COMMONWEALTH OF AUSTRALIA (Civil Aviation Safety Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
On the effective date specified below, and for the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/B767/14 and issues the following AD under subregulation 39.1 (1) of CASR 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 or aeronautical product 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.
Boeing 767 Series Aeroplanes
AD/B767/14
Amdt 1
Fin Access Door 1/2005
Applicability: All models.
Requirement: Action in accordance with Boeing S.B. 767-52-0042 Rev 02 or later FAA approved revision.
Note: FAA AD 86-19-07 refers.
Compliance: Prior to 30 November 1987.
This Amendment becomes effective on 20 January 2005.
Background: This modification is to ensure that the vertical fin will not fail in the event of rupture of the aft pressure bulkhead.
This amendment is issued to update the referenced service bulletin revision status. All Australian registered aircraft should have already complied with this AD. The amendment is issued so that no confusion will occur in the future about which revision of the service bulletin should have been used to accomplish the modification.

Overview
The Civil Aviation Safety Regulations 1998, as amended through the legislative instrument F2006B03316, address the issue of ensuring the safety of civil aviation by providing regulatory oversight and issuing airworthiness directives. This particular legislative instrument amends a previous Airworthiness Directive (AD/B767/14) concerning Boeing 767 Series aeroplanes, specifically focusing on the fin access door to prevent failures in the vertical fin due to a rupture of the aft pressure bulkhead. Enacted by the Civil Aviation Safety Authority (CASA), this amendment serves to clarify and update the compliance requirements, ensuring that Australian registered aircraft maintain the necessary safety standards as specified by the Federal Aviation Administration (FAA). The overarching policy objective is to mitigate risks associated with aircraft safety, thereby enhancing the overall safety of civil aviation operations in Australia.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, pertains to Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA) to ensure the safety of aircraft within Australia. The scope of this legislation applies to all Boeing 767 Series aeroplanes, a widely used commercial aircraft model, ensuring that they meet the specified safety standards. The directive, in this case, mandates compliance with Boeing Service Bulletin 767-52-0042 Rev 02 or a later version approved by the Federal Aviation Administration (FAA). The directive is aimed at preventing vertical fin failure in the event of an aft pressure bulkhead rupture, ensuring the structural integrity and safety of the aircraft. The geographic reach of this regulation is national, encompassing all Australian registered aircraft, thereby extending the safety measures mandated by the FAA to the Australian aviation industry. There are no stated exclusions or exemptions in this directive, implying that all affected aircraft must comply with the specified requirements. The regulation's application can be extended or further detailed through subordinate instruments, although the primary directive is clear and specific in its requirements and applicability.
Key Provisions
The Civil Aviation Safety Regulations 1998, specifically under Part 39 - 105, address Airworthiness Directives (AD) for aircraft safety. The relevant AD in focus is AD/B767/14 Amendment 1, which pertains to Boeing 767 Series Aeroplanes. This AD mandates actions to ensure the safety of the aircraft, particularly in relation to the fin access door. It specifies that the modification must be carried out in accordance with Boeing Service Bulletin 767-52-0042 Revision 02 or any subsequent revisions approved by the Federal Aviation Administration (FAA). The directive references FAA AD 86-19-07 and stipulates that the required action must be completed prior to a specified date, in this case, before 30 November 1987. The amendment became effective on 20 January 2005, as signed by David Villiers, a delegate of the Civil Aviation Safety Authority.
The obligations under this AD require all operators of Boeing 767 aircraft to ensure compliance with the specified service bulletin. This involves making necessary modifications to the vertical fin to prevent failures in the event of a rupture in the aft pressure bulkhead. Operators must adhere strictly to the instructions provided in the service bulletin to ensure the safety and airworthiness of their aircraft. The AD was issued to clarify the revision status of the service bulletin and to prevent any future confusion regarding which version should be implemented.
Failure to comply with the requirements of this AD can result in serious safety implications, potentially leading to catastrophic failure of the vertical fin in the event of an aft pressure bulkhead rupture. While the regulations do not explicitly state penalties for non-compliance, the Civil Aviation Safety Authority (CASA) has the authority to enforce compliance through various means, including issuing notices, imposing fines, or taking legal action. The severity of the consequences underscores the importance of adhering to the AD to maintain the safety and airworthiness of the aircraft.
