## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

SHORTLY AFTER TAKEOFF, THE AIRCRAFT EXPERIENCED SEVERE VIBRATION AND A LOSS OF POWER. PILOT WAS UNAWARE OF THE FIRE AND MADE A 180 TURN TO RETURN TO THE AIRPORT AND LANDED WITHOUT INCIDENT. GROUND PERSONNEL EXTINGUISHED THE FIRE.  THE PROPELLER HUB HAD FAILED AND  ONE PROP BLADE HAD DEPARTED THE AIRCRAFT. THIS CAUSED EXCESSIVE VIBRATION WHICH RESULTED IN A FUEL LINE FAILURE WHICH CAUSED THE IN-FLIGHT FIRE. THE SEPARATED PROP BLADE ALSO CONTACTED ONE OF THE MAIN ROTORS.

## The NTSB's investigation of this event (1)

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.

Probable cause: The fracture of the propeller hub due to corrosion pitting along the propeller blade root seat, which led to cracking that was propagated due to high-cycle fatigue.
