Subsequently, the airplane turned to the right and the left wing contacted the ground, which resulted in substantial damage to the left wing. The pilot reported selecting runway 22 for landing. He reported the winds to be from 120° at 11 kts, gusting 18 kts. On previous flights, the pilot would land on the gravel area adjacent to the asphalt runway during crosswind conditions; however, prior to the accident flight, he was advised that landing on this area was no longer authorized. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N2694D](https://openairdocs.org/aircraft/N2694D), registered now, S/N 20846, built 1952 (OpenAirDocs) - Reported make and model: CESSNA 170B - Registry model: [Cessna 170B](https://openairdocs.org/model/cessna-170b) (registry code 2072306) (OpenAirDocs) - Registry engine: [Continental C145 series](https://openairdocs.org/engine/continental-c145-series) (registry code 17012, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 20846 - Year built: 1952 - Engines: Continental C145 145 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 26, 2025, 19.1 hours before - Destination: Same as departure - Airport: HOM, Homer Airport, runway 22, 6,701 × 100 ft, asphalt - Equipment: Stall warning system, Electronic flight bag or handheld device ## Flight crew As NTSB recorded them.
