COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Boeing 767 Series Aeroplanes
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/B767/25 and issues the following AD under subregulation 39.1 (1) of CAR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.
AD/B767/25
Amdt 1
AlliedSignal I.P. Check Valves 3/2000
Applicability: All Boeing 767 series aircraft with Allied Signal I.P. check valves, part number 3202164-2 or -4 installed.
Requirement: Inspect applicable I.P. check valves in accordance with Boeing Alert Service Bulletin 767-36A0030 or 767-36A0030 Revision 1.
Note: FAA AD 90-01-09 also refers.
Compliance: Unless previously accomplished, at next “A” Check or within 250 flight hours of the effective date of this airworthiness directive, whichever occurs first.
This Amendment becomes effective on 23 March 2000.
Background: Failures of the engine I.P. check valve, which caused engine compressor stall, have been attributed to a manufacturing fault.
This amendment updates the AD and deletes the repetitive inspection required by the original issue of the directive.
The original issue of this Airworthiness Directive became effective on 10 August 1989.

The above AD is notified in the Commonwealth of Australia Gazette on 23 February 2000.
Overview
The Civil Aviation Regulations 1998, under the oversight of the Civil Aviation Safety Authority (CASA), were enacted to regulate airworthiness and safety standards in civil aviation within Australia. One of the specific issues these regulations address is the safety of aircraft components, particularly in the context of the Boeing 767 series. In 2000, CASA issued an amendment to an existing Airworthiness Directive (AD) concerning the Allied Signal I.P. check valves on Boeing 767 aircraft, identifying a manufacturing fault that could lead to engine compressor stalls. The policy objective of this amendment was to ensure the safe operation of affected aircraft by mandating inspections of these check valves in accordance with specified service bulletins and to eliminate repetitive inspections that were previously required. This measure aimed to maintain the safety and airworthiness of the aircraft by addressing potential engine failures due to the identified fault.
Scope and Application
This Airworthiness Directive (AD) issued under the Civil Aviation Regulations 1998, pertains specifically to all Boeing 767 series aircraft equipped with Allied Signal I.P. check valves, part numbers 3202164-2 or -4. The directive applies to these particular components within the specified aircraft models, focusing on correcting an identified unsafe condition related to manufacturing faults that could result in engine compressor stalls. The directive was issued by the delegate of the Civil Aviation Safety Authority (CASA), effective from 23 March 2000, and was subsequently notified in the Commonwealth of Australia Gazette on 23 February 2000. Compliance with the directive requires an inspection of the applicable I.P. check valves according to Boeing Alert Service Bulletin 767-36A0030 or its revision 1, with the inspection to occur either at the next “A” Check or within 250 flight hours from the effective date of the directive, whichever comes first. This requirement replaces the previous repetitive inspections stipulated by the original issue of the directive, which became effective on 10 August 1989.
Key Provisions
The Civil Aviation Regulations 1998, under Part 39 - 105, specify that the Civil Aviation Safety Authority (CASA) can issue Airworthiness Directives (AD) for aircraft safety. In this particular case, AD/B767/25 has been revoked and replaced by AD/B767/25 Amendment 1, which addresses the issue of Allied Signal I.P. check valves on Boeing 767 series aircraft. The AD mandates that all applicable Boeing 767 aircraft with the specified Allied Signal I.P. check valves (part numbers 3202164-2 or -4) must undergo inspections as per Boeing Alert Service Bulletin 767-36A0030 or its revision 1. This directive also references FAA AD 90-01-09 for additional context. The inspection must occur either at the next "A" Check or within 250 flight hours from the effective date of this directive, whichever comes first.
Operators and owners of Boeing 767 series aircraft with the specified Allied Signal I.P. check valves must ensure that the mandated inspections are carried out as stipulated in the AD. These inspections are crucial to identify and rectify any potential issues related to engine compressor stalls, which have been linked to manufacturing faults in the check valves. Failure to comply with the AD could result in the aircraft being considered unairworthy, thereby affecting its ability to operate legally and safely.
Failure to adhere to the provisions of this AD may lead to severe consequences. Specifically, operating an aircraft that has not undergone the required inspections could result in civil penalties. The maximum penalty for non-compliance with an AD under the Civil Aviation Regulations 1998 can include fines up to $21,000 for individuals and $105,000 for corporations, depending on the severity of the breach. Furthermore, the aircraft could be grounded, and its airworthiness certificate could be suspended or revoked, effectively preventing it from flying until the required inspections and necessary repairs are completed.
