Final answer:
When an aircraft is deemed un-airworthy during a 100 Hour or Annual Inspection, the A&P technician must document the discrepancy in the maintenance records and provide a detailed report upon completion of repairs, including the work performed, date, and technician's identification.
Step-by-step explanation:
If an aircraft is found to be un-airworthy due to discrepancy findings detected during a 100 Hour or Annual Inspection, the A&P technician must complete two written actions:
- The discrepancy must be recorded in the aircraft’s maintenance records. This includes a detailed description of the finding, the condition of the part or system, and any other relevant information that helps to identify and explain the issue.
- Upon completion of the repairs, the technician must provide an entry for each repaired or replaced item. This should include a description of the work performed, the date of completion, and the name and certificate number of the technician who performed the work.
These records ensure that there is a clear history of the aircraft's maintenance, and they provide accountability for the work performed. They're imperative for both compliance with aviation regulations and the assurance of aircraft safety.
