The pilot attempted to correct by applying the left rudder and left brake. The airplane came to rest upright about 20 ft off the right side of the runway. Postaccident examination of the airplane revealed the left main landing gear was collapsed, and the airplane sustained substantial damage to the left wing. The pilot reported there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N9HU](https://openairdocs.org/aircraft/N9HU), registered now, S/N 44-17334, built 1944 (OpenAirDocs) - Reported make and model: STINSON L-5 - Registry model: [Stinson L-5](https://openairdocs.org/model/stinson-l-5) (registry code 8630202) (OpenAirDocs) - Registry engine: [Lycoming 0-435A/0-435C](https://openairdocs.org/engine/lycoming-0-435a-0-435c) (registry code 41517, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 44-17334 - Year built: 1944 - Airframe hours: 2173 - Engines: Lycoming O-435-11 185 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Alamo Liaison Group - Registered owner: Alamo Liaison Group - Airworthiness certificate: Standard, Normal - Last inspection: Annual, August 16, 2024, 3 hours before - Departed: 53T, San Antonio, TX - Destination: Same as departure - Airport: PEZ, Pleasanton Municipal Airport, runway 16, 4,000 × 75 ft, asphalt - Equipment: ADS-B ## Flight crew As NTSB recorded them.
