When should a QAR/CDQAR perform an In-process or Final inspection?

The most appropriate time for a Quality Assurance Representative/Collateral Duty Quality Assurance Representative (QAR/CDQAR) to perform an In-process or Final inspection is when maintenance requires a Functional Check Flight (FCF). These inspections are critical to ensure that all associated maintenance functions are completed correctly and that systems are operable before any flight operation, such as an FCF, occurs.

An FCF is designed to validate the integrity and performance of an aircraft after maintenance has been performed. The QAR/CDQAR must confirm that everything meets the established standards and specifications before this flight takes place, ensuring that safety and operational readiness are prioritized.

In contrast, the other options do not align with standard inspection criteria. Approaching deadlines may create urgency but do not inherently trigger inspections, nor do requests from the CDI; requests can occur for various reasons, but inspections should follow maintenance requirements primarily. Lastly, simply receiving and screening materials doesn't encompass the broader context of maintenance activities that necessitate a systematic inspection during or after the completion of those tasks.
