The instructor then told the pilot to perform a go-around. The pilot applied full power but was unable to control the airplane and decided to turn over the controls to the flight instructor. According to the pilot, the instructor was able to land safely after declaring an emergency. The stabilator, right wing and aileron were substantially damaged. ## Aircraft - Registration: [N2837X](https://openairdocs.org/aircraft/N2837X), registered now, S/N 17700237, built 1967 (OpenAirDocs) - Reported make and model: CESSNA 177 - Registry model: [Cessna 177](https://openairdocs.org/model/cessna-177) (registry code 2073704) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17700237 - Year built: 1967 - Engines: Lycoming O-360 180 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, April 6, 2022 - Airport: KDVT, Phoenix Deer Valley Airport, runway 25L, 8,196 × 100 ft, asphalt - Equipment: ADS-B ## Flight crew As NTSB recorded them.
