Analysis

The plt of the Grumman ag cat allowed 2 parachutists to board the resticted catagory acft for a parachute jumping flt. Each parachutist was positioned on a wing with his arm crooked around the respective wing center strut. After takeoff, the parachutist on the rgt wing fell off & plunged to his death. An exam of his chutes revealed that the main chute had barely started to open & the reserve chute was not deployed. Witnesses believed that the parachutist fell from about 400 to 500 ft AGL. Witness testimony & a post mortem exam of the deceased revealed that his rgt arm was weaker than his left arm due to a previous injury & surgery. The owner of the acft was not aware of, nor did he approve of, the use of the acft for parachute jumping.
