Contractor will be responsible for the removal of internal and external piece part components to original design configuration. Below are ESTIMATE amounts annually: Fiscal Year Assets QTY FY 22 ~20-30 ea. hand FY 23 ~20-30 ea. hand FY 24 ~20-30 ea. hand FY 25 ~15-30 ea. hand FY 26 ~5-30 ea. hand MAJOR CHARACTERISTICS: Reference the following Assemblies: (see attached document for Figure 1: Center Section, Left side shown) Left: P/N 160D412000-17, NSN 1560-01-267-5423 Right: P/N 160D412000-18, NSN 1560-01-267-2365 The left and right nacelle center sections support the A-10 engines transfers thrust from engines to the aircraft. They contains two main frames, close out formers, intermediate formers between main frames, longitudinal closure members along the upper outboard edge and along the bottom inboard edge. The structure has inner and outer skin covers that form the outer fan duct wall and the nacelle basis contour line. Piano hinges run almost the entire length of the center section and are attached to the upper and lower longitudinal closures, and serve as a continuous attachment for the main engine access doors. The two main frames and engine link are machined from 7175-T73652 aluminum die forgings, and the formers and closures are built up from 7075-T6 clad aluminum alloy with the skin coverings of the same material. The piano hinges are machined from 7075-T7351 extrusion. The thrust fitting is made from SAE AMS-6526 steel forging. The two main frames, inboard closure fitting, thrust fitting, and the engine link are identified as Fracture/Fatigue Critical components. The Center Nacelles contains components that are classified as a Critical Safety Items (CSI) and contain Interchangeable/Replaceable (I&R) subcomponents. REPAIR OVERVIEW: Repairs will be based around a remove and replace concept and dependent on inspection criterial that will be provided in a Statement of Work. Contractor will be responsible for removing and replacing any component including all skins, formers, hanger frames, sub structure, and any components that fall outside of an acceptable condition and can be performed up to an acceptable economical cost threshold. Removal and replacement of internal and external components will be performed to drawing 160D412000, and other applicable technical data. Contractor will be responsible to review and validate that the repaired asset conforms to aircraft configuration per all technical data requirements. Tooling is required to maintain Interchangeable & Replaceable (I&R) features. Tooling to repair the assets however, is not available and the contractor will responsible to develop or procure their own tooling. The contractor's tooling concept and design are subject to review and approval by the Government. Part supportability is sparse and many of the formers, panels, and other repair piece parts will require in-house manufacturing per their applicable drawing specifications. The manufacturing of these components will require special production facilities that can facilitate forging, machining, sheet metal forming and chem-milling requirements. Several major components are made from forged aluminum or steel and require machining and heat treating operations. The need for special tooling may lead to long lead times that the contractor must address in their qualification statement. A more detailed inspection criteria and part replacement requirement will be provided in a Statement of Work upon contract solicitation. Contractor must be able to facilitate operations that allow for drilling, reaming, grinding, sanding and cutting of sheet metal components and installing rivets and fasteners. Contractor must also be capable of supporting non-destructive inspections, such as penetrant inspection and eddy current inspection.
