During the climb, the airplane impacted tall vegetation at the end of the airstrip. The left wing and horizontal stabilizer sustained substantial damage. The pilot stated that the airstrip was sloped upward in the direction of landing, and the temperature was very warm, which limited the airplane's performance. He stated that the accident may have been prevented if he had considered the go-around limitations before attempting to land. The pilot stated there were no preaccident mechanical malfunctions or anomalies that would have precluded normal operation. ## Aircraft - Registration: [N7208D](https://openairdocs.org/aircraft/N7208D), registered now, S/N 22-5032, built 1957 (OpenAirDocs) - Reported make and model: Piper PA22 (150) - Registry model: [Piper PA-22-150](https://openairdocs.org/model/piper-pa-22-150) (registry code 7102210) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 22-5032 - Year built: 1957 - Engines: Lycoming O-320 SERIES 150 hp reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Departed: BCV, Birchwood, AK - Destination: BCV, Birchwood, AK ## Flight crew As NTSB recorded them.
