## NTSB investigations (4)

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 ANC11FA091](https://openairdocs.org/ntsb/ANC11FA091), Sep 2, 2011: Cessna 208B (N207DR), Nightmute, AK, destroyed, 1 fatal. Probable cause: The failure of the pilot of the other airplane to maintain adequate clearance while performing an unexpected and unannounced abrupt maneuver, resulting in a midair collision between the two airplanes.
- [NTSB ANC10LA019](https://openairdocs.org/ntsb/ANC10LA019), Feb 17, 2010: Cessna 208B (N207DR), Kwigillingok, AK, substantial damage. Probable cause: The pilot's decision to take off with ice-contaminated wings in freezing rain and mist, which resulted in an aerodynamic stall.
- [NTSB ERA09LA269](https://openairdocs.org/ntsb/ERA09LA269), Apr 21, 2009: Cessna 208 (N208JW), Frederick, MD, substantial damage. Probable cause: A loss of engine power due to the failure of one or more compressor turbine blades for an undetermined reason.
- [NTSB ANC97LA109](https://openairdocs.org/ntsb/ANC97LA109), Jul 22, 1997: Cessna 208 (N9481F), Naknek, AK, substantial damage. Probable cause: The pilots decision to continue the landing into adverse weather conditions and failure to maintain runway alignmet. A factor was the rain shower which resulted in reduced forward visibility.

## FAA accident and incident reports (6)

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft 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.
