He then attempted a go-around by applying full engine power and removing carburetor heat. The airplane did not climb, bounced off the terrain, and impacted a stand of trees. The airplane sustained substantial damage to the wings, fuselage, and empennage. The student pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. At the time of the accident, the student pilot was landing the airplane on runway 27 with wind from 330° at 5 knots (kts) and wind gusts greater than 10 kts. ## Aircraft - Registration: [N30433](https://openairdocs.org/aircraft/N30433), registered now, S/N 17701251, built 1968 (OpenAirDocs) - Reported make and model: CESSNA 177A - Registry model: [Cessna 177A](https://openairdocs.org/model/cessna-177a) (registry code 2073706) (OpenAirDocs) - Registry engine: [Lycoming O&VO-360 series](https://openairdocs.org/engine/lycoming-o-vo-360-series) (registry code 41514, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17701251 - Year built: 1968 - Airframe hours: 4748 - Engines: Lycoming O-360-A2F 180 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, October 19, 2023 - Destination: Same as departure - Airport: 88C, Palmyra Muni, runway 09/27, 2,800 × 200 ft, grass/turf - Equipment: Electronic primary flight display, Electronic multifunction display, Auto-pilot, ADS-B, Stall warning system, Onboard weather ## Flight crew As NTSB recorded them.
