Section 39.27

14 CFR Ch. I (1-1-19 Edition)

Section 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.
