Incident Overview
A charter flight operating between Malcolm Island and Duluth experienced a runway excursion during takeoff. The aircraft was carrying 25 occupants, all of whom evacuated safely. The aircraft sustained damage that rendered it beyond repair.
Sequence of Events
The crew expedited the takeoff procedure to clear the runway for an incoming aircraft scheduled to land. During the takeoff roll, at a speed of 60 to 70 knots, the airplane began to swerve. The swerving continued for approximately 1,500 feet before the aircraft veered off the runway and came to a halt.
Probable Cause
Investigators determined that the loss of control was caused by some locks not being removed before the flight.
