Confidence Rating: Accident investigation report completed and information captured
At 12,500 feet over the drop zone 16 parachutist exited the plane. Then the aircraft lost control and three jumpers hit the stabilizer. The aircraft crashed in a near vertical descent. Investigation revealed the centre of gravity was behind the aft limit for takeoff and the jump. The elevator trim actuator was found in a position for full nose-up trim.

PROBABLE CAUSE: "The failure of the operator and the pilot-in-command to assure proper load distribution during the jumper exit procedure. A more intensive program of surveillance by the Federal Aviation Administration may lead to the detection and elimination of some of the factors in the accident."
