From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

At approximately 2:30 AKDT, a PA-18-150 landing at Troy airstrip in Wasilla, sustained substantial damage due to loss of control which resulted in the aircraft flipping over.

The aircraft came to rest in a flip-over event 135 feet after the initial veer-off the grass runway in a swampy and shallow body of water. The pilot stated to the NTSB investigator via telephone that he was landing at the private airstrip, for reason unknown at this point, and lost control of the aircraft toward the end of the runway. The aircraft came to rest three quarters down the usable length of the runway.

The prop and prop spinner had virtually no damage or indications of rotation upon impact.

The aircrafts GPS was located and retrieved with tracks indicating the pilot made several areal orbits before landing.

There was excessive amounts of 100LL avgas in the swampy water around the aircraft suggesting this aircraft accident was not led to by fuel exhaustion. First responders turned off the master switch. The inspector, with informing the NTSB, turned the fuel valve to the off position. The aircraft did not appear to be equipped with an ELT. There was minor damage to the aircraft caused by the first responders in the extraction process primarily around the cockpit glass area.

An interview by the FAA with the pilot did not occur at the scene due to the individual undergoing hospitalization.

Research in FAA databases revealed pilot's medical was denied back in 2010. Iacw 2150.3, operating with a denied medical warrants revocation . Eir process initiated.
