ADs - Engines

Completed pages (PDF files) for the Airworthiness Directives Logbook will be shown next to the appropriate Airworthiness Directive as they are completed. More completed pages will be added as time permits. If you have created some completed pages and would like to help us with this project, please email them to:

Important Notes: These completed Airworthiness Directive pages are provided as a helpful aid. They may not be updated at the same time as the Airworthiness Directive Schedules. We have provided a text box on the top right side of the Airworthiness Directive logbook page (next to the page number) that will show the date of the latest Airworthiness Directive Schedule that the logbook page was updated to.

So remember the Airworthiness Directive Schedule is always the definitive list of the current Airworthiness Directives.
