The pilot receiving instruction pushed the yoke forward to lift the tail, and the airplane veered to the left. The flight instructor assumed control of the airplane, “cut the power” and corrected with right rudder input. The airplane veered to the right and while he continued to apply corrective actions, the airplane collided with a taxiway sign. The airplane sustained substantial damage to the aft fuselage. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N2809N](https://openairdocs.org/aircraft/N2809N), registered now, S/N 13070, built 1947 (OpenAirDocs) - Reported make and model: CESSNA 140 - Registry model: [Cessna 140](https://openairdocs.org/model/cessna-140) (registry code 2071602) (OpenAirDocs) - Registry engine: [Continental C85 series](https://openairdocs.org/engine/continental-c85-series) (registry code 17008, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 13070 - Year built: 1947 - Airframe hours: 3643.7 - Engines: Continental motors C-85 85 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Kalabus Edward A Jr - Airworthiness certificate: Standard, Normal - Last inspection: Annual, January 6, 2022, 11.5 hours before - Destination: Same as departure - Airport: PRC, Prescott Rgnl - Ernest A Love Fld, runway 21R, 4,139 × 60 ft, asphalt - Equipment: Handheld GPS, ADS-B ## Flight crew As NTSB recorded them.
