Aircraft launching gear; deck-arrestor or similar gear; ground flying trainers

1. Scope and Applicability

This PCR applies to factory-gate production of a complete, acceptance-tested item of aircraft launching gear, deck or runway arresting gear, similar aircraft launch/recovery gear, or a ground-based flight training device. It covers the configuration delivered under one purchase or production order, including manufacturer-controlled fabrication, treatment, assembly, software configuration, functional testing, and delivery preparation.

The category includes steam or electromagnetic launching equipment and controls, arresting engines and controls, shore-based arresting systems, and ground flight simulators or flight training devices. Product family, qualification basis, performance class, installed options, net mass, and packaged mass must be declared. The NAVSEA fleet-maintenance manual substantiates the launch/recovery equipment boundary and quality-assurance performance verification; the U.S. Navy operational report documents representative ashore and shipboard functional testing; FAA Part 60 substantiates objective and subjective qualification of flight training devices (navsea-jfmm-alre-2024, us-navy-ford-alre-test-2017, faa-part-60-fstd).

Aircraft and spacecraft engines, complete aircraft, ship or airfield civil works, carrier or runway structures, training services, site installation, use, maintenance, and end-of-life are excluded. Upstream production of purchased materials, components, electricity, fuels, and chemicals is represented by linked supplier datasets rather than duplicated in the foreground.

Waste flows

Elementary flows

Any additional material, component, utility, packaging component, waste, or direct emission that crosses a foreground process boundary and is not listed above must be added to the produced dataset as its own chemically or physically specific atomic row. It must not be folded into a plural “other materials,” “utilities,” or “wastes” row.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_subdivide_first	shared production and test operations	Avoid allocation by separately metering or physically disaggregating work orders, process time, energy, material issues, tests, and waste for the declared reference configuration.
allocation_shared_facility	unavoidable shared facility burdens	When subdivision is not feasible, allocate by a documented physical driver that caused the burden, such as machine-hours weighted by rated load, treated surface area, measured mass throughput, or test power-time; do not use revenue unless no defensible physical relationship exists.
allocation_scrap	recovered metal and packaging	Report recovered material as a separate waste or secondary-material output and do not credit avoided primary production inside the foreground inventory; any recycling allocation is applied consistently in the downstream study and disclosed.
allocation_rework	rejected or reworked units	Assign rework and failed-test burdens to the accepted output of the same reporting period using traceable work-order records; disclose exceptional prototype or development burdens rather than silently averaging them into serial production.
