## Narrative

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

JUNE 4, 2015 APPROXIMATELY 1230 ALASKA DAYLIGHT TIME, A DE HAVILLAND DHC-3 EQUIPPED WITH A HONEYWELL TPE331 TURBINE ENGINE, EXPERIENCED A VIBRATION DURING CRUISE FLIGHT IN THE VICINITY OF SKWENTNA, ALAKSA. THE AIRMAN RETURNED TO ANCHORAGE AND LANDED WITHOUT INCIDENT. THE AIRMAN EXAMINED THE AIRPLANE AND FOUND THE SKIN ON THE RIGHT ELVEVATOR SERVO TAB WAS FRACTURED AND THE SPAR STRUCTURES INSIDE THE RIGHT ELEVATOR WERE CRACKED.

## 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 flutter failure of the right elevator servo tab due to the improper fabrication of the servo tab and maintenance personnel’s subsequent failure to detect anomalies with the servo tab.
