b. Units are loaded with same lots of rocket motor grain assemblies, catapult grain assemblies,
external igniter assemblies, and rocket motor igniters (see 3.2.3.3, 3.2.3.5, 3.2.3.7, and
3.2.3.8).
4.4.2.2 Sampling for examination. Designation of defects (critical, major, or minor) shall be in
accordance with DOD-STD-2101.
a. Critical and major defects: Each rocket catapult assembly (Drawing 513-174-0100 or
Drawing 513-174-0200) shall be examined for all critical and major defects (see 4.4.4.1).
b. Minor defects: Sample rocket motor catapult assemblies (Drawing 513-174-0100 or Drawing
513-174-0200) submitted for examination shall be selected in accordance with general
inspection level II of ANSI/ASQC Z1.4, AQL 2.5 (see 4.4.4.2).
c. Components: Unless a specific contractor-generated inspection plan for all subcontracted
components has been approved by the procuring activity (see 4.4.4.3), the following sampling
for components shall apply. All rocket catapult components shall be examined for all critical
defects. Sampling for other defects shall be in accordance with level II of ANSI/ASQC Z1.4,
AQL 1.0 for major defects and AQL 2.5 for minor defects.
4.4.2.3 Sampling for firing test. A sample of loaded rocket catapult assemblies shall be submitted to the
Indian Head Division, Naval Surface Warfare Center, Indian Head, MD 20640-5000, for static firing in
accordance with 4.4.5. The sample size shall be in accordance with table IV. Samples shall be chosen by
Indian Head Division, Naval Surface Warfare Center, Indian Head, MD personnel or by a designated
Government representative upon completion of the production lot assembly. Loaded rocket catapult
samples shall not be preselected during production. Rocket catapults selected for samples shall not be
included as part of the quantity specified for delivery in the contract or order. The ballistic sample size
shall be divided as equally as possible among rocket motor batches and catapult batches. From each
rocket motor batch or catapult batch not represented in the sample rocket catapult assemblies, one sample
rocket motor or catapult grain shall be selected for static firing by the contractor (see 4.4.5.1), so that at
least one rocket motor or catapult grain from each batch has been static fired.
4.4.2.4 Sampling for nondestructive test. Each rocket catapult assembly shall be subjected to the tests
specified in 4.4.6.
