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

 Boeing 767 Series Aeroplanes

 AD/B767/69
 Amdt 1

                                      Engine Bleed Air Crossover Duct  13/92 DM

 Applicability: All Boeing 767 series aircraft.

 Requirement: 1. Unless previously carried out, action IAW Boeing ASB 767-36A0041. Compliance:               Prior to 1 April 1993 or accumulation of 7,000 flight cycles, whichever occurs later.
            Note: Aircraft not involved in ETOPS operations may be eligible for an extension to the compliance requirements.

            Background: Due to a rupture of a crossover bleed air duct loss of aircraft pressurisation, bled air to the air driven hydraulic pump, wing thermal anti-icing and also, damage to the air conditioning access panels occurred. Failure of the pressurisation may force the aircraft to descend into icing conditions with no wing anti-icing capabilities.
            Amendment 1 changed Compliance by replacing 31 January 1993 with 1 April 1993 and replacing the words 'occurs first' with 'occurs later'.
