4.3.2.1.1 Reliability verification. To determine conformance to 3.1.1, the Minimum
Acceptable Value (MAV) of 545 MMBF shall be demonstrated during initial production testing
(see 4.3.2.1). The reliability requirement shall be verified at a point estimate. The point estimate
is computed by dividing the total cumulative test miles (of designated test vehicles) by the total
number of associated mission failures.
4.3.2.1.2 Maintainability verification. To determine conformance to 3.1.2, the
maintainability requirements will be verified during initial production vehicle test (see 4.3.2.1).
4.3.2.1.3 Durability verification. To determine conformance to 3.1.3, the durability
requirements shall be verified during initial production testing, (see 4.3.2.1), at 50% confidence
(Binominal Distribution).
4.3.2.2 Test failure. Failure of the vehicle to comply with any of the requirements specified
or any deficiency of a workmanship or materials nature found on the vehicle during or as a result
of the 20,000 mile or 11,400 mile test, will be cause for rejection of the vehicle. Further, the
Government will refuse to continue acceptance of production vehicles until evidence has been
provided by the manufacturer that corrective action has been taken to eliminate the deficiency
found during or as a result of the 20,000 mile or 11,400 mile test shall be prima facie evidence
that all vehicles already accepted prior to completion of the 20,000 or 11,400 mile tests are
similarly deficient, unless evidence satisfactory to the contracting officer is furnished by the
contractor that they are not similarly deficient. Such deficiencies on all vehicles shal1 be
corrected by the contractor without cost to the Government.
