The pilot applied full power, raised the landing gear, and initiated a climb out. At the same time, the pilot-rated passenger, inadvertently raised the flaps prematurely, which caused the airplane to settle onto the runway with the landing gear retracted. Once the propeller contacted the runway surface, the airplane veered off to the right of the runway and sustained substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N300JS](https://openairdocs.org/deregistered/N300JS-2021-07-30), registration cancelled 2021-07-30, S/N 21062717, built 1978 (OpenAirDocs) - Reported make and model: CESSNA T210 (M) - Registry model: [Cessna T210M](https://openairdocs.org/model/cessna-t210m) (registry code 2073451) (OpenAirDocs) - Registry engine: [Continental TSIO-520 series](https://openairdocs.org/engine/continental-tsio-520-series) (registry code 17040, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 21062717 - Year built: 1978 - Engines: Continental TSIO-520 Series 310 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Nor Cal Perlite Inc - Airworthiness certificate: Standard, Normal - Departed: CCR, Concord, CA - Destination: BIH, Bishop, CA - Flight plan: VFR/IFR - Airport: O57, Bryant Field, runway 16, 3,854 × 60 ft, asphalt - Equipment: Unknown ## 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.
