36、.2.1 Maintenance. The equipment specified herein will be operated, main- tained, and repaired on board Navy ships (see 6.3). Human engineering aspects, in accordance with MIL-STD-1472, shall also be fully explored and considered in the equipment design to minimize the possibility of failure through
37、improper operation and maintenance, and to preclude personnel safety hazards. Positioning and alignment of parts shall employ positive means such as shoulder, tongue and groove, or other locating techniques whereby correct reassembly is repeatedly assured. In consonance with the concept of ease of m
