Wing Front Spar Web 11/2003
Applicability: Model 747 series aircraft, as listed in Boeing Service Bulletin 747-57A2311 Revision 2, dated 21 February 2002.
Requirement: Inspect in accordance with the technical requirements of FAA AD 2003-16-12 Amdt 39-13265.
Note: Boeing Alert Service Bulletins 747-57A2311, 747-57A2311Revision 1, including Appendices A and B, and 747-57A2311 Revision 2 refer.
Compliance: As specified in the Requirement document, with a revised effective date of 30 October 2003.
This Amendment becomes effective on 30 October 2003.
Background: The FAA required inspections to detect and correct fatigue cracking of the wing front spar web, which could result in fuel leaking onto an engine and a consequent fire.
Amendment 1 corrected compliance repeat inspection frequency.
Amendment 2 is issued in response to a new FAA AD, which changes applicability, changes certain compliance times, adds certain new requirements, and introduces an optional modification.
Amendment 1 of this Airworthiness Directive became effective on 6 September 2001. The original issue of this Airworthiness Directive became effective on 12 July 2001.

Overview
The Civil Aviation Safety Regulations 1998 (CASR), enacted by the Parliament of Australia, are designed to regulate the airworthiness of aircraft operating in Australian airspace. The regulations are essential in ensuring the safety of civil aviation within the country, addressing gaps in previous aviation safety legislation. One specific legislative instrument under CASR, F2006B03143, pertains to Airworthiness Directives, such as the AD/B747/246 Amdt 2, which was issued by the Civil Aviation Safety Authority (CASA) in response to a safety issue identified with Boeing 747 series aircraft. This Airworthiness Directive was enacted to address the risk of fatigue cracking in the wing front spar web of these aircraft, which could potentially lead to fuel leaks and engine fires. The policy objective of this directive is to ensure the continued airworthiness and safety of the specified aircraft models by mandating specific inspection and maintenance protocols.
Scope and Application
The Civil Aviation Safety Regulations 1998, as amended, govern the safety standards for civil aviation in Australia, with Part 39 - 105 focusing on Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA). These directives apply specifically to the operators of Boeing 747 series aircraft as identified in Boeing Service Bulletin 747-57A2311 Revision 2, dated 21 February 2002. The legislation mandates the inspection of the wing front spar web in accordance with the technical requirements outlined in FAA AD 2003-16-12 Amdt 39-13265, in order to address the risk of fatigue cracking which could lead to fuel leaks and potential engine fires. Compliance with this directive is mandatory and must be achieved by 30 October 2003, as specified in the requirements. The directive was initially issued to ensure safety, with Amendment 1 taking effect on 6 September 2001, and Amendment 2, which updates the directive based on new FAA requirements, becoming effective on 30 October 2003.
Key Provisions
The Civil Aviation Safety Regulations 1998, under PART 39 - 105, establish specific directives for ensuring the airworthiness of aircraft within Australia, including the Boeing 747 series. This particular Airworthiness Directive (AD) pertains to the inspection of the wing front spar web of Boeing 747 series aeroplanes, as outlined in section 1 (1) of the regulations. The AD mandates that the specified action must be taken in accordance with the detailed requirements set forth in the directive, which include inspecting the aircraft in line with the technical requirements of FAA AD 2003-16-12 Amdt 39-13265. The directive specifies the compliance timeframe, which has been revised to 30 October 2003, and applies to all model 747 series aircraft as listed in Boeing Service Bulletin 747-57A2311 Revision 2, dated 21 February 2002.
Operators of Boeing 747 series aircraft are required to adhere to the specified inspection protocols to ensure the airworthiness of their aircraft. This involves conducting inspections as per the technical requirements mentioned in FAA AD 2003-16-12 Amdt 39-13265. The inspection must be performed by qualified personnel, and any findings must be documented accurately. These obligations are designed to identify and rectify potential safety issues, particularly fatigue cracking of the wing front spar web, which could lead to fuel leakage and subsequent fire hazards. Compliance with these directives is mandatory and must be maintained to ensure the safety of the aircraft and its passengers.
Failure to comply with the requirements set out in the AD can result in serious consequences. According to the regulations, non-compliance may lead to enforcement actions by the Civil Aviation Safety Authority (CASA). The penalties for breaches can include substantial fines and potential legal actions. The severity of the penalty can vary depending on the nature and extent of the non-compliance. In some cases, CASA may also impose operational restrictions on the aircraft until the required actions are completed and verified. It is imperative for aircraft operators to ensure that they meet all the stipulated requirements to avoid these penalties and maintain the safety standards required by the regulations.
