Compliance: As specified in the Requirement document, with a revised effective date of 5 June 2008. This Airworthiness Directive becomes effective on 5 June 2008. Background: The manufacturer has determined that in certain instances the pressure equalisation valve was not installed on the left hand bulkhead blowout panel in the forward and/or aft cargo compartments during production. This condition, unless corrected, could affect the effectiveness of fire detection, containment, and suppression. David Punshon Delegate of the Civil Aviation Safety Authority 7 April 2008
