The pilot applied full right rudder, “not realizing my feet were partially on the brakes,” and full throttle to abort the landing. The airplane turned to the right and the pilot applied left rudder to keep the airplane on the runway. The airplane entered the runway safety area, impacted a berm, resulting in the airplane becoming airborne, sending it into the parking area at the airport. The airplane impacted the top of another airplane tied down in the parking area. The right wing and fuselage were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. At the time of the accident, the pilot was landing on runway 29 with wind from 180° at 8 knots. ## Aircraft - Registration: [N8889K](https://openairdocs.org/aircraft/N8889K), registered now, S/N 108-1889 (OpenAirDocs) - Reported make and model: STINSON 108-1 - Registry model: [Stinson 108-1](https://openairdocs.org/model/stinson-108-1) (registry code 9230404) (OpenAirDocs) - Registry engine: [Franklin 6A4150 series](https://openairdocs.org/engine/franklin-6a4150-series) (registry code 27024, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 108-1889 - Year built: 1947 - Airframe hours: 1347 - Engines: Franklin 6A4-165-B3 165 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Tucker Mitchell F - Registered owner: Tucker Mitchell F - Airworthiness certificate: Standard, Normal - Last inspection: Annual, July 1, 2023, 3 hours before - Destination: Same as departure - Airport: BVS, Skagit Regional Airport, runway 29, 5,480 × 100 ft, asphalt - Equipment: Electronic primary flight display, Electronic multifunction display, ADS-B, Stall warning system ## Flight crew As NTSB recorded them.
