## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19770120001649A](https://openairdocs.org/incident/19770120001649A), Jan 20, 1977: Blanca 11AC, Harrah, WA, Substantial damage. Descended into fog. Pulled up to avoid an object.

## Other investigations on N9791E (2)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

- [NTSB GAA16CA410](https://openairdocs.org/ntsb/GAA16CA410), Jul 26, 2016: Aeronca 11AC (N9791E), Gig Harbor, WA, substantial damage. Probable cause: The pilot's failure to maintain directional control during landing, and subsequent wing tip strike, which resulted in substantial damage to the rear spar.

Probable cause: The student pilot's improper application of rudder resulted in a loss of control during the landing roll and the flight instructor's inadequate oversight.
