Parachutes

1. Scope and Applicability

This PCR governs foreground manufacturing data packages for finished parachutes and factory-complete parachute assemblies classified as CPC 3.0 code 27170. It covers personnel, emergency, reserve, cargo, extraction, deceleration, and drogue configurations only when the data package declares the actual product type and configuration. The foreground starts with qualified purchased materials and components at the manufacturing site and ends with a released, packed factory-gate product.

The PCR does not cover paragliders, kites, sails, tents, parachute-operation services, repacking or maintenance services, or fabric, cord, webbing, harness, container, and hardware components sold under a separate product identity. It does not authorize averaging unlike parachute types or material systems without traceable production records.
