Downloaded from https://www.everyspec.com ADS-39A (HDBK) Source Approval and Engineering Test Requirements for Alternate Sources of Helicopter Drive System Assemblies and Components 1 Scope 1.1 This Aeronautical Design Standard (ADS) specifies Source Approval and Engineering Test requirements for alternate sources of helicopter drive system assemblies and components. These requirements are necessary to insure that an alternate source has the advanced manufacturing and assembly skills required to produce these complex parts.
Completion of these requirements before contract award is necessary to reduce procurement risk associated with overcoming technical issues with first-time producers of these parts. Fielding of parts before the capabilities of the alternate source is substantiated could result in failures and/or early removals in the field, which may significantly impact the safety and reliability of the weapon systems they are used on. These requirements are based on the requirements used to qualify the original source of the part. The requirements specified in this ADS must be substantiated by a candidate alternate source before they will be approved to bid on a contract for that part.
1.2 This ADS does not specify fatigue test requirements. 1.3 This handbook is for guidance only. This handbook cannot be cited as a requirement. If it is, the contractor does not have to comply. 2 References Competition Advocates Shopping List (CASL) Engineering Test Standard One (TEST-STD-1) Engineering Test Requirements for New Sources Quality Engineering Standard One (QE-STD-1) Flight Safety Parts - Quality System Requirements 3 Requirements 3.1 General 3.1.1 Components for which this ADS applies are listed in Attachment 1. 3.1.2 Approval of a candidate alternate source to provide a specific component does not imply the alternate source is approved to provide other components. 1
Downloaded from https://www.everyspec.com ADS-39A (HDBK) 3.1.3 When a component listed in Attachment 1 is an assembly (i.e., it contains other components) the alternate source must become approved to produce those parts used in that assembly which are not being procured from approved sources. The alternate source must meet the requirements specified in this ADS for all of the components they produce themselves and for which they have not previously been given approval. They must also meet the requirements specified in this ADS for the assembly itself. Components which are assemblies of other parts are listed in Attachment 1.
3.2.2.1 When the design of a component listed in Attachment 1 is controlled by a Source or Specification Control Drawing (SCD), the candidate alternate source shall provide their detail design drawings for review and approval. Complete and specific qualification requirements and a detailed statement of work shall be provided to the candidate alternate source after their design drawing is approved. For SCD parts, qualification of the design as well as of the manufacturing and/or assembly process is required. Components controlled by Source or Specification Control Drawings are identified in Attachment 1.
3.2 Source Approval 3.2.1 General 3.2.1.1 Most of the substantiating documentation required by this ADS is submitted as part of a sources Source Approval Request (SAR) per the Competition Advocates Shopping List (CASL) Instructions. All documentation and data required by this ADS which is not submitted as part of the SAR shall be submitted to ATCOM Engineering, AMSAT-R-EB. 3.2.2 Specifications 3.2.2.1 The candidate alternate source shall certify they have legal access to all required specifications (e.g., assembly, manufacturing, processing, inspection, etc.) required by the applicable drawing and Spares Technical Data Package (STDP).
3.2.3 Material 3.2.3.1 For all components, the candidate alternate source shall certify that the material used meets all applicable drawing and material specification requirements. For components produced from castings or forgings, the candidate alternate source shall certify that the casting or forging supplier is an Government-approved source. Components made from castings or forgings are identified in Attachment 1. 3.2.4 Flight Safety Parts 2
Downloaded from https://www.everyspec.com ADS-39A (HDBK) 3.2.4.1 Processes affecting Critical Characteristics of Flight Safety Parts must be performed by Government-approved sources. The candidate alternate source shall identify all sources who will be performing processes which affect Critical Characteristics. Flight Safety Parts are identified in Attachment 1. 3.2.5 Manufacturing Plan 3.2.5.1 When required, the candidate alternate source shall provide a copy of the manufacturing plan to be used for the component. When applicable, the manufacturing plans for any subcontractors used in the production of the part shall also be provided.
3.2.5.2 The manufacturing plans shall completely define the manufacturing and inspection process, including sequence of operations, equipment used for each task, specifications and standards used, inspection requirements, personnel requirements, etc. For assemblies of parts, the assembly procedure shall be defined. Details of process sensitive operations such as furnace loading, heat treatment times, temperatures, quench methods, maximum time delay prior to bake after plating, shot peening setup, etc., shall be provided when applicable. When applicable, balancing procedures shall be provided. Components which require balancing are listed in Attachment 1.
3.2.5.3 The manufacturing plan shall include all quality assurance procedures that will be implemented on production components. This plan shall include type of inspection performed, number of components in each lot inspected, lot sizes, Critical Characteristic inspection compliance procedures, etc. Plans for use of components/coupons for heat treat/carburization quality assurance purposes shall be provided. 3.2.5.4 The candidate alternate source shall provide a complete listing of all equipment to be used in the manufacture and inspection of the component. Calibration requirements for all equipment shall be provided.
3.2.5.5 The manufacturing plan shall include a complete listing of all subcontractors used during the manufacturing process. The list shall include subcontractor name, CAGE (Contractor and Government Entity) Code, address, telephone number, and description of the work to be done by the subvendor. Certification by the sub-vendor that they have agreed to perform the work indicated shall be provided. This information must be provided for the subcontractor who will actually perform the work, not for a list of subcontractors who are capable of doing the work. 3.2.5.6 The candidate alternate source shall provide a copy of any non-Government documents referenced in the manufacturing plan.
Proprietary data will be fully protected by the Government. 3.2.5.7 Components for which manufacturing plans are required are listed in Attachment 1. 3.2.6 Bevel Gears 3
