The airplane yawed left and settled to the runway. The airplane subsequently veered off the runway into a grass field, resulting in substantial damage to the left aileron. The flight instructor further stated that becoming slow, and the inadequate application of the rudder could have been contributing factors. Both pilots stated that there were no preaccident failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N9338V](https://openairdocs.org/aircraft/N9338V), registered now, S/N 700004, built 1969 (OpenAirDocs) - Reported make and model: MOONEY M20E - Registry model: [Mooney M20E](https://openairdocs.org/model/mooney-m20e) (registry code 5870212) (OpenAirDocs) - Registry engine: [Lycoming I0360 series](https://openairdocs.org/engine/lycoming-i0360-series) (registry code 41515, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 700004 - Year built: 1969 - Airframe hours: 5530.5 - Engines: LYCOMING IO-360 SER 180 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, December 3, 2023 - Departed: SQL, San Carlos, CA - Destination: Same as departure - Airport: C83, Byron Airport, runway 30, 4,500 × 100 ft, asphalt - Equipment: Auto-pilot, ADS-B ## Flight crew As NTSB recorded them.
