Security Directives

5.1 Airworthiness Directives and Mandatory Permit Directives are widely published on NAA websites and other propriety information systems. Operators and aircraft owners therefore have ready access to the necessary mandatory safety data for continued airworthiness purposes.

5.2 In addition there are Airworthiness Directives that address deficiencies in aircraft security measures that are not widely published, for example flight deck door modifications.

5.3 These security ADs are circulated to Airworthiness Authorities as the need arises. ASSI and the OTAAs will therefore advise operators and owners directly of the existence of these security AD’s and the need for compliance, as appropriate.
