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/B767/191 Nacelle Strut Diagonal Brace Aft Pitch Load
Fitting
3/2004
Applicability: Model 767-200, -300, and 300F series aircraft, as listed in Boeing Alert Service Bulletin 767-54A0102, dated November 8, 2001.
Requirement: Action in accordance with the technical requirements of FAA AD 2004-01-02 Amdt 39-13415
Note: Boeing Alert Service Bulletin 767-54A0102 refers
Compliance: As specified in the Requirement document, with a revised effective date of 18 March 2004
This Airworthiness Directive becomes effective on 18 March 2004.
Background: This Directive requires modification of the aft pitch load fitting of the diagonal brace of the nacelle strut of each wing. This action is necessary to prevent loss of the fuse pin of the pitch load fitting due to fatigue caused by improper clearance between the fuse pin and bushing, which could result in increased loads in the wing-to-strut joints and consequent separation of the strut and engine from the wing.

Overview
The Civil Aviation Safety Regulations 1998 (CASR 1998), enacted by the Parliament of Australia, were introduced to ensure the highest standards of safety in civil aviation. This legislation, overseen by the Civil Aviation Safety Authority (CASA), aims to provide a comprehensive framework for the regulation of civil aviation activities, with the overarching policy objective of maintaining and enhancing the safety of air travel. A notable instrument under this Act is the Airworthiness Directive (AD) concerning Boeing 767 Series Aeroplanes, specifically AD/B767/191, which was issued on 4 February 2004 and became effective on 18 March 2004. This directive addresses the critical safety concern of potential loss of the fuse pin of the pitch load fitting due to fatigue, a problem identified in the nacelle strut diagonal brace aft pitch load fitting of the Model 767-200, -300, and 300F series aircraft. The AD mandates modifications to prevent increased loads in the wing-to-strut joints and consequent separation of the strut and engine from the wing, thereby ensuring the continued airworthiness of the affected aircraft.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, issued by the Civil Aviation Safety Authority (CASA) under the authority of the Civil Aviation Act 1988, pertain to ensuring the safety and airworthiness of aircraft operating in Australian airspace. This particular Airworthiness Directive applies to Boeing 767 Series Aeroplanes, specifically the Model 767-200, -300, and 300F series aircraft as identified in Boeing Alert Service Bulletin 767-54A0102 dated November 8, 2001. The directive mandates corrective action to address the unsafe condition of the nacelle strut diagonal brace aft pitch load fitting, requiring adherence to the technical specifications outlined in FAA AD 2004-01-02 Amdt 39-13415. This action is aimed at preventing the potential loss of the fuse pin due to fatigue, which could lead to significant structural failure. The directive applies to all specified aircraft within the Australian jurisdiction, and the compliance period starts from 18 March 2004, as specified in the directive document. The AD was issued by a CASA delegate and subsequently published in the Commonwealth of Australia Gazette on 25 February 2004.
Key Provisions
The Civil Aviation Safety Regulations 1998, specifically under Part 39 - 105, outline the requirements for Airworthiness Directives (ADs) concerning civil aviation safety. These directives are issued by a delegate of the Civil Aviation Safety Authority (CASA) under subregulation 39.1 (1) of the CASR 1998. The ADs mandate specific actions to correct unsafe conditions in aircraft or aeronautical products. For example, AD/B767/191, issued on 3 March 2004, applies to Boeing 767-200, -300, and 300F series aircraft. This particular directive requires modifications to the aft pitch load fitting of the nacelle strut diagonal brace to prevent loss of the fuse pin due to fatigue. The requirement is to adhere to the technical specifications outlined in FAA AD 2004-01-02 Amdt 39-13415, with a revised effective date of 18 March 2004.
The obligations imposed by this AD on the relevant parties, such as aircraft operators and maintenance organisations, include ensuring that the specified modifications are carried out in accordance with the instructions provided. The directive specifies that the required actions must be taken within the compliance timeframe set out in the requirement document, ensuring that the modifications are completed before the revised effective date. Failure to comply with these obligations can result in serious safety risks, including the potential for wing-to-strut joint separation and consequent loss of the strut and engine from the wing.
Non-compliance with the provisions of the AD can lead to significant consequences. The Civil Aviation Safety Regulations 1998 establish that failure to adhere to an AD can result in civil penalties. The specific penalties for non-compliance are not detailed in the excerpt, but generally, these may include fines and other administrative actions. Additionally, failure to comply with an AD can result in criminal charges if the non-compliance is deemed to have caused an aviation accident or serious safety incident. In such cases, the maximum penalties can be severe, reflecting the seriousness of endangering public safety and the integrity of civil aviation operations. Therefore, it is crucial for all relevant parties to understand and meet the requirements set out in the AD to ensure continued airworthiness and safety compliance.
