On February 9, 2015 at 0615 eastern standard time, N30EA, a DH6 Twin Otter sustained substantial damage when it collided with N70EA, another DH6 Twin Otter, during engine start at the Sebastian Municipal Airport (X26), Sebastian, Florida. Neither the pilot on N30EA or N70EA were injured. Both airplanes were registered to and operated by Eagle Air Transport, Ottawa, Illinois. An instrument flight rules flight plan was filed for the re-positioning flight that was destined for the Exuma International Airport (MYEF), George Town, Bahamas. Visual meteorological conditions prevailed for the positioning flight conducted under the provisions of 14 Code of Federal Regulations Part 91.

Both airplanes were parked right next to each other, wing-tip to wing-tip. N30AE was parked on the right side of N70AE. The pilot of N30AE stated that she had just started the engines. When she advanced the throttles (one at a time) to bring the generators on-line, the airplane began to move forward. She said she tried to apply the brakes, but they were not working and she was unable to move the tiller, which was positioned all the way to the left. The pilot was unable to stop the airplane and it collided with N70AE.

The pilot of N70AE said that had not started the engines yet when N30AE struck his airplane.

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. Read the NTSB...
