He inadvertently raised the landing gear handle instead of the flap handle, and the landing gear began to retract. The airplane struck the ground and slid to a stop on the runway, which resulted in substantial damage to the airplane’s left wing. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N35S](https://openairdocs.org/aircraft/N35S), registered now, S/N D-7481, built 1964 (OpenAirDocs) - Reported make and model: BEECH S35 (NO SERIES) - Registry model: [Beech S35](https://openairdocs.org/model/beech-s35) (registry code 1151532) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: D-7481 - Year built: 1964 - Airframe hours: 5796.6 - Engines: Continental IO-540-BA3B 285 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, October 6, 2025, 0 hours before - Destination: Same as departure - Airport: OLM, Olympia Regional Airport, runway 17, 5,500 × 150 ft, asphalt - Equipment: Auto-pilot, ADS-B, Stall warning system ## Flight crew As NTSB recorded them.
