In a 14 CFR Part 135 operation, who is responsible for ensuring the inspection of maintenance?

In a 14 CFR Part 135 operation, the requirement that the person performing maintenance is not allowed to inspect it is grounded in the principles of safety and quality control within aircraft maintenance. This regulatory framework is designed to ensure an unbiased inspection process.

When maintenance is performed on an aircraft, it is critical that the person conducting the inspection be independent of the work completed. This separation helps to mitigate any conflict of interest that could arise if the same individual both performs and inspects their work. As a result, an inspector who did not participate in the maintenance task is tasked with ensuring that the work meets all applicable standards and regulations as outlined in the Federal Aviation Regulations.

For Part 135 operations, compliance with these regulations plays a critical role in maintaining safety standards and operational integrity. Thus, this option emphasizes the need for independent verification of maintenance actions, reinforcing the importance of having a distinct separation of roles within aviation maintenance practices.
