Safety record

Accident & incident history

2011-05-21 Incident · Peach Springs, AZ NTSB · ENG11IA032
Reported aircraft: Dehavilland DHC-6-300
Probable cause: A quality control failure in the Sungear, Inc. manufacturing and quality control process allowed sungears with surface finishes of the root fillet radius of the spline that did not conform to the drawing specifications to be released. The surface finish defect caused fatigue cracks to initiate early in the part life.
