4.2.2 Initial production inspection. Unless otherwise specified (see 6.2), the Government

shall select two units, from the first ten engines produced under the production contract for initial

production inspection. Initial production inspection shall include the examinations of 4.4

(see table IV) and the applicable tests of 4.6.1 through 4.6.16 (see table V).

4.3 Conformance inspection. Conformance inspection shall include the examinations of

4.4 and the applicable tests marked with an X in table V.

4.4 Examination.

4.4.1 Sampling. Samples from an inspection lot for conformance inspection shall be

selected in accordance with ANSI/ASQC Z1.4. Any redesign or modification of the contractor s

standard to comply with specified requirements shall receive particular attention for adequacy

and suitability. This element of inspection shall encompass all visual examinations, dimensional

measurements, and functional requirements listed in table IV. Noncompliance with any

specified requirement or presence of one or more defects preventing or lessening maximum

efficiency shall constitute cause for rejection.

4.5 Conformance tests.

4.5.1 Acceptance tests (100 %). Each engine submitted shall be subjected to the tests

specified in table V.

4.5.2 Control tests (50 hour). A 50 hour control test shall be conducted on one engine

selected at random from each lot of 100 engines produced. However, not more than two engines

shall be tested in any 30 day period. If production is less than 100 engines per month or on

curtailed production, one engine in every 60 day period shall be tested. The engines shall be

subjected to the tests as specified in table VI after being examined for deficiencies specified in

table IV and shall conform to performance requirements listed in table V. The engine shall be

operated for 50 hours as near continuously as possible.

4.5.2.1 Power check test. The engine shall be operated according to the schedule as

listed for period 7 in table VI. The performance characteristics for the power check test shall be

as listed under control test in table V.
