The airplane sustained substantial damage to the left wing. The pilot suggested that a gust of wind may have contributed to the accident. Weather conditions at the nearest observation facility (located about 5 miles northeast of the accident site) included wind from about 10° left of the runway heading at 11 knots near the time of the accident. The pilot reported that there were no preaccident mechanical malfunctions or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N4464Y](https://openairdocs.org/deregistered/N4464Y-2023-02-06), registration cancelled 2023-02-06, S/N 7267C, built 1979 (OpenAirDocs) - Reported make and model: MAULE M5 (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: 7267C - Year built: 1979 - Airframe hours: 2410 - Engines: Lycoming O-540-J1ABD 235 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, November 13, 2020 - Departed: ANP, Annapolis, MD - Flight plan: VFR - Airport: ANP, Lee Airport, runway 12, 2,500 × 48 ft, asphalt - Equipment: ADS-B ## Flight crew As NTSB recorded them.
