Two de Havilland Canada DHC-6 Twin Otter aircraft, N30EA and N70EA were both parked right next to each other, wing-tip to wing-tip at Sebastian Municipal Airport, Florida. N30AE was parked on the right side of N70AE.
Both aircraft were planning to conduct a re-positioning flight that was destined for the Exuma International Airport, Bahamas.
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. At that moment, 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.

Probable Cause:

PROBABLE CAUSE: "The pilot's failure to conduct all of the required items on the Before Starting Engines checklist, which resulted in her failure to detect an open hydraulic circuit breaker and led to insufficient hydraulic pressure to operate the airplane's brakes, her subsequent loss of airplane control, and ground collision with an airplane."
