 COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
 SCHEDULE OF AIRWORTHINESS DIRECTIVES

            Background: The Netherlands Rijksluchtvaartdienst (RLD) has received reports of inflight deployment of liftdumpers, this resulted in the issue of three separate Dutch airworthiness directives. CASA responded by issuing AD/F100/33 and AD/F100/38. Since then the RLD has received another report of inflight liftdumper deployment.

            This Directive introduces an AFM amendment to ensure flight crew do not arm the liftdumpers before the landing gear is down and locked. The RLD anticipates that following further investigation, additional rulemaking action may be necessary.

 Bernard Malcolm Hole
 Delegate of the Civil Aviation Safety Authority 10 April 2000

 The above AD is notified in the Commonwealth of Australia Gazette on 12 April 2000.
