End items of support equipment coded as technically nonrepairable shall be included, but shall be supported by an illustration and parts list only. 5.3.6 Local manufacturing and assembly work package locmfgwp >. a. Fabrication procedures for items source coded as "Make From" (MO, MF, MH, MG, MD) or "Assemble From" (AO, AF, AH, AG, AD) at the appropriate maintenance level shall be provided. The data shall include identification of the exact material required. When multiple items have common coverage requirements, the items may be covered in the same WP or series of WPs (e.g., cable assemblies).
Simple procedures, adequately depicted in the IPB, shall not be covered. b. For engines , information required for the fabrication of items source coded "Make From" (MO, MF, MH, MG, MD) and "Assemble From" (AO, AF, AH, AG, AD) shall be included unless the manufacture of the item is obvious. Only those items listed in the applicable IPB shall be considered. The data shall include identification of the exact material required. 5.3.7 Power plant build-up work packages. A series of work packages shall be developed covering the build-up requirements for a basic engine to meet the configuration required for aircraft installation.
Power plant build-up instructions shall cover applicability and interchangeability of QEC units, preparation of engine build-up, and ground handling of engines. When required, the engine test procedures shall be referenced. IPB data shall be included in the work packages described in 5.3.7.1 through 5.3.7.5. The IPB data shall identify the Quick Engine Change Kit (QECK) items in accordance with 5.3.11. 5.3.7.1 General information work package . This work package shall contain general procedures and precautions, lockwiring and cotter pin installation, fitting installations, and standard torque values required to perform engine build-up.
5.3.7.2 Quick Engine Change Kit (QECK) description work package . This work package shall include a listing of the components and equipment which comprise the QECK. A brief description of the components and equipment shall be included. 5.3.7.3 Quick Engine Change Assembly (QECA) work packages . Work packages shall be developed for the removal of the basic engine from the Quick Engine Change Stand (QECS) and the installation of the basic engine in the QECS. Additional work packages shall be developed, in appropriate order of sequence, covering the installation instructions of all QECK components on the basic engine. These instructions shall include all securing and QA check procedures.
5.3.7.4 Non-Quick Engine Change Assembly (non-QECA) work packages . A series of work packages shall be developed, in appropriate order of sequence, for the teardown (removal) and build-up (installation) of all non-QECA components. These procedures are required to make the QECA a complete specific aircraft power plant. Instructions shall include all securing and QA check procedures. 5.3.7.5 Additional power plant build-up work packages . Work packages shall be prepared for additional procedures that may be required to complete the power plant build-up. These additional procedures may include preservation, packaging, depreservation, corrosion control, and structural repair, as applicable.
5.3.8 Preinduction and mandatory inspection work package (engines only) . Preinduction and mandatory inspection requirements covering any engine inducted at intermediate or depot maintenance level shall be prepared as a separate WP. The WP shall detail inspection/investigation 15
