1, 2, 3 and 4 of this AD, for the maintenance of the cockpit voice recorder.
                This AD commences on 23 March 2016.
Background:     The maintenance procedures presently applied to some cockpit voice recording systems have been shown to be inadequate. Experience both in Australia and overseas has shown that the above maintenance periods will normally ensure the proper functioning of these systems.
                Amendment 1 was administrative only and removed reference to the obsolete terms of Air Navigation Order (ANO) and Air Navigation Regulation (ANR). Reference to subregulation 43 (3) of the ANR was replaced by subregulations 39 (1) and 41 (1) of CAR 1988.
                Amendment 2 was issued to incorporate the particular audio tracks required to be recorded and listed in CAO 103.20 in anticipation of the cancellation of that CAO. The amendment also acknowledged the increased reliability of modern digital solid state recorders and so extended the compliance time interval for testing. In addition, if modern aircraft have an approved system of maintenance, maintenance schedule or maintenance program that address the requirements of this AD, the intervals within those approved programs may be used for the purpose of compliance with this AD.
                Amendment 3 was issued to limit the applicability of the AD to Part 42 aircraft only.
                Amendment 4 is issued to remove obsolete regulatory references in the compliance section to regulations 41 and 42M of CAR 1988.  The reference to the approved maintenance program under regulation 42.140 has also been clarified to require incorporation of the AD's 4 requirements. This AD will be repealed after the requirements are incorporated into a future amendment of the Part 42 Manual of Standards.
