On 28 October 2013 a BAe Jetstream 31 crew failed to release one of the propellers from its starting latch prior to setting take-off power and the aircraft immediately veered sharply off the side of the runway without directional control until the power levers were returned to idle. The aircraft was then steered on the grass towards the nearby apron and stopped. The Investigation found that the pilots had habitually used multiple unofficial procedures to determine propeller status prior to take-off and also noted that no attempt had been made to stop the aircraft using the brakes.
