2019 Cedartown Collisions Other DHC-6 Twin Otter GA Non-Fatal Multi-Engine

DHC-6 Twin Otter Non-Fatal Cedartown, GA October 11, 2019

The pilot in the landing airplane reported that, he had turned on the airport runway pilot-controlled lighting about 5 miles prior to arriving at the airport, and transmitted 2-mile final radio call, over the airport’s CTAF. He landed the airplane and made “S” turns on runway 28 because, “it is not possible to see the opposite threshold” when established on the runway. When the pilot began a right turn to exit the runway at the mid-field taxiway, an airplane that had initiated a takeoff roll from the opposite end of the runway collided with the landing airplane. The airport’s runway does not have a parallel taxiway and it is standard practice to back taxi to the departure end.

1990 DHC-6 Twin Otter Improper/Poor Maintenance Non-Fatal Non-Fatal Multi-Engine

DHC-6 Non-Fatal Perris Valley, CA December 9, 1990

After lift-off, at about 100 ft agl and 85 kts, the left eng decelerated and the airplane began to yaw and roll left. The pic aborted the takeoff, turned left and landed on a flat level field. The airplane struck a fence, then trees. Examination of the left eng revealed the loss of power was attributed to a fatigue fracture of a compressor turbine blade, which led to subsequent blade fractures. The right eng was examined and found to have advance wear on the throttle cam assembly of the power turbine governor. In a test cell, only aprx 28% of takeoff power could be achieved. The cam lobe wear had progressed over an extended period of time. The right engine prop governor was replaced 11/18/90, followed by a test run.
