4.5.2.2.2 All markings required by final assembly drawings shall be
visually examined for clarity and legibility.
4.5.3 Testing.
*
4.5.3.1 Failure data. Unless otherwise specified herein, all tests
shall be conducted on a complete launcher. Failure of the launcher to
meet the test requirements specified herein shall be cause for rejection
of the launcher or the inspection lot of launchers. Acceptance of
launchers shall be deferred and the contractor shall accomplish as applicable
the following actions:
a. Conduct a failure analysis study performing a dimensional
physical and visual examination of the components which are
suspected to be the cause of failure or malfunction.
b. Evaluate and correct the applicable production processes
and procedures to prevent recurrence of the same defect(s)
in future production.
Examine launchers, partially assembled launchers, and com-
ponents (including components and subassemblies at inprocess
of final assembly) to insure that material containing the
same defect is purged from the inventory and not presented
to the Government for acceptance.
d. Submit the results of the failure analysis and the
corrective actions taken to the Government for review
and approval prior to submitting a reconditioned lot or
reconditioned launcher for retest.

4.5.3.2 Pump actuation, barrel stop, barrel latch, cartridge locator
and cartridge ejector testing. A sample of 50 launchers shall be randomly
selected from each inspection lot and tested for pump actuation (see 3.2.2.1),
barrel stop (see 3.2.2.2), barrel latch (see 3.2.2.3), cartridge locator
(see 3.2.2.5) and cartridge ejector (see 3.2.3.2) using test methods 4.7.1.1,
4.7.1.2, 4.7.1.3, 4.7.1.4 and 4.7.2.1 respectively. Failure of the launcher
to pass any of the tests shall be cause for rejection of the represented
lot. Reconditioned launchers or reconditioned lot shall be tested using
the procedures and test methods specified above.
*
4.5.3.3 Firing pin indent and firing pin protrusion testing. A
sample of 10 launchers shall be randomly selected from each inspection
lot and tested for firing pin indent (see 3.2.3.7) and firing pin pro-
trusion (see 3.2.3.8) using the methods specified in 4.7.2.2 and 4.7.2.3.
Failure of the launcher to pass any of the tests shall be cause for re-
jection of the represented lot. A sample of 20 launchers from each re-
test or reconditioned lot shall be tested using the procedure specified
above.
