FOREWARD

Airworthiness Directives (ADs) are substantive regulations issued by the Federal Aviation Administration in accordance with part 39 of the Federal Aviation Regulations (14 CFR part 39). Airworthiness Directives are issued when (1) an unsafe condition has been found to exist in particular aircraft, engine, propellers, or appliances installed on aircraft, and (2) that condition is likely to exist or develop in other aircraft, engines, propellers, or appliances of the same type design. Once an AD is issued, no person may operate a product to which the AD applies except in accordance with the requirements of that AD.

The purpose of this Airworthiness Directives Manual is to provide procedures for the development, issuance, and distribution of Airworthiness Directives (ADs). This manual is to be used as a companion to Order 8040.1C, Airworthiness Directives. The order provides policy, delegation, and responsibility; the Manual provides detailed processing procedures. This Manual will be updated and changes will be issued as necessary.
