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 revokes Airworthiness Directive (AD) AD/B767/179 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/B767/179
Amdt 1
Inboard Main Flap Support Bolts 9/2003
Applicability: Model 767 series aircraft, including Model 767-400ER aircraft; line numbers 1 through 879.
Requirement: Action in accordance with the technical requirements of FAA AD 2003-11-16 Amdt 39-13175.
Note: Boeing Alert Service Bulletin 767-27A0176 Revision 1 refers.
Compliance: As specified in the Requirement document, with a revised effective date of 4 September 2003.
This Amendment becomes effective on 4 September 2003.
Background: The FAA received a report indicating that an operator found one missing bolt and two loose bolts out of four bolts at the aft attachment locations on the outboard support of the inboard main flap on a B767 series aircraft. There was evidence that the bolts were not installed tightly, though when the improper installation occurred has not been determined. The outboard support for the inboard main flap cannot carry limit load with one bolt missing in the aft attachment locations. Missing, loose, or cracked bolts at this location, if not detected, could lead to loss of the inboard main flap.
Amendment 1 is issued in response to a new FAA AD, which requires a new one- time inspection and check, corrective actions if necessary, and eventual replacement of existing titanium bolts with steel bolts.
The original issue of this Airworthiness Directive became effective on 26 December 2002.
David Villiers
Delegate of the Civil Aviation Safety Authority 22 July 2003
The above AD is notified in the Commonwealth of Australia Gazette on 13 August 2003.

Overview
The Civil Aviation Safety Regulations 1998 (CASR), enacted by the Parliament of Australia, were established to regulate civil aviation safety, ensuring the safety of air travel within Australia. These regulations, under Part 39 - 105, address specific issues related to the airworthiness of aircraft and aeronautical products, providing a framework for issuing directives that aim to correct unsafe conditions. One such Airworthiness Directive, AD/B767/179, was issued to address a safety concern identified with the inboard main flap support bolts on Boeing 767 series aircraft. This directive mandates corrective actions to ensure the integrity and safety of the aircraft, reflecting the policy objective of maintaining the highest safety standards in civil aviation. The directive was issued by a delegate of the Civil Aviation Safety Authority, responding to a reported unsafe condition identified by the Federal Aviation Administration (FAA), highlighting the collaborative approach to aviation safety between Australian and international authorities.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, governs the maintenance and airworthiness of aircraft within Australia. This legislation applies to Boeing 767 series aeroplanes, including the Model 767-400ER aircraft, across all line numbers from 1 to 879. The scope of this Airworthiness Directive (AD) is to ensure the safety of these aircraft by mandating specific actions to rectify identified unsafe conditions. The directive requires compliance with the technical requirements outlined in FAA AD 2003-11-16 Amdt 39-13175, and references Boeing Alert Service Bulletin 767-27A0176 Revision 1 for further guidance. This AD became effective on 4 September 2003, superseding the original issue from 26 December 2002, and applies to the entire fleet of specified Boeing 767 aircraft within the Australian jurisdiction. It mandates a one-time inspection, corrective actions if necessary, and eventual replacement of certain bolts to prevent potential loss of the inboard main flap due to loose or missing bolts.
Key Provisions
This legislative instrument (CASR 1998, Part 39 - 105) details an amendment to an existing Airworthiness Directive (AD) concerning Boeing 767 series aircraft. The main sections of this directive include the applicability of the AD to specific models and line numbers of the aircraft (Applicability), the specific action required in response to the identified unsafe condition (Requirement), and the timeframe within which compliance must be achieved (Compliance). The AD mandates a one-time inspection and corrective action for the inboard main flap support bolts, as per the technical requirements of FAA AD 2003-11-16 Amdt 39-13175, and references Boeing Alert Service Bulletin 767-27A0176 Revision 1. Compliance with the directive is required by 4 September 2003.
The obligations imposed by this AD on the relevant parties, including aircraft operators and maintenance personnel, are to conduct a thorough inspection of the inboard main flap support bolts on Boeing 767 series aircraft, specifically those within the specified line numbers. They must follow the technical requirements outlined in the FAA AD and Boeing Alert Service Bulletin. These obligations include identifying any missing, loose, or cracked bolts and taking appropriate corrective actions, such as tightening or replacing the bolts as necessary. This ensures that the aircraft maintain their airworthiness and safety standards.
Breaching the provisions of this AD could result in severe consequences. While the legislative instrument does not explicitly outline specific offences or penalties, non-compliance with ADs generally can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions may include fines, legal proceedings, and potential grounding of the aircraft until compliance is achieved. The severity of the penalty can vary depending on the nature and extent of the non-compliance, but it is clear that adherence to ADs is critical for maintaining aviation safety standards.
The directive underscores the importance of prompt and accurate compliance with airworthiness directives to ensure the safety of civil aviation operations. The specified requirements and timeframes are designed to mitigate the risks associated with potential structural failures, thereby protecting both the aircraft and those on board. The obligations and potential consequences of non-compliance highlight the regulatory framework's role in enforcing safety standards within the aviation industry.
