Final answer:
Inspect individual qualification/certification records and EDVR to ensure aircraft engine test cell operators possess NEC 6422/MOS 6023 or an artisan equivalent series designation.
Step-by-step explanation:
Inspecting individual qualification/certification records and the Enlisted Distribution Verification Report (EDVR) can help ensure that all aircraft engine test cell operators who have qualified for a certain period possess the NEC 6422/MOS 6023 or an artisan equivalent series designation. By reviewing these records, the company can verify that the operators have the necessary qualifications and certifications to perform their role in the test cell. The length of time required for qualification can vary and may depend on company policies or industry standards.
