Airworthiness Directives

Airworthiness Directives (ADs) require to carry out mandatory inspections, replacements, changes, limitations or operational procedures, within specified terms of compliance, in order to maintain the airworthiness of the aircraft.

In accordance with Regulation (EC) No 1702/2003, of 24 September 2003, in the Annex Part 21, an airworthiness directive is defined (par.21A.3B) “a document issued or adopted by EASA (European Aviation Safety Agency) which mandates actions to be performed on an aircraft to restore an acceptable level of safety, when evidence shows that the safety level of this aircraft may be otherwise compromised”. For such purpose each AD identifies the unsafe conditions, types of affected aircraft, systems or equipment, which actions are rendered mandatory, compliance time, the effective date. When an AD is not introduced on an aircraft, part or equipment within the specified terms of compliance the Certificate of Airworthiness is no longer valid.

According to Regulation (EC) No 1592/2002, of 15 July 2002, EASA has only taken over Member States obligations that are design approval related. Aircraft which characteristics are defined both in the Annex II to the Basic Regulation, the list may be found at the following address http://www.easa.europa.eu/home/c_da_main.html, and those defined “non transferred aircraft”, remain under responsibility of the Member States.

ADs issued by the Agency may be found at the following address http://ad.easa.europa.eu/. For the time being in the EASA web site are published only ADs approved or issued by the Agency starting from year 2003.

EASA has only competence to issue ADs related to type design. As consequence in those situations where an unsafe condition has been introduced during maintenance or manufacturing, if it affects aircraft registered in Italy Enac will issue the relevant AD.

The database, here available, contains all ADs issued or disseminated by Enac after 1st January 1995. EASA and foreign ADs are published when applicable to Italian registered aircraft, at the time of issue. Enac has a running plan to publish on the web all ADs applicable to products, parts and equipment for which Italy is the State of Design and for aircraft included in the Annex II, if they are registered in Italy, issued before 1st January 1995.

Starting from Enac AD n. 2007-393, the airworthiness directives will be available in a pdf format.

Please address your request concerning Enac ADs to the following email address ad@enac.gov.it.
