The pilot reported that he then taxied to the end of the grass runway, held the yoke in the full aft position, and applied full throttle to perform a soft-field takeoff. The pilot stated that while rolling down the runway, he experienced pitching and bouncing of the airplane. At an airspeed of 60 mph, he began to relieve the yoke back pressure, expecting the airplane to begin to liftoff; however, the airplane remained on the runway at 70 mph. At this point, the pilot elected to abort the takeoff and he brought the engine throttle to idle, then applied brake pressure to both brakes, but the airplane began to skid. The airplane continued past the end of the runway, and impacted vegetation and a wire fence. The pilot reported there were no mechanical malfunctions or failures that would have precluded normal operation. A postaccident examination of the airplane revealed it had sustained substantial damage to the left wing and the fuselage. A photograph taken of the airplane shortly after the accident revealed that the flaps were in the retracted position. According to the airplane’s Pilot’s Operating Handbook, “Soft field takeoffs are performed with 20° of flaps.” Additionally, according to the FAA Airplane Flying Handbook, for a soft field takeoff, the pilot should lower the wing flaps prior to starting the takeoff to provide additional lift and to transfer the airplane’s weight from the wheels to the wings as early as possible. It is likely, that due to the flaps being retracted, the rough grass conditions resulted in additional drag on the wheels, preventing the airplane from accelerating sufficiently for flight. ## Aircraft - Registration: [N691DM](https://openairdocs.org/aircraft/N691DM), registered now, S/N 18263984, built 1975 (OpenAirDocs) - Reported make and model: CESSNA 182 (P) - Registry model: [Cessna 182P](https://openairdocs.org/model/cessna-182p) (registry code 2075816) (OpenAirDocs) - Registry engine: [Continental O-470R](https://openairdocs.org/engine/continental-o-470r) (registry code 17071, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18263984 - Year built: 1975 - Airframe hours: 6598.1 - Engines: Continental Aerospace Technologies O-470-S1B 230 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 21, 2025, 72 hours before - Destination: HFD, Hartford, CT - Airport: 1B2, Katama Airpark, runway 06, 2,700 × 50 ft, grass/turf - Equipment: Auto-pilot, Stall warning system, Electronic multifunction display ## 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.
