He slowly pushed the control stick forward, added power to bring the tail up, and the airplane started to drift to the left. By the time he was able to react, the left tire caught the edge of the runway, and the airplane drifted into a fence. The pilot stated that he was riding the left brake when power was applied and did not remove his foot fully off the brake before the takeoff roll. Both wings, fuselage, and the empennage sustained substantial damage. The pilot stated that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N45TW](https://openairdocs.org/aircraft/N45TW), registered now, S/N JA512-11-17, built 2021 (OpenAirDocs) - Reported make and model: JUST SUPERSTOL - Registry model: [Cameron Clark S JA30 SUPERSTOL](https://openairdocs.org/model/cameron-clark-s-ja30-superstol) (registry code 05640EG) (OpenAirDocs) - Registry engine: [Yamaha ALL MDLS A/B](https://openairdocs.org/engine/yamaha-all-mdls-a-b) (registry code 80000, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: JA512-11-17 - Year built: 2021 - Engines: Edge Performance Yamaha APEX 162 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Condition, January 25, 2025, 0 hours before - Destination: Same as departure - Airport: 7V2, North Fork Valley, runway 24, 4,500 × 60 ft, asphalt - Equipment: Electronic primary flight display, ADS-B, Angle of attack indicator, Auto-pilot, Electronic flight bag or handheld device ## Flight crew As NTSB recorded them.
