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/B747/207 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 747 Series Aeroplanes
AD/B747/207
Amdt 1
Nacelle Diagonal Brace Steel Attachment Fittings
10/2004
Applicability: Model 747 series aircraft equipped with General Electric Model CF6-45 or -50 engines, or Pratt & Whitney JT9D-3, -7, or -70 series engines, having steel attachment fittings of the diagonal brace to the nacelle struts.
Requirement: Perform a detailed visual inspection in accordance with the technical requirements of FAA AD 2001-16-08 Amendment 39-12376.
Compliance: As specified in the requirement document for the initial and repetitive inspections.
This Amendment becomes effective on 30 September 2004.
Background: The original issue of this AD was raised in response to a report of a fatigue crack in one of the steel attachment fittings of the diagonal brace to nacelle strut. At that time FAA AD 99-09-11 referred.
Subsequent to this, the FAA released AD 2001-16-08 Amdt 39-12376 which superseded FAA AD 99-09-11. This amendment is issued as a result of the new FAA AD.

Overview
The Civil Aviation Safety Regulations 1998 (CASR), specifically Part 39 - 105, addresses the ongoing safety and maintenance of aircraft operating within Australia. This legislation was enacted to ensure that aircraft meet certain safety standards and to provide a framework for the Civil Aviation Safety Authority (CASA) to mandate specific actions to rectify safety issues as they arise. One such action is the issuance of Airworthiness Directives (ADs), which are regulatory measures designed to address identified safety concerns. The AD in question, AD/B747/207 Amendment 1, focuses on Boeing 747 series aircraft equipped with certain engine types, requiring detailed visual inspections of steel attachment fittings in the nacelle struts. This directive was introduced in response to a reported fatigue crack in these fittings, necessitating compliance with updated Federal Aviation Administration (FAA) guidelines to ensure continued airworthiness.
The AD/B747/207 Amendment 1 was issued by the CASA delegate, David Villiers, on 19 August 2004, and it became effective on 30 September 2004. This legislative instrument aims to maintain and enhance the safety standards of civil aviation by ensuring that specific maintenance actions are undertaken to mitigate potential risks. The policy objective is to prevent incidents related to the identified unsafe condition, thereby safeguarding the safety of passengers, crew, and the general public.
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). These directives apply to particular aircraft models and aeronautical products to ensure compliance with safety standards. For instance, Airworthiness Directive AD/B747/207 Amendment 1 applies to Boeing 747 series aeroplanes equipped with certain engine models and having specific steel attachment fittings in the nacelle struts. The directive mandates detailed visual inspections in accordance with specified technical requirements, as set out by the Federal Aviation Administration (FAA). This regulatory action is aimed at correcting an identified unsafe condition, in this case, a fatigue crack in the steel attachment fittings. The directive’s applicability is geographically bounded to the Commonwealth of Australia, and it comes into effect on the date specified, which is 30 September 2004. The directive is issued under the authority delegated to CASA, ensuring that the required safety measures are implemented to maintain airworthiness standards.
Key Provisions
The Civil Aviation Safety Regulations 1998, specifically under Part 39 - 105, mandates that the Civil Aviation Safety Authority (CASA) must issue Airworthiness Directives (ADs) to ensure the safety of aircraft in operation. Section 39.1 (1) of the regulations allows the CASA delegate to issue these directives. In this instance, the CASA delegate has revoked the previous AD/B747/207 and issued a new one, AD/B747/207 Amendment 1, effective from 30 September 2004. This new directive applies to Boeing 747 series aeroplanes equipped with certain engines and having specific steel attachment fittings on the nacelle struts.
The AD requires operators of the specified aircraft to perform a detailed visual inspection in accordance with the technical requirements outlined in FAA AD 2001-16-08 Amendment 39-12376. This inspection must be conducted under the conditions specified in the directive, and the compliance schedule must be followed as mentioned in the requirement document for both initial and repetitive inspections. This directive is a response to a reported fatigue crack in one of the steel attachment fittings of the diagonal brace to the nacelle strut, and it supersedes the previous FAA AD 99-09-11.
Operators of the affected aircraft must adhere to the obligations outlined in the AD. This includes ensuring that all inspections are conducted by qualified personnel and in accordance with the specified technical requirements. The AD mandates that inspections must be performed at the intervals specified within the requirement document, ensuring the safety and airworthiness of the aircraft. Failure to comply with these obligations could result in the aircraft being deemed unairworthy, leading to potential grounding and legal consequences.
The AD also imposes penalties for non-compliance with the specified requirements. Although the exact penalties are not detailed within the text, non-compliance with CASA directives can result in significant civil or criminal penalties, including fines and potential imprisonment for individuals. The severity of the penalties can vary depending on the extent and impact of the non-compliance. Operators are therefore strongly advised to ensure strict adherence to the AD to avoid any legal repercussions.
