The pilot lost directional control of the airplane and subsequently nosed over and came to rest inverted resulting in substantial damage to the wings, lift struts, rudder, and vertical and horizontal stabilizers. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N307AM](https://openairdocs.org/aircraft/N307AM), registered now, S/N 2403 (OpenAirDocs) - Reported make and model: AVIAT A1 (B) - Registry model: [Aviat A-1B](https://openairdocs.org/model/aviat-a-1b) (registry code 2210406) (OpenAirDocs) - Category: Airplane - Serial number: 2403 - Year built: 2007 - Engines: Lycoming O-360 A1P 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, April 15, 2024, 66 hours before - Departed: PAMR, Anchorage, AK - Destination: Seward, AK - Equipment: Satellite tracking device, Handheld GPS, ADS-B ## Flight crew As NTSB recorded them.
