Logbook entries when done properly, describe work accomplished on the aircraft, convey critical information about the aircraft’s airworthiness, offer protection for the individual or company accomplishing the work, and allow for the legal (FAA Sanctioned) Return to Service of the aircraft if found to be Airworthy.

Title 14 CFR Parts 43.9 and 43.11 both have a specific purpose in accomplishing this work. Both sections require their own unique language for signing-off the work in accordance with the applicable event. And both specify who is authorized to undertake the work, what constitutes a proper sign-off, and the type and content of the maintenance entry to be entered into the aircraft’s permanent maintenance record.

Consequently, it is essential to know how to create a correct and accurate Title 14 CFR Part 43.9 or 43.11 Entry and Return to Service document as well. Your living and the life it affords you may depend on it.


The objective of this course is to better understand Title 14 CFR Parts 43.9 and 43.11, and to distinguish the difference between them.

The course goes into an in-depth study on what is to be included in a complete and accurate 14 CFR 43.9 or 14 CFR 43.11 maintenance entry, who is authorized to accomplish work delineated, and the information that must be included in the entry, along with a proper Return to Service approval.


This course will benefit A&P Technicians and Students, IA’s, Repair Station Technicians and Inspectors, Repairmen, and anyone needing a better understanding of aircraft logbook entries and Return to Service approvals, or are contemplating creating an aircraft logbook entry in the future.
