AD/A320/25 Amdt 2 - Elevator Servo Controls

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, establish a comprehensive framework to regulate civil aviation safety. Among these regulations, Part 39 - 105 specifically addresses the issuance of airworthiness directives, ensuring that aircraft maintenance and operational standards are rigorously upheld. One such directive, AD/A320/25, pertains to Airbus A320 series aircraft and mandates specific actions to prevent in-flight elevator vibration. This directive aligns with the broader policy objective of maintaining the highest safety standards within Australia's civil aviation sector by implementing technical requirements and compliance measures that address known issues with aircraft components. The legislative instrument F2006B01916 amends the existing directive to enhance elevator servo control inspections for Airbus A320 series aeroplanes. This amendment, introduced to rectify the identified problem of elevator deflection and actuator issues, requires adherence to the technical specifications set forth by the French Directorate General for Civil Aviation (DGAC). By incorporating these measures, the Civil Aviation Safety Authority aims to mitigate risks associated with in-flight elevator vibrations, thereby contributing to the overall safety and reliability of air travel within Australia.

Scope and Application

The Civil Aviation Regulations 1998, as amended by PART 39 - 105, applies specifically to all Airbus A320 series aircraft operating within Australia. This legislation is overseen by the Civil Aviation Safety Authority (CASA) and is intended to ensure the airworthiness of these aircraft by imposing strict technical requirements and compliance protocols. The requirements outlined in this particular directive, AD/A320/25 Amendment 2, necessitate actions that adhere to the technical specifications set by the French Civil Aviation Authority (DGAC) through AD 91-27-202(B)R2. Additionally, the directive references several Airbus Service Bulletins (SB A320-27-1043 R1, SB A320-27-1048, and SB A320-55-1015 R1) which provide further guidance and specifications necessary for compliance. The directive mandates repetitive elevator deflection checks and elevator actuator inspections to mitigate the risk of in-flight elevator vibration, a critical safety measure. Compliance with these directives is mandatory unless the specified actions have already been carried out as per the requirement documents, ensuring that all Airbus A320 series aircraft maintain the highest safety standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority, outlines various Airworthiness Directives (ADs) to ensure the safety of aircraft. One such directive, AD/A320/25 Amendment 2, pertains to the Airbus Industrie A319, A320, and A321 series aeroplanes, with a focus on the elevator servo controls (Section 1). This AD mandates that all Airbus A320 series aircraft must comply with the technical requirements of DGAC AD 91-27-202(B)R2 (Section 2). It also references related Airbus Industrie Service Bulletins (SB) A320-27-1043 R1, SB A320-27-1048, and SB A320-55-1015 R1 for additional compliance details (Section 2). The directive imposes several obligations on the operators of Airbus A320 series aircraft. Firstly, repetitive elevator deflection checks and elevator actuator inspections are mandatory to prevent in-flight elevator vibration (Section 2). These inspections must be carried out unless they have already been completed as specified in the Requirement Document (Section 2). The AD also extends the inspection time of the elevator actuator spherical bearings if they have been modified and includes provisions for crediting compliance with the Airbus Industrie SB A320-27-1043 initial issue (Section 2). Non-compliance with the AD/A320/25 Amendment 2 can lead to severe consequences. While the regulations do not specify exact penalties, non-compliance with airworthiness directives is generally considered a serious breach of aviation safety standards (Section 3). Violators may face enforcement actions by the Civil Aviation Safety Authority, which can include fines, operational restrictions, or even grounding of the aircraft. The severity of the penalties will depend on the nature and extent of the non-compliance, and the authority may consider various factors, including the potential risk to flight safety and the operator's history of compliance (Section 3).
