The Commission recommends that the Director of Civil Aviation as a matter of urgency alerts all pilots and operators using the Fletcher FU24-954 aircraft for parachuting operations that when loaded with 6 or more passengers it is possible for the aircraft CG to be aft of the allowable limit, and that this could result in control difficulties, and that parachutists should be seated in the forward cabin area, preferably restrained to prevent them inadvertently moving rearward.
