# 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.

| How much | 1 kg net unpackaged product mass |
| How well | Released against the declared specification, inspection plan, functional tests, and applicable certification or standard |
| How long or cycle | One released production lot normalized to 1 kg; declared service-life or removal limitations are metadata and do not change the reference amount |

| downstream_use | Input to reviewed `process` and `lifecyclemodel` projections and to product LCI/LCA studies |
| allowed_use | Product-specific or configuration-family studies when scope, material system, operating limitations, geography, period, and allocation basis match the declared dataset |
| excluded_use | Unqualified category-wide averages; substitution across unlike parachute types or material systems; service, maintenance, use, or end-of-life claims outside the declared boundary |
| required_metadata | PCR id; CPC code; reference UUID; product type and configuration; material specifications; included components; operating and service-life limitations; certification or standard; inspection and test basis; site; geography; period; boundary; allocation; packaging basis |
| required_quality_disclosure | Primary-data coverage; meter and scale calibration; supplier dataset representativeness; UUID gaps; temporal mismatches; allocation shares; mass-balance residuals; excluded operations; route-specific absent exchanges |
| update_trigger | Change in product type, canopy geometry, material or coating system, suspension-line or hardware configuration, included assembly, manufacturing route, site, supply mix, certification basis, or production-period representativeness |
