The pilot initially reported that the takeoff seemed normal at first, but as it progressed it began to feel “sluggish.” When the airplane was about half to three-quarters of the way down the runway, he observed an indicated airspeed of 62 knots, and became concerned the airplane was not performing correctly. He elected to abort the takeoff, retarded the throttle and applied brakes. The airplane continued past the end of the runway, veered into grass, and impacted a perimeter fence, which resulted in substantial damage to the airplane’s left wing. A review of recovered data recorded by the onboard avionics showed that the airplane accelerated to an indicated airspeed of 85 knots before it began decelerating. The pilot, after reviewing the recorded avionics data, acknowledged that the engine developed full rated power throughout the takeoff roll, and that the airplane accelerated normally prior to the abort decision. He also reported that there was no glare that would have impacted his ability to observe the primary flight display’s airspeed indicator. The pilot also stated that there were no preimpact mechanical malfunctions or failures of the airplane that would have precluded normal operation. ## Aircraft - Registration: [N726EA](https://openairdocs.org/aircraft/N726EA), registered now, S/N E-3943, built 2010 (OpenAirDocs) - Reported make and model: HAWKER BEECHCRAFT CORP G36 - Registry model: [Hawker Beechcraft G36](https://openairdocs.org/model/hawker-beechcraft-g36) (registry code 4220009) (OpenAirDocs) - Registry engine: [Continental IO-550-B](https://openairdocs.org/engine/continental-io-550-b) (registry code 17208, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: E-3943 - Year built: 2010 - Airframe hours: 462.4 - Engines: Continental IO 550 B39B 300 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Utility; Standard, Normal - Last inspection: Annual, January 5, 2026, 0 hours before - Departed: DXR, Danbury, CT - Airport: DXR, Danbury Muni, runway 35, 3,135 × 100 ft, asphalt - Equipment: ADS-B, Stall warning system, Onboard weather, Electronic primary flight display, Electronic multifunction display, Auto-pilot ## 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.
