According to JAR-145, what must be issued after each kind of maintenance?

The correct response indicates that a Certificate of Release to Service must be issued after each kind of maintenance as stipulated by JAR-145, which is a regulatory framework established for the maintenance of aircraft and aircraft components. This certificate serves as a formal declaration that the maintenance work has been completed satisfactorily and in compliance with the applicable requirements. It confirms that the aircraft or component is safe to return to service and meets all necessary regulations and standards.

Issuing a Certificate of Release to Service is crucial because it ensures accountability and traceability in aircraft maintenance, enhancing safety by verifying that all maintenance tasks have been performed and that the aircraft is in condition for operation before it is returned to service. This process is vital for maintaining the integrity of aviation safety protocols.

The other options—Certificate of Airworthiness, maintenance statement, and maintenance log—serve different purposes within the context of aircraft operation and maintenance. The Certificate of Airworthiness relates to the ongoing airworthiness of the aircraft, not specifically tied to maintenance actions. A maintenance statement may document certain details and outcomes of maintenance but does not carry the same legal and operational weight as a Certificate of Release to Service. A maintenance log is a record-keeping tool that tracks maintenance history but again does not certify the completion of maintenance work
