What is a CDI expected to certify through their inspections?

A CDI is expected to certify that all maintenance has been performed correctly through their inspections. This responsibility is crucial because the primary role of a Collateral Duty Inspector is to ensure that equipment and systems meet the specified standards and are safe for use. The inspection process verifies compliance with established regulations, procedures, and technical data, confirming that tasks have been performed according to guidelines, which directly impacts operational readiness and safety.

By ensuring that maintenance is correctly performed, a CDI plays a vital role in maintaining the integrity and reliability of equipment. This certification process is essential to identify any possible lapses in the maintenance work that could lead to failures or safety issues. In contrast, the other choices focus on aspects that, while potentially relevant to the broader context of operations, do not capture the specific function of a CDI in certifying proper maintenance performance.
