About this file
This document is a parts list for gas turbine engine components, organized by National Stock Number (NSN), Ordnance Part Number, nomenclature, and average monthly demand. The list contains approximately 180 line items representing various engine parts including housings, bearings, vanes, rotors, turbines, seals, valves, and associated assemblies. Average monthly demands range from 2.25 units to 855 units, with the highest demand items being the Vane and Lever Assembly IG (855 units), Reduced Head Bolt (540 units), and Sleeve-Chafing (630 units). Several items are marked as N/A or #N/A for demand quantities, indicating either incomplete data or parts of larger modification kits and assemblies.
The components appear to support military aircraft propulsion system maintenance and operations, featuring parts such as compressor stages (HPC, LPC), turbine sections (HPT, LPT), combustor liners, fuel system components, and associated hardware. Many parts reference NSN designations from federal supply classes including 2835 (aircraft turbine engine parts), 3040 (mechanical transmission components), 4720-4810 (hose and valve assemblies), and 5340-5365 (mechanical fasteners and hardware). The document does not specify contract vehicles, award dates, response dates, or pricing information, appearing instead as a requirements or inventory management document rather than a formal solicitation or contract document.
