SYNOPSIS- C-5 Aft Center Cargo Door "C" Models

Statement of Objectives (SOO)

This document outlines the objectives for the overhaul of the MC Aft Center Cargo Door, LHS (Part Number: 4F69010-101A, NSN: 01-296-6316).

Part A: Teardown and Inspection

• Prepare a Teardown and Inspection Report (CDRL A005).
• Inspect per Lockheed Drawing 4F69010 and applicable sub-assembly drawings.
• Identify part number via data plate photo; notify if not -101A.
• List any missing or extraneous parts.
• Determine proposed repairs, including repair by replacement or repair per Technical Orders (T.O.s).
• For damage outside T.O. limits, contact AFLCMC/WLSEBA via AFMC Form 202.
• List defects and repair scenarios, including visual inspection (excluding honeycomb panels).
• Perform detailed visual inspection (DVI) of the door and machined fittings per T.O. 1C-5M-3.
• Evaluate and repair corrosion damage per Lockheed drawing 4F69010 and T.O. 1C-5M-23.
• Record all discrepancies on a log sheet and mark them on the part with a red marker.
• If the shipping container is unsuitable, manufacture a new one (ref: PWS, section 4.3.10.4).
• Manufacture and install IUID marking if not present (ref: PWS section 4.3.11).

Part B: Technical References for Overhaul

• Create and submit a 3D "as-designed" model of the door (CDRL A007).
• Develop and present a simplified overhaul manual (CDRL A006).
• Use Lockheed drawing 4F69010-101A and other sub-tier drawings.
• Add a quarter inch trim to exterior/perimeter skins/edges, except for the inboard edge.
• Reference various Technical Orders (T.O.s) for specific procedures (e.g., corrosion control, NDI, structural repair).
• Submit repair needs outside T.O. limits to AFLCMC/WLSEBA via AFMC Form 202.

Part C: First Unit Repair Verification (FURV) Requirements

• Provide documentation of repairs and special authorizations.
• Include material analysis and process certifications.
• Submit a Supplier Quality inspection report.
• Provide photo documentation of data plates (overhaul and IUID).
• Create an "as-manufactured" 3D model and conduct CAD compare analysis against the "as-designed" model (CDRL A007).
• Report deviations exceeding 0.1 inches to AFLCMC/WLSEBA via AFMC Form 202.
• Submit documents, certifications, and results as a FURV Test Report per CDRL A008.

Not explicitly stated, but implied to be a depot-level overhaul.

• Shipping paperwork, crate markings, and inventory tags may be erroneous; the data plate is the authoritative source for part number identification.
• The government may provide a similar, but different, NSN/part number carcass that needs to be inducted and returned as the required NSN/part number.
• An approved, redesigned Legacy Special Packaging Instruction (SPI) is not available at this time.
• The government lacks 3D models and an overhaul manual for this item, requiring the contractor to develop them.

Statement of Work (SOW) / Performance Work Statement (PWS)

This Statement of Objectives (SOO) outlines the requirements for the overhaul of the MC Aft Center Cargo Door, RHS (Part Number: 4F69010-102A, NSN: 01-297-9975).

• Teardown and Inspection: Includes preparing a report, inspecting per Lockheed Drawing 4F69010 and applicable sub-assembly drawings, identifying the part number via data plate, listing missing or extraneous parts, and determining proposed repair methods.
• Detailed Inspection: Perform visual inspections (DVI) per Technical Order (T.O.) 1C-5M-3, paying close attention to fasteners, fittings, wear, corrosion, and damage. Honeycomb skin panels are 100% replacement parts and are not to be inspected for repair.
• Repair: Evaluate and repair corrosion damage, including plating requirements per Lockheed drawing 4F69010 and T.O. 1C-5M-23. Repairs outside of Technical Order limits must be submitted to AFLCMC/WLSEBA via AFMC Form 202 for engineering disposition.
• Deliverables: Includes a "Teardown and Inspection Report" (CDRL A005), a "3D as-designed" model (CDRL A007), and a "simplified overhaul manual" (CDRL A006).

Not explicitly stated in this document, but implies a depot-level overhaul process.

• Technical References: Requires adherence to numerous Technical Orders (T.O.s) including 1C-5M-23, 1C-5M-36, 1C-5M-4-1, 33B-1-2, 1C-5M-3, and 1C-5M-6W-8.
• Modifications: Requires adding a quarter inch trim on exterior/perimeter skins/edges, except for the inboard-most edge.
• First Unit Repair Verification (FURV): Requires documentation of repairs, material analysis, process certifications, supplier quality inspection reports, and photo documentation of data plates (overhaul and IUID).
• 3D Model Comparison: Requires creating an "as-manufactured" 3D model and performing a CAD compare analysis against the "as-designed" model, with strict constraints on mounting points and deviation reporting.
• Discrepancy Reporting: All discrepancies must be recorded on a discrepancy log sheet and marked on the part with a red marker. Significant findings outside of T.O. limits or requiring engineering disposition must be reported via AFMC Form 202.

Other / Unclassified

This document is a Request for Information (RFI) to identify potential sources capable of repairing the C-5 Aft Cargo Center Door (Left & Right sides). The government requires one-time repair for each side. The document specifies the National Stock Numbers (NSNs) for the Left Side door (1560012966316) and the Right Side door (1560012979975), along with their respective Repair/Maintenance/Supply Classification (RMC/RMSC) codes (R1/G and R2/G). It notes that while the RMC/RMSC data suggests competitive repair, the government may intend to award to the existing TT&E source to avoid delays. Samples are not available, and the doors are installed on only two aircraft. The contractor will be responsible for furnishing all materials, support equipment, tools, and services. ES3, Inc. is identified as the known sole source for this effort.

This RFI seeks information on potential sources for C-5 Aft Cargo Center Door repairs. It includes a Statement of Objectives (SOO) and a Contractor Capability Survey. Bidders are instructed to provide documentation supporting their capability to meet the requirements. Special attention is given to Small Business Respondents, who are asked to detail their capabilities, potential teaming arrangements, and any work areas they believe could be exclusively set aside for small businesses. The survey covers general business information, general capability questions, repair-specific questions, and commerciality questions. Responses are due by a specified date and should be submitted via email to the PCO and Rebecca Lopez. Participation in this survey does not guarantee future contract awards, and no expenses will be reimbursed.
