## 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.
