3.5.2 Maintainability.
#
3.5.2.1 Maintenance engineering analysis (MEA). When specified (see 6.2.1), the
#
supplier shall conduct before the design tests a MEA. The MEA shall be conducted for each
functional system, equipment, unit, assembly, or subassembly which requires maintenance
and the continued operation of which is essential to the successful completion of a mission
itself. The supplier shall prepare an MEA report in accordance with the data ordering docu-
ment included in the contract or order.
3.5.2.2 The design shall provide accessibility to all parts which require examination,
#
preventative maintenance, or replacement in service with the minimum practicable need for
disconnection or removal of another part or assembly. Access panels, covers, peep holes,
etc. shall be employed to the fullest extent feasible and compatible with the intended
examination or maintenance action. The envelope of the minimum required space around the
unit which is needed for ease of maintenance shall be shown on the installation drawing
(see 3.12.1).
3.5.2.3 All parts, including repair parts furnished under the same contract or order
#
or manufactured to the same drawings shall be interchangeable without the necessity for
further machining, selective assembly, or hand fitting of any kind to the fullest extent
feasible.
#
3.5.2.4 Maintainability requirements shall be demonstrated during the post first
article test and examination (see 4.4.4) . The supplier shall prepare a maintainability
demonstration report in accordance with the data ordering document included in the contract
or order.
3.6 System safety program. The supplier shall prepare a system safety program plan
#
and system hazards analysis report in accordance with the data ordering document included
in the contract or order (see 6.2.2) .
