The pilot added full power to abort the landing and applied forward pressure on the control yoke to keep the nose down. Before a climb rate could be established to clear trees at the end of the runway, the airplane again stalled, touched down, and the landing gear collapsed. The airplane slid off the runway and the fuselage was substantially damaged. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N1958Q](https://openairdocs.org/deregistered/N1958Q-2020-09-21), registration cancelled 2020-09-21, S/N 177RG0358, built 1973 (OpenAirDocs) - Reported make and model: Cessna 177RG (No Series) - Registry model: [Cessna 177RG](https://openairdocs.org/model/cessna-177rg) (registry code 2073709) (OpenAirDocs) - Registry engine: [Lycoming IO-360-A1B6D](https://openairdocs.org/engine/lycoming-io-360-a1b6d) (registry code 41593, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 177RG0358 - Year built: 1973 - Airframe hours: 1184.9 - Engines: Lycoming IO-360-A1B6D 200 horsepower reciprocating - Damage: Substantial damage - Flight: Positioning, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, February 20, 2020 - Departed: RNT, Renton, WA - Destination: 38W, Lynden, WA - Flight plan: IFR - Airport: 38W, Lynden Municipal Airport Janse, runway 07, 2,425 × 40 ft, asphalt - Equipment: ADS-B ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
