COMMONWEALTH OF AUSTRALIA (Civil Aviation Safety Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (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/B767/192 Aft Pressure Bulkhead Web 5/2004
Applicability: Model 767-200 and -300 series aircraft, line numbers 1 through 423.
Requirement: Inspect in accordance with the technical requirements of FAA AD 2004-05-16 Amdt 39-13511.
Note: Boeing Alert Service Bulletin 767-53A0087 refers.
Compliance: As specified in the Requirement document, with a revised effective date of 13 May 2004.
This Airworthiness Directive becomes effective on 13 May 2004.
Background: Reports were received of cracks in the aft pressure bulkhead web to pressure chord joint on Models 737 and 747 aircraft. Due to the structural similarity, inspection has been extended to the Model 767 aircraft. Cracks in the aft pressure bulkhead web can result in rapid decompression and/or damage to, or interference with, control systems that penetrate the dome.

Overview
The Civil Aviation Safety Regulations 1998 (CASR) are a comprehensive set of rules established to ensure the safety of civil aviation in Australia. Enacted by the Parliament of Australia, these regulations were introduced to address the need for stringent safety measures and standards in the aviation industry, aiming to protect passengers, crew, and the general public from potential hazards. One aspect of these regulations is the issuance of Airworthiness Directives (ADs) by the Civil Aviation Safety Authority (CASA), which mandate corrective actions to address identified safety issues. The ADs are designed to mitigate risks by enforcing necessary inspections, repairs, or modifications to aircraft, ensuring they meet the required safety standards. This legislative framework underscores the commitment to maintaining high safety standards in Australia's civil aviation sector, reflecting the policy objective of safeguarding public safety and maintaining the integrity of the aviation industry.
Scope and Application
The Airworthiness Directive (AD) issued under the Civil Aviation Safety Regulations 1998 pertains specifically to the Boeing 767-200 and -300 series aircraft, with line numbers ranging from 1 through 423. The directive mandates an inspection of the aft pressure bulkhead web, in accordance with the technical requirements outlined in FAA AD 2004-05-16 Amdt 39-13511, due to reported instances of cracks in similar aircraft models which could lead to catastrophic failures. The directive applies nationally within the Australian jurisdiction and requires compliance from all aircraft operators and maintenance providers handling the specified Boeing 767 models. The directive became effective on 13 May 2004, as stipulated in the compliance section, and was published in the Commonwealth of Australia Gazette on 21 April 2004. The AD extends to any entity or individual operating these aircraft within Australian airspace, with no stated exclusions or exemptions.
Key Provisions
The key provision of the Civil Aviation Safety Regulations 1998, specifically under Part 39 - 105, is the issuance of Airworthiness Directives (AD) by a delegate of the Civil Aviation Safety Authority (CASA) to ensure the safe operation of aircraft. In this case, AD/B767/192 is issued for Boeing 767 Series Aeroplanes to address potential structural issues with the aft pressure bulkhead web (section 39.1(1)). The directive mandates specific actions to be taken in relation to the mentioned aircraft model and line numbers (applicability), which must be carried out in accordance with the technical requirements outlined in the directive (requirement). The compliance date is specified to ensure timely implementation of these safety measures.
The AD imposes several obligations on the parties governed by it. Operators of Boeing 767-200 and -300 series aircraft, specifically those within line numbers 1 through 423, must conduct inspections of the aft pressure bulkhead web as per the technical requirements detailed in FAA AD 2004-05-16 Amdt 39-13511. This inspection must be completed by 13 May 2004, as stated in the compliance section. Failure to comply with these requirements can lead to safety issues such as rapid decompression and damage to control systems, posing significant risks to flight safety.
Failure to comply with the AD can lead to serious civil and criminal consequences. Under the Civil Aviation Act 1988, non-compliance with an Airworthiness Directive can result in civil penalties, including fines. The maximum penalty for contravening these regulations can be substantial, often reaching into the millions of dollars, depending on the severity and impact of the non-compliance. Additionally, there may be criminal penalties for individuals or companies found guilty of willfully disregarding the AD, which could include imprisonment. These stringent measures underscore the importance of adhering to the AD to ensure the highest standards of aviation safety.
