Return the assembly to 73 ±18 °F and perform the test specified in 4.5.2.l.l.
4.5.2.3 Mission reliability test. The mounting kit shall be subjected to 11 one hour
missions. The missions shall be conducted in accordance with 3.14.1. All incidents shall be
scored against the failure definition (see 3.14.2) by the authorized Government representative.
Nonconformance to 3.14 shall constitute failure of the test.

maintenance ratio shall be calculated. Nonconformance to 3.15.1 and 3.15.2 shall constitute
failure of the test.
4.6 Inspection comparison. The Government may select kits at any time during the first
article period and subject them to the examinations specified in 4.4.2 to determine conformance

the contractor's location and witnessed by the Government on kits selected at random from those
which have been accepted by the Government, but will not include the previously inspected first
article kits.
4.6.1 Inspection failure. Failure of an inspection comparison kit to meet any requirement
specified herein during, and as a result of, the examination shall be cause for rejection of the
inspection comparison kit and shall be cause for refusal by the Government to continue
acceptance of first article kits until evidence has been provided by the contractor, at no cost to
the Government, that all deficiencies have been corrected. Any deficiencies found as a result of
inspection comparison will be considered prima-facie evidence that all kits accepted prior to the
completion of inspection comparison are similarly deficient, unless evidence to the contrary is
furnished by the contractor and such evidence is acceptable to the Government.
