The pilot attempted to correct the veer and applied brakes; however, the airplane nosed over and came to rest inverted, which resulted in substantial damage to the left wing strut. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N9697P](https://openairdocs.org/aircraft/N9697P), registered now, S/N 18-7509040, built 1975 (OpenAirDocs) - Reported make and model: PIPER PA18 (150) - Registry model: [Piper PA-18-150](https://openairdocs.org/model/piper-pa-18-150) (registry code 7101828) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18-7509040 - Year built: 1975 - Engines: Lycoming O-320 160 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Departed: PALH, Anchorage, AK - Destination: Same as departure - Airport: Z40, Goose Bay, runway 08/26, 3,000 × 75 ft, gravel - Equipment: Handheld GPS ## Flight crew As NTSB recorded them.
