MIL-STD-1289D
5.3.4 Accessibility tests.
Accessibility requirements will be verified by performance of all operations required for checking, filling or loading, and removing safety pins, and adjusting the stores. The operations will be performed with the aircraft in its normal ground attitude and in the sequence determined by the loading procedure test (see 5.3.2). The appropriate hand tools will be used to make adjustment on the store fittings, fuze installations, arming wire attachments, and any other equipment maintenance. Hand and tool space shall be evaluated for ability to perform operations, adjustments, etc., considering protective clothing worn by operational loading personnel.
5.3.5 Store reinforced area test.
The store shall be checked for proper alignment between the ejection mechanism and the store- reinforced area. Applicable preloads shall be introduced to the store through the sway braces. The store structure shall be inspected to verify support of the installation loads without permanent set in any portion of the store structure exceeding that outlined in MIL-A-8591.
5.3.6 Electrical function test.
Functional tests or calibrations to demonstrate proper operations of the equipment being tested shall be performed.
5.3.6.1 Electrical interface.
All electrical connections between the store and the pylon/aircraft structure shall be checked for possible sources of mechanical and electrical failure caused by improper cable routing. Particular attention shall be given to wiring that could be susceptible to strains or short circuits resulting from movement by airstream forces and all connections reviewed with an understanding of the electromagnetic interference, bonding and hazardous radiation requirements of MIL-STD-464.
5.3.6.2 Store functional check.
Functional checks shall be conducted to ensure proper continuity of all electrical circuits and proper operation of all electrical/electronic equipment. The actual or simulated operation evaluations may be made using special test equipment. This includes validation and verification of store software.
5.3.6.3 Armament control system check.
Functional checks on each installation of the control and monitor circuits shall be made. Where possible, it shall include functioning of power sources, functioning of all circuits up to release of firing mechanisms, functioning of all safety devices, and checking of all armament indicator lights. This includes a check of the software used in the operational flight program to control the store. Armament systems which are capable of adjustable firing angles (elevation, depression, azimuth, for example, gun turret systems) shall be checked to verify positive stops and clearances to prevent damage to the aircraft structure or rotor/propeller disk. Sufficient tests shall also be conducted to ensure that inadvertent release does not occur as a result of cockpit switch selection procedures or hardware/software deficiencies.
