Circumstances
During a parachute jump, a parachutist was climbing out onto the aircraft's strut. Her pilot chute became caught on a safety belt, resulting in the inadvertent deployment of her main parachute.
Sequence of Events
The main parachute deployed and streamed back over the right horizontal stabilizer. The parachutist went under the stabilizer as the parachute passed over the top. The parachute lines subsequently damaged the right horizontal stabilizer and elevator.
Actions Taken
The parachutist cut the parachute line, releasing herself and the chute from the aircraft. She then landed uneventfully using her reserve parachute.
Aftermath
The pilot executed a normal landing at the departure airport following a slow descent from an altitude of 10,000 feet.
