reported make and model: MAULE M-5-235C - Registry model: [Maule M-5-235C](https://openairdocs.org/model/maule-m-5-235c) (registry code 5460135) (OpenAirDocs) - Registry engine: [Lycoming 0-540 series](https://openairdocs.org/engine/lycoming-0-540-series) (registry code 41532, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 7305C - Year built: 1979 - Airframe hours: 1980.9 - Engines: Lycoming O-540-1A50 235 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, May 19, 2024, 1.2 hours before - Destination: Same as departure - Airport: U78, Allen H.
