AD/B747/44 Amdt 1 - Inboard Elevator Control Rods and Aft Quadrant

Overview

The Civil Aviation Regulations 1998, as amended by F2006B03225, were enacted to enhance aviation safety through the establishment of stringent airworthiness directives and compliance requirements. This legislative instrument, introduced by the Australian Parliament, specifically targets the Boeing 747 Series Aeroplanes, focusing on the inboard elevator control rods and aft quadrant to ensure operational safety and reliability. The regulation addresses a gap in ensuring that the aircraft meet international safety standards, referencing the Federal Aviation Administration's (FAA) Airworthiness Directive 90-25-10 Amendment 39-6822 as the technical basis for compliance. The policy objective is to mandate adherence to specific maintenance and inspection protocols to mitigate potential safety risks associated with the inboard elevator control rods and aft quadrant of the Boeing 747 Series Aeroplanes.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, which includes the Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to all Boeing 747 series aeroplanes with line numbers ranging from 001 to 635. This regulation mandates compliance with the technical requirements outlined in FAA AD 90-25-10 Amendment 39-6822, pertaining to the inboard elevator control rods and aft quadrant. The directive references Boeing Alert Service Bulletin 747-27A2253 Revision 4, which provides further guidance. Compliance with this directive is mandatory, with an effective date of 7 January 1991. The scope of the legislation is limited to the specified aircraft models and requires adherence to the detailed requirements set out by the Federal Aviation Administration, as referenced and amended. The directive ensures that the modifications and actions specified are implemented to maintain the airworthiness of the affected aircraft within the Australian jurisdiction.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the Airworthiness Directives for the Boeing 747 Series Aeroplanes. Section AD/B747/44 Amendment 1 pertains to the inboard elevator control rods and aft quadrant. This directive applies to Boeing 747 aeroplanes with line numbers ranging from 001 through 635 (section 2). The requirement is for compliance with the technical specifications outlined in FAA AD 90-25-10 Amendment 39-6822 (section 3). This requirement is referenced in Boeing Alert Service Bulletin 747-27A2253 Revision 4 (section 3 note). Compliance must be achieved according to the specifications provided in the requirement document, with an effective date set for 7 January 1991 (section 4). Operators of Boeing 747 aeroplanes within the specified line numbers must ensure that the inboard elevator control rods and aft quadrant meet the technical requirements as outlined in the FAA AD 90-25-10 Amendment 39-6822. This involves inspecting, maintaining, or replacing parts as necessary to meet the standards set forth in the requirement document. The compliance date of 7 January 1991 must be strictly adhered to, and any actions taken to achieve compliance must be documented and verified to ensure that the aircraft meet the necessary airworthiness standards. Failure to comply with the provisions of AD/B747/44 Amendment 1 may result in significant consequences. The Civil Aviation Regulations 1998 establish that non-compliance with airworthiness directives can lead to severe penalties. While specific penalties are not detailed in the legislative instrument, non-compliance with airworthiness directives generally results in severe civil and criminal penalties, including fines and potential imprisonment. The Civil Aviation Safety Authority (CASA) has the authority to enforce these regulations, and significant breaches can lead to grounding of the aircraft, suspension of operations, and other enforcement actions deemed necessary to ensure compliance and maintain aviation safety standards. Additionally, the safety and operational integrity of the Boeing 747 aeroplanes are paramount, and any deviation from the specified airworthiness directives can jeopardise flight safety. Therefore, operators must take proactive measures to ensure that all maintenance and modifications are performed in accordance with the stipulated requirements. CASA regularly conducts audits and inspections to ensure compliance, and any evidence of non-compliance can lead to immediate corrective actions and further investigation. Thus, it is crucial for operators to maintain meticulous records and documentation to demonstrate compliance and to swiftly address any issues that may arise.
