Aviation accident WPR15FA125

The pilot’s initiation of an early rotation during takeoff, which led to an aerodynamic stall and loss of airplane control. Contributing to the accident were the pilot's use of noseup pitch trim and the operator's policy to use nose-up pitch trim during takeoff and the lack of oversight of the operator by the US Air Force. Contributing to the severity of the accident were US Marine Corps airport policies that allowed construction activities immediately adjacent to an active runway, which resulted in the airplane's collision with a truck.
