Which statement best describes the purpose of the internal post-maintenance inspection regarding parts and workmanship?

• A. It verifies that parts are serviceable and workmanship meets approved data.
• B. It assesses cosmetic appearance of replaced parts.
• C. It checks maintenance crew adherence to the schedule.
• D. It verifies maintenance cost.

Answer: (C)

Internal post-maintenance inspection is about quality and compliance: it verifies that the parts installed are serviceable and that the workmanship conforms to the approved data. This check is what ensures the work meets airworthiness standards, since it looks at whether the correct parts were used and installed properly according to manuals, charts, and specifications. It’s not focused on cosmetic appearance, which isn’t a designator of airworthiness, nor on how the crew was scheduled or on the maintenance cost, which are management or financial concerns rather than a measure of proper procedure and part condition. So, the purpose is to ensure parts are serviceable and the workmanship meets the approved data.
