The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N9621D](https://openairdocs.org/aircraft/N9621D), registered now, S/N 22-6532, built 1958 (OpenAirDocs) - Reported make and model: PIPER PA-22-160 - Registry model: [Piper PA-22-160](https://openairdocs.org/model/piper-pa-22-160) (registry code 7102214) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 22-6532 - Year built: 1958 - Airframe hours: 2198.8 - Engines: Lycoming O360-A4A 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Limitless Outdoors - Airworthiness certificate: Standard, Normal - Last inspection: Continuous airworthiness, August 7, 2024, 65.3 hours before - Departed: AK00, Anchor Point, AK - Equipment: ADS-B ## Flight crew As NTSB recorded them.
