While taxiing for takeoff he performed a check of the flight controls, adding there were no discrepancies and the gust lock was free. He initiated takeoff, and when the flight was 20 ft above the runway, he noted the airplane was right wing low. He applied left aileron control input but noted the control did not move. He then also applied right aileron control input, but it wouldn’t move to the right either. He aborted the takeoff and thought about dumping the load of chemical but did not. The airplane touched down on the grass portion of his runway and bounced three times. On the third bounce he reported both main landing gear collapsed. The airplane slid into the nearby field and came to rest upright. Postaccident examination of the airplane revealed substantial damage to both wings and the bottom of the fuselage. Examination of the flight control system was unable to identify any obstructions or other issues. ## Aircraft - Registration: [N4032L](https://openairdocs.org/aircraft/N4032L), registered now, S/N T34-264, built 1999 (OpenAirDocs) - Reported make and model: Ayres S2R (T34) - Registry model: [Ayres S2R-T34](https://openairdocs.org/model/ayres-s2r-t34) (registry code 0970106) (OpenAirDocs) - Registry engine: [Pratt & Whitney Canada PT6A-45](https://openairdocs.org/engine/pratt-whitney-canada-pt6a-45) (registry code 52105, turbo-prop) (OpenAirDocs) - Category: Airplane - Serial number: T34-264 - Year built: 1999 - Airframe hours: 9709.9 - Engines: Pratt & Whitney PT6A-34AG 750 horsepower turbo prop - Damage: Substantial damage - Flight: Aerial application, Part 137 - Airworthiness certificate: Special, Restricted (Special) - Last inspection: Annual, March 20, 2020, 130 hours before - Airport: None, Private, runway 17, 2,845 × 20 ft, grass/turf - Equipment: Handheld GPS ## 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
