The airplane had not been flown for about 5 years prior to the accident, and was undergoing maintenance in preparation of a ferry flight. A mechanic reported that he had asked the pilot to conduct some engine run-ups as close to full power as possible. The pilot taxied to runway 35, a 2,470 foot-long, 35 foot-wide, gravel and turf runway; where he performed two high speed engine run-ups.
The airplane was being used for sport parachute operations. During the initial climb after takeoff the right engine failed followed by the airplane’s slow descending right turn into wooded terrain. The airplane crashed through trees and caught on fire. The fire was extinguished prior to the destruction of the airplane.
During a skydiving operation, the aircraft was slowed to slow cruise flight for a parachute jump. As skydivers were moving to the exit door for a group jump, the d-ring of one skydiver’s reserve parachute became entangled on a protruding cabin door support bracket. The reserve chute deployed & was caught in the slip stream. The skydiver was then pulled from the open door. He impacted the right horizontal stabilizer, fell 4000 ft to the ground & was fatally injured. Most of the right stabilizer was torn from the aircraft. After its separation, the aircraft entered a dive & the remaining skydivers jumped from the plane.
