When must the written notice of defect be provided to the owner during an annual inspection?

The requirement to provide the written notice of defect at the conclusion of the inspection ensures that the owner receives complete and immediate feedback on the condition of the aircraft after all evaluations have been performed. This timing allows for a comprehensive report that includes all findings from the inspection without any delay or incomplete information being relayed. Information shared at the end helps the owner understand any necessary actions, repairs, or further investigations that might be required based on the inspection results.

In this context, providing the notice at the conclusion also allows for clear communication between the inspector and the owner regarding any issues identified. If the notice were given immediately after the inspection or before the cabin is closed, it could potentially lead to misunderstandings, as the full scope of the inspection may not have been completed at that point. Similarly, while providing a notice within a certain timeframe might seem sufficient, it might not guarantee that the owner receives the information right when it is most relevant. Therefore, delivering the notice at the conclusion combines thoroughness with prompt communication, aligning with best practices for aircraft inspections.
