AD/B747/235 Amdt 1 - Fuselage Skin at BS 980 Drag Splice Fitting

Overview

The Civil Aviation Regulations 1998 (CAR 1998) were enacted to provide comprehensive regulations governing civil aviation in Australia. One of the key components of this legislation is Part 39, which includes the Civil Aviation Safety Authority Schedule of Airworthiness Directives. These directives are crucial in ensuring that aircraft and aeronautical products meet the necessary safety standards. The problem or gap that this legislation addresses is the need for consistent and stringent safety measures to be implemented across the civil aviation industry in Australia. The CAR 1998 was enacted by the Australian Parliament to establish a framework for the regulation of civil aviation. The policy objective behind the enactment of CAR 1998 is to ensure the safety and efficiency of civil aviation in Australia by setting out detailed regulations and standards that must be adhered to by all stakeholders in the industry. This includes the requirement for airworthiness directives, such as the one outlined above, which are issued by the Civil Aviation Safety Authority to address specific safety concerns and ensure that corrective actions are taken to maintain the airworthiness of aircraft.

Scope and Application

The Airworthiness Directive issued under the Civil Aviation Regulations 1998 applies specifically to all Model 747 series aircraft. This legislation is enacted to ensure the safety and airworthiness of civil aviation within the Commonwealth of Australia. The directive mandates that the action specified in the requirement section must be taken in relation to the applicable aircraft under the prescribed circumstances, following the instructions set out in the requirement section, and within the timeframe mentioned in the compliance section. The AD was issued by a delegate of the Civil Aviation Safety Authority (CASA) to address safety concerns regarding fatigue cracking of the fuselage skin adjacent to the BS 980 drag splice fitting, which could compromise the structural integrity of the aircraft. Compliance with this directive is imperative to maintain the safety standards as required by the Civil Aviation Regulations 1998. The AD was published in the Commonwealth of Australia Gazette and became effective on 27 December 2001.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, section 105, outlines the Civil Aviation Safety Authority (CASA) schedule of Airworthiness Directives (AD). This particular AD, AD/B747/235 Amendment 1, pertains to all Model 747 series aircraft. The directive was issued by a CASA delegate, David Alan Villiers, on 16 November 2001, in response to new safety requirements by the Federal Aviation Administration (FAA). The AD requires an inspection of the fuselage skin at the BS 980 drag splice fitting to detect and correct any fatigue cracking that could compromise the structural integrity of the fuselage. The obligations under this AD are clear and specific. All Model 747 series aircraft must undergo inspections as stipulated in FAA AD 2001-22-04 Amendment 39-12483. These inspections should follow the technical requirements outlined in the FAA directive, and references to Boeing Service Bulletins 747-53A2444 Revision 1 and Revision 2 are provided for additional guidance. The compliance with these directives must be achieved by 27 December 2001, as specified in the requirement document, although the AD itself became effective on 27 December 2001. Failure to comply with the AD may lead to serious consequences. The AD is designed to ensure the safety of the aircraft and its occupants by addressing potential structural weaknesses that could result in catastrophic failures. While the Civil Aviation Regulations 1998 do not explicitly state penalties for non-compliance with ADs, non-compliance could lead to enforcement actions under other sections of the Civil Aviation Act 1988, including fines and imprisonment. Additionally, airlines and operators may face operational restrictions or even grounding of the aircraft in question, leading to significant financial and reputational damage. Therefore, adherence to the AD is not only a legal requirement but also a critical safety measure.
