However, shortly thereafter, he could not maintain directional control of the airplane on the landing roll and the airplane drifted towards the right and then departed the runway surface. The airplane subsequently nosed over and sustained substantial damage to the fuselage and wings. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N5930R](https://openairdocs.org/aircraft/N5930R), registered now, S/N 17253599 (OpenAirDocs) - Reported make and model: CESSNA 172G - Registry model: [Cessna 172G](https://openairdocs.org/model/cessna-172g) (registry code 2072420) (OpenAirDocs) - Registry engine: [Continental 0-300 series](https://openairdocs.org/engine/continental-0-300-series) (registry code 17022, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17253599 - Year built: 1965 - Airframe hours: 20150.1 - Engines: CONT MOTOR 0-300 D 145 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Downwind Corp - Airworthiness certificate: Standard, Normal - Last inspection: Annual, October 24, 2020 - Departed: SPB, Scappoose, OR - Destination: KLS, Kelso, WA - Airport: KLS, Southwest Washington Rgnl, runway 12/30, 4,391 × 100 ft, asphalt - Equipment: ADS-B, Electronic flight bag or handheld device ## Flight crew As NTSB recorded them.
