What is the first step that a technician should take if an overhauled part is received without required documentation?

When a technician receives an overhauled part without the required documentation, the first step should be to contact the repair station for the appropriate documents. This action is crucial because documentation serves as proof that the part has been overhauled correctly and meets all regulatory and airworthiness standards. Without the necessary paperwork, such as an FAA Form 8130-3 or equivalent, the technician cannot verify the history and compliance of the part, which is vital for safety and legal liability.

Obtaining the proper documentation ensures that the part can be traced back to its maintenance history, and it provides assurance that it has been repaired or overhauled following all applicable regulations. This step aligns with industry best practices and regulatory requirements concerning the use of aircraft parts. Thus, contacting the repair station is critical to maintaining safety and compliance in aviation maintenance practices.
