## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Airframe/component/system failure/malfunction, landing - flare/touchdown
  - propeller system/accessories,blade - fatigue (cause)
  - propeller system/accessories,blade - separation (cause)

## Analysis

VIBRATION WAS EXPERIENCED SHORTLY AFTER TOUCHDOWN CAUSED BY THE FAILURE OF THE PROPELLER BLADE AS A RESULT OF FATIGUE CRACKING WHICH WAS INITIATED FROM A LINEAR AREA IN A DEFECT FREE PORTION OF THE CAMBER FACE OF THE BLADE. PROPAGATION WAS THROUGH 60% OF THE BLADE CROSS SECTION BEFORE FINAL FAILURE. THE PROP BLADE HAD SEPARATED 23 INCHES FROM THE TIP AND DEFLECTED OFF THE RWY AWAY FROM THE FUSELAGE.
