PART 39_AIRWORTHINESS DIRECTIVES--Table of Contents
 
Sec.  39.27  What do I do if the airworthiness directive conflicts with 
the service document on which it is based?

    In some cases an airworthiness directive incorporates by reference a 
manufacturer's service document. In these cases, the service document 
becomes part of the airworthiness directive. In some cases the 
directions in the service document may be modified by the airworthiness 
directive. If there is a conflict between the service document and the 
airworthiness directive, you must follow the requirements of the 
airworthiness directive.
