Overview
The Civil Aviation Regulations 1998 (CAR 1998) were enacted to ensure the safety of civil aviation within Australia and were developed under the authority of the Parliament of Australia. The regulations provide a comprehensive framework for the certification, operation, and maintenance of aircraft to ensure public safety. Part 39 of these regulations, which includes the Airworthiness Directives (ADs), specifically addresses the ongoing maintenance and inspection requirements of aircraft to mitigate safety risks. The AD for Boeing 747 Series Aeroplanes, issued by the Civil Aviation Safety Authority (CASA) delegate, is an example of the regulatory measures implemented to address identified safety issues. This particular AD, number 5 Entry Door Cutout 11/2001, was introduced in response to reports of cracks in critical structural components of the aircraft's main entry door, which could compromise the aircraft's integrity. The policy objective of this AD is to mandate specific inspection procedures to prevent potential structural failures, thereby ensuring the continued airworthiness and safety of the affected aircraft models.
Scope and Application
The Airworthiness Directive (AD) under subregulation 39.1 (1) of the Civil Aviation Regulations 1998 (CAR 1998) applies specifically to all Boeing 747 series aeroplanes, including models 747-100, -200B, -200F, -200C, -100B, -300, -100B SUD, -400, -400D, -400F, and 747SR. The AD mandates that the aircraft undergo an inspection in accordance with the technical requirements outlined in the FAA AD 2001-16-02 Amdt 39-12370. This directive was issued by a delegate of the Civil Aviation Safety Authority (CASA) in response to reports of cracks in the main entry door forward edge frame at body station 2231, which could compromise the aircraft's structural integrity. The directive became effective on 1 November 2001, with compliance required as specified in the requirement document. The AD is part of the broader legislative framework of the Civil Aviation Regulations 1998 and is applicable within the Commonwealth of Australia.
Key Provisions
The main operative sections of this Airworthiness Directive (AD) for the Boeing 747 series aeroplanes (sections 1 to 5) specify the applicability, requirement, and compliance timelines for the inspection and rectification of identified structural issues with the main entry door forward edge frame. Section 1 details the applicability of the AD to all specified Boeing 747 series aircraft. Section 2 outlines the requirement for inspecting the main entry door forward edge frame in accordance with FAA AD 2001-16-02 Amdt 39-12370, with reference to Boeing Alert Service Bulletin 747-53A2450 Revision 2. Section 3 sets the compliance date, indicating that the inspection must be completed by 1 November 2001.
This AD imposes specific obligations on the operators and owners of the Boeing 747 series aircraft. They must ensure that all applicable aircraft undergo the required inspections to identify and address any cracks in the main entry door forward edge frame. The inspections must be carried out in strict adherence to the technical requirements specified in FAA AD 2001-16-02 Amdt 39-12370. Failure to comply with these obligations could compromise the airworthiness and structural integrity of the aircraft, leading to potential safety risks.
Failure to comply with this AD may result in serious consequences. The AD clearly states that the compliance must be achieved by the specified date of 1 November 2001. Non-compliance could lead to enforcement actions by the Civil Aviation Safety Authority (CASA). The exact penalties for non-compliance are not detailed in the AD itself but may include fines, operational restrictions, or other regulatory sanctions under the Civil Aviation Act 1988 and related regulations. Ensuring adherence to the AD is crucial for maintaining the safety standards required by Australian aviation regulations.
