Airworthiness Directives & Service Bulletins FAA – EASA – 1 Day


An Airworthiness Directive (A.D.) is a directive issued by FAA or EASA (or any regulatory authority) that determines that a safety condition exists in a product, part, or appliance –(aircraft engine, airframe, appliance, or propeller). They notify aircraft operators and owners of potentially unsafe conditions that need special inspections, alterations, or repairs.

A Service Bulletin is the document used by manufacturers of aircraft, their engines, or their components to communicate details of modifications that can be embodied in aircraft. If an available modification is judged by the manufacturer to be a matter of safety rather than simply product improvement, then these would be issued as an Alert SB in which case a corresponding Airworthiness Directive (AD) would usually then be issued by the appropriate NAA.

It is important to note, that an operator may need to follow Airworthiness Directives (ADs) from different sources. First and foremost, there are ADs issued by the Civil Aviation Authority (CAA) of the operator.

Each operator must also follow all ADs issued by the CAA appropriate for the type certificate holder of the given aircraft or engine, or the country of manufacture for other components.
