NTSB aviation accident and incident investigations since 1962: the probable cause, findings, aircraft, crew, weather and docket of each, linked to the FAA registry and the FAA’s own reports.

## Latest cases

- [NTSB NYC99LA202](https://openairdocs.org/ntsb/NYC99LA202.md): Mooney M20E · Prattsburg, NY · Accident · Serious injuries · Limited investigation · Final report · Aug 15, 1999 · N3243F · Destroyed
  > Propeller blade separation, resulting from fatigue cracking initiated by intergranular corrosion. A factor was the lack of propeller blade corrosion inspection requirements.
