AC 105-2E— Sport Parachuting

  1. PARACHUTE PACKING
    1. Reserve Parachutes.
      1. A certificated and appropriately rated parachute rigger must pack the reserve parachute.
      2. Visiting foreign parachutists jumping parachute systems that the FAA has not approved must have their reserve parachutes packed by someone acceptable to the foreign parachutist's Civil Aviation Authority (CAA) or by a FAA-certificated rigger.
      3. The certificated and appropriately rated parachute rigger must pack the reserve parachute within 180 days before the date of use if the parachute system is made of materials substantially resistant to mold, mildew, or other rotting agents, or within 60 days of the date of use otherwise.
      4. A parachute user must ensure that an AAD is maintained in accordance with the AAD manufacturer's instructions and service requirements. When a rigger packs a reserve parachute, the rigger is only certifying that it meets all safety requirements on the day it is packed; therefore, riggers should note any maintenance or battery replacement due date(s) on the packing data card so that users are able to determine AAD airworthiness and ensure conformance to the regulations. AADs are to be installed in accordance with the harness/container manufacturer's instructions.
      5. Only the rigger who did the packing, and whose seal is removed to permit scheduled or unscheduled maintenance or repairs to the reserve container, may open, reclose, and reseal it (e.g., AAD service or closing loop adjustment) within the 180-day or 60-day period in subparagraph 14a(3).
    2. Main Parachutes. Main parachutes must be packed within 180 days before the date of use and be packed by any certificated parachute rigger or a person working under the direct supervision of a certificated parachute rigger. The person making the next jump (including a tandem parachutist in command, but not the passenger parachutist) may also pack the main parachute.

Sec. 105.43 Use of single-harness, dual-parachute systems

No person may conduct a parachute operation using a single-harness, dual-parachute system, and no pilot in command of an aircraft may allow any person to conduct a parachute operation from that aircraft using a single-harness, dual-parachute system, unless that system has at least one main parachute, one approved reserve parachute, and one approved single person harness and container that are packed as follows:

  1. The main parachute must have been packed within 180 days before the date of its use by a certificated parachute rigger, the person making the next jump with that parachute, or a non-certificated person under the direct supervision of a certificated parachute rigger.
  2. The reserve parachute must have been packed by a certificated parachute rigger—
    1. Within 180 days before the date of its use, if its canopy, shroud, and harness are composed exclusively of nylon, rayon, or similar synthetic fiber or material that is substantially resistant to damage from mold, mildew, and other fungi, and other rotting agents propagated in a moist environment; or
    2. Within 60 days before the date of its use, if it is composed of any amount of silk, pongee, or other natural fiber, or material not specified in paragraph (b)(1) of this section.
  3. If installed, the automatic activation device must be maintained in accordance with manufacturer instructions for that automatic activation device.
