SOL_Attach_14_TERMS OF AGREEMENT (TOA).xlsx

This is a Terms of Agreement (ToA) spreadsheet that details specific components and subassemblies required for the T56 Series 3.0/-15 and 3.5/-15A engine repair and overhaul contract. The document specifies work breakdown structure (WS) items, contract line item numbers (CLIN), National Stock Numbers (NSN), component nomenclature, engineering release and revision codes (ERRC), source of supply (SOS), budget codes, and authorized requisition quantities across multiple engine modules including ADH Assembly, Compressor Module, RGB (Reverse Gear Box), and Turbine Module. Each component entry includes a replacement rate percentage and authorized quantity, with replacement rates ranging from 1% to 100% and authorized quantities varying from 1 to 360 units depending on the part type.

The ToA covers a comprehensive list of engine components critical to T56 engine sustainment operations, including major assemblies such as turbine vane cases, turbine wheels across multiple stages, compressor housings, gear boxes, and various seals and supports. Components are coded with budget code "T" and SOS designation "FHZ" with quantity-per-assembly (QPA) values of 1, 2, 6, or 12. Notable high-volume requirements include Vane Segment Assemblies for turbine stages (180-360 units authorized) and the Propeller Shaft with a 23% replacement rate and 65 authorized units. This ToA serves as the baseline supply and component requirement document supporting the Air Force Sustainment Center's indefinite delivery, indefinite quantity contract for T56 engine repair and overhaul across USAF, USN, and Foreign Military Sales customers.
