The signature of an authorized person on the maintenance records for maintenance and alterations performed constitutes

• A. Agreement that maintenance is performed
• B. Authorization to return to service for all airworthiness items
• C. Approval for return to service only for the work performed
• D. Record of maintenance activity completed

Answer: (C)

The key idea is that the signature on maintenance records is a certification that the specific work done is complete and the aircraft is safe to be returned to service for that work. The authorized person is not giving a blanket approval for every airworthiness item on the aircraft, nor merely acknowledging that maintenance happened. Instead, the signature acts as approval to return to service for the particular maintenance or alteration performed, confirming it meets required standards and can be relied upon for that work. If other items still require attention, those would need separate follow-up and authorization. This is why the correct interpretation is that the signature provides approval for return to service only for the work performed.
