Aircraft involved
Probable cause & findings
THE SHROUD LINES FROM THE PARACHUTE CUTTING THROUGH THE LEFT HORIZONTAL STABILIZER AND DEFORMING THE LEFT ELEVATOR AFTER THE JUMPER HAD AN UNCOMMANDED DEPLOYMENT OF HIS RESERVE PARACHUTE AND WAS PULLED FROM THE AIRPLANE.
Factual narrative
AS THE JUMPMASTER AND STUDENT JUMPER BACKED INTO THE DOOR OF THE AIRPLANE IN PREPARATION FOR A TANDEM JUMP, HE HAD A UNCOMMANDED DEPLOYMENT OF HIS RESERVE PARACHUTE, THAT DRAGGED THEM OUT THE DOOR. THE JUMPERS WENT UNDER THE LEFT HORIZONTAL STABILIZER WHILE THE CANOPY WENT OVER THE TOP. AFTER A FEW SECONDS, THE PARACHUTE SHROUD LINES CUT THROUGH THE HORIZONTAL STABILIZER AND DEFORMED THE LEFT ELEVATOR. THE TANDEM JUMPERS FELL FREE, CUT AWAY THE DAMAGED RESERVE PARACHUTE, AND DEPLOYED THE MAIN CANOPY. THE AIRPLANE LANDED WITHOUT FURTHER DAMAGE. A WITNESS SAW THE PILOT CHUTE FOR THE RESERVE PARACHUTE DEPLOY AS THE JUMPER BACKED INTO THE DOOR. HE SAID THE PARACHUTE WAS SECURE WHEN HE OBSERVED IT A FEW SECONDS PRIOR TO THE JUMP.
