Common use of POWERPLANT MAINTENANCE Clause in Contracts

POWERPLANT MAINTENANCE. Powerplant Maintenance covers responsibility for maximizing engine maintainability, establishing maintenance concepts and requirements and providing maintenance support plans for IAE. This group provided the following services: • Definition of Maintenance Tasks and Resource Requirements • Planning Guides Powerplant Maintenance conducts design reviews and comprehensive maintenance analysis of new engine designs and engine design changes to maximize engine maintainability consistent with performance, reliability, durability and life cycle cost considerations. Maintenance concepts, requirements and tasks are established to minimize maintenance costs. This group represents Spirit’s maintainability interests in internal IAE operations and upon request will assist Spirit in resolving specific maintenance task problems. *****Confidential portions of the material have been omitted and filed separately with the Securities and Exchange Commission. 4.2.1 Progressive Maintenance Planning: Powerplant Maintenance also provides Planning Guides based upon Maintenance Task Analysis. The guides present engine maintenance requirements, their subordinate tasks and the required resources to accomplish on-aircraft engine maintenance and the off-aircraft repair of engines by modular section/build group replacement. Maintenance requirements are also presented for the refurbishment of modular section/build group by parts replacement, the complete repair of parts, the refurbishment of accessory components and for engine testing. The data in the Planning Guides is presented in a manner that is primarily intended to assist new operators by providing a phased introduction of new engines into their shops and to capitalize on the design maintainability features for the engine when they are developing their maintenance plans. Powerplant Maintenance Engineering will assist new operators in planning a gradual, technically feasible, and economically acceptable expansion from line maintenance of installed engines through the complete repair of parts and accessory components.
