SCOPE:

This Statement of Work (SOW) defines the requirement to provide fourteen (14) Enhanced Service Life (ESL) Center Wing Box (CWB) Structural Assemblies, thirteen (13) Component Modification kits top level part number 3367300-3, and one (1) Component Modification kit top level part number 3367300-1. The structural assembly and corresponding component kit shall henceforth be referenced as the ESL Center Wing Replacement (CWR) Modification Kit.

BACKGROUND:

The CWBs on select C-130J aircraft are reaching the end of their designed service life and must be replaced. Lockheed Martin Aeronautics Company (LMAC), the C-130J original equipment manufacturer (OEM), incorporated the ESL CWB into aircraft production effective on Lockheed Martin Serial Number (LMSN) 5619 and up. Contract FA8504-14-C-0003 commissioned LMAC to design retrofit kits to install this same ESL CWB onto C-130J aircraft originally delivered with a standard CWB (5618 and prior). The United States Air Force (USAF) has been procuring these ESL CWR Modification Kits since 2014, and has been installing them on C-130Js since 2016.

1.0 C-130J ESL CWR MODIFICATION KITS

1.1 C-130J ESL Structural Assembly -- The baseline configuration for the ESL CWB shall be 3367300-11.

1.2 C-130J Components Modification Kit -- The C-130J Components Modification Kit shall include all system components including plumbing, wiring, and all other material necessary for center wing replacement for the affected aircraft. The baseline kit configuration shall be 3367300-1 and 3367300-3.

1.2.1 ESL CWR Modification Kit Manufacture, Assembly, and Delivery -- The contractor shall deliver a complete ESL CWR Modification Kit manufactured in accordance with top level drawing 3367300. The CWR kit/kits of each order shall be delivered according to the schedule negotiated at time of contract award. The contractor is responsible for ensuring there are no discrepancies between assembly/fabrication drawings supplied and the actual delivered assemblies with the exception of Material Review Board (MRB) action performed in accordance with the LMAC MRB process. The contractor shall manufacture CWR kits subject to the ISO 9000 family of standards, guidelines, and technical reports.

(A011: DI-ADMN-81249B/T)

1.2.2 ESL CWR Modification Kit Description -- The ESL CWR Modification Kit, as identified in the subsequent paragraphs, consists of the ESL CWB structural assembly and the component modification kit. The center wing components modification kit shall be packaged separately from the ESL CWB structural assembly.

1.2.3 ESL CWR Modification Kit Composition -- The ESL CWR Modification Kit will consist of ESL CWB structural assembly part number 3367300-11, and a center wing components kit part number 3367300-1, or part number 3367300-3, based on Contract Line Item Number (CLIN). The center wing components modification kit will be specific for the affected aircraft variant and include all systems, modification components, and installation components necessary to install the ESL CWR Modification Kit in that model aircraft as delivered from LMAC. The contractor shall also consider Block 7.0 and Block 8.1 changes to identify risks or potential design compatibility issues.

1.3 Packaging -- Packaging shall be in accordance with Air Force Material Command (AFMC) Form 158 and the paragraphs below:

See PART II – CONTRACT CLAUSES, for the DFARS clause reference and information on additional items that may require unique identification. The provisions of the DFARS clause are mandatory and take precedence over any exclusion in MIL-STD-130. For purposes of this SOW, the only two (2) items to be IUID marked in CWR Modification Kits are the structural assembly and the component kit.

2.5 Over and Above (O&A) -- Any tasks not included in this SOW shall be negotiated as O&A. When contacted by the Administrative Contracting Officer (ACO), the contractor shall list all services, indirect material (excluding those exceptions authorized by the ACO), and all engineering necessary to accomplish the task. The contractor shall be responsible for submitting a written work request to the ACO for authority to perform negotiated O&A work as soon as the need for such work becomes known. The work request proposal shall include a quote for the man-hours, contractor furnished material (material costs will be determined as part of the negotiations/award) needed for that task, and a detailed description of overall schedule impact. Labor rates will be set forth in the contract for these O&A tasks. The ACO must approve these requests before work can be performed.

2.6 Quality -- The contractor shall comply with the International Standards Organization (ISO) 9000 (or higher) family of standards, guidelines, and technical reports. The contractor shall permit the Government to periodically access quality related data and data related records for the C-130J CWB on a non-interference basis. The contractor is ultimately responsible for the quality and suitability of products and materials provided by its subcontractors. The Government has the right to request corrective action if the quality system proves incompatible with material, process, or schedule requirements of the Government’s CWB production environment.

The TDP shall provide the necessary design, engineering, manufacturing, testing and quality assurance requirements information necessary to enable the procurement or manufacture of an interchangeable item that duplicates the physical and performance characteristics of the original product without additional design engineering effort or recourse to the original design activity or any third party. The TDP shall represent the approved, tested, and accepted configuration of the defined delivered item(s). This shall include software and all test requirement documentation data required to test systems, subsystems and/or components. Vendor Item Control Drawings shall be used to specify the requirements for purchased items when such items have been approved for use in the design and are used without alteration, selection or source qualification (testing of an item prior to procurement action to ensure that it satisfies the specified requirements). All engineering product definition data created using Government funding as a result of this contract shall be considered a part of the TDP and shall be delivered to the Government with unlimited rights. The TDP shall be created IAW the following American Society of Mechanical Engineers (ASME) standards: ASME Y14.100-2017, Appendix B, sections B6 through B9.1 and Appendices C, D, E, and F in conjunction with ASME Y14.24-2012, ASME Y14.34, ASME Y14.35 and ASME Y14.41 and as defined in the corresponding CDRL for this task to create and deliver Product Drawings Models and Associated Lists (Engineering Data) under this contract.
