• Main parachutes used for intentional jumping must be packed by the person jumping or by a U.S. certificated parachute rigger.
• The auxiliary parachute must be packed by a certificated and appropriately rated parachute rigger.
• If the parachute is made from synthetic materials, it must be packed within 120 days of its use. If it is made from materials subject to mold or mildew, then it must be packed within 60 days of use.
• If a main static line is used, it must meet certain requirements as to its use and configuration.
• An approved parachute is defined as a parachute manufactured under a type certificate or a Technical Standard Order (C-23 series), or a personnel-carrying U.S. military parachute (other than a high altitude, high speed, or ejection type) identified by a Navy Air Facility, an Army Air Field, and Air Force-Navy drawing number, an Army Air Field order number, or any military designation or specification number.
