The defining event best describes what happened. - [Takeoff-rejected takeoff: Runway excursion](https://openairdocs.org/ntsb-events/300) (defining event); cases with it: [Cessna 182Q, 17 cases](https://openairdocs.org/ntsb-events/300/sequence.md?model=2072732), [All aircraft, 3,643 cases](https://openairdocs.org/ntsb-events/300/sequence.md) ## Analysis The pilot reported that, he performed a soft field takeoff on the wet grass airstrip. The airplane was just below rotation speed as he approached midfield and moments later the airplane lifted off momentarily, then settled back to the ground. The pilot chose to abort the takeoff just past midfield and applied braking action. The airplane did not have enough braking traction due to the wet surface and subsequently ran off the end of the airstrip, collided with a fence and came to rest nose first in a canal. The engine mount and firewall were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N735DU](https://openairdocs.org/aircraft/N735DU), registered now, S/N 18265349 (OpenAirDocs) - Reported make and model: CESSNA 182Q - Registry model: [Cessna 182Q](https://openairdocs.org/model/cessna-182q) (registry code 2072732) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18265349 - Year built: 1977 - Airframe hours: 3725.4 - Engines: Continental O-470-L/O-470-50 Northpoint XP470 235 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, November 1, 2021, 127 hours before - Departed: ID76, Donnelly, ID - Destination: Same as departure - Airport: ID76, Elk Ridge Airport, runway 27, 2,260 × 35 ft, grass/turf - Equipment: Electronic multifunction display, Handheld GPS, Onboard weather, Stall warning system, ADS-B, Auto-pilot, Electronic flight bag or handheld device ## 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.
