"Given the ambiguity of FAR 145.163, the draft AC constitutes
the FAA’s only guidance for the development of training
programs for repair stations certificated under Part 145. Issuing
the draft AC with only a 30-day comment period does not allow
affected entities the opportunity to evaluate and comment on this
comprehensive document."

Government and Industry Affairs, in comments submitted to the FAA.
NATA is the second alphabet group to request an extension of the
comment period on the proposed FAR.
