Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, form a comprehensive legal framework governing civil aviation safety. Part 39 - 105 of these regulations pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, which are critical for ensuring the safe operation of aircraft within Australian airspace. One such directive, AD/B747/234, was issued to address the identified issue of fatigue cracking in the aft pressure bulkhead of Boeing 747 series aeroplanes, as reported by the Federal Aviation Administration. This directive was introduced to rectify the unsafe condition and maintain the airworthiness of these aircraft, ensuring they meet the stringent safety standards set by the Civil Aviation Safety Authority.
Scope and Application
The Civil Aviation Regulations 1998, under Part 39, Section 105, encompasses an Airworthiness Directive (AD) specifically pertaining to Boeing 747 series aircraft. This legislation applies to all aircraft within the mentioned series, as identified in Boeing Alert Service Bulletin 747-53A2425. The AD mandates actions to rectify an identified unsafe condition, namely fatigue cracking in the upper half of the aft pressure bulkhead, and is issued under the authority of the Civil Aviation Safety Authority (CASA) delegate. The directive requires compliance with the technical inspection standards outlined in FAA AD 2000-12-19 Amdt39-11797, with specific compliance dates set forth in the requirement document for both initial and repetitive inspections, effective as of 2 November 2000. The AD became effective on 2 November 2000 and was subsequently notified in the Commonwealth of Australia Gazette on 4 October 2000.
Key Provisions
The Airworthiness Directive (AD) B747/234 pertains specifically to Boeing 747 series aircraft and mandates inspections of the aft pressure bulkhead to address fatigue cracking (section 11/2000). The applicability section (Model 747 series aircraft, as listed in Boeing Alert Service Bulletin 747-53A2425) identifies the aircraft subject to the directive. The requirement section specifies that inspections must be conducted in accordance with the technical requirements of FAA AD 2000-12-19 Amdt39-11797. The compliance section outlines the schedule for the initial and repetitive inspections, with a revised effective date of 2 November 2000. The directive itself becomes effective on 2 November 2000.
The AD imposes clear obligations on the operators of Boeing 747 series aircraft. Specifically, they must conduct the required inspections of the aft pressure bulkhead as specified in the FAA AD 2000-12-19 Amdt39-11797. The directive requires adherence to the outlined technical requirements and compliance with the specified schedule for both initial and repetitive inspections. Failure to comply with these requirements could result in safety risks and non-compliance with regulatory standards.
Failure to comply with the provisions of this Airworthiness Directive may result in serious safety implications and legal consequences. The Civil Aviation Safety Authority (CASA) is responsible for enforcing compliance, and non-compliance could lead to enforcement actions. While the specific penalties for breaches are not detailed within this AD, violations of aviation regulations can result in significant civil or criminal penalties, including fines and potential grounding of the aircraft. These measures are intended to ensure that the identified safety issues are adequately addressed to maintain the airworthiness of the affected aircraft.
