He stated that the airplane got too low on the approach and descended into the soybean crop off the approach end of the runway. The airplane impacted the end of the airstrip and the landing gear collapsed. He stated that everything on the airplane was operating normally and that the accident resulted from pilot error by coming in too low and allowing the airplane to contact the soybean crop. The airplane sustained substantial damage to the fuselage near the landing gear mounting area. ## Aircraft - Registration: [N393KW](https://openairdocs.org/aircraft/N393KW), registered now, S/N T34-267, built 1999 (OpenAirDocs) - Reported make and model: AYRES CORPORATION S2R-T34 - Registry model: [Ayres S2R-T34](https://openairdocs.org/model/ayres-s2r-t34) (registry code 0970106) (OpenAirDocs) - Registry engine: [Pratt & Whitney Canada PT6A-42](https://openairdocs.org/engine/pratt-whitney-canada-pt6a-42) (registry code 52062, turbo-prop) (OpenAirDocs) - Category: Airplane - Serial number: T34-267 - Year built: 1999 - Engines: Pratt & Whitney PT6A34AG 750 horsepower turbo prop - Damage: Substantial damage - Flight: Aerial application, Part 137 - Operator: Hoppe Air LLC, doing business as Hoppe Air, LLC - Registered owner: Hoppe Air LLC - Airworthiness certificate: Special, Restricted (Special) - Airport: 36IA, Tonner Fld, runway 18/36, 2,500 × 120 ft, grass/turf ## Flight crew As NTSB recorded them.
