Overview

The Civil Aviation Regulations 1998, specifically Part 39, outlines the Civil Aviation Safety Authority's (CASA) mandate to issue Airworthiness Directives (AD) aimed at maintaining the safety of aircraft and aeronautical products. This legislative instrument was enacted to address the critical need to rectify any unsafe conditions identified within the aviation industry. The AD/SEATS/21/B/E Aerospace Seat - Hydrolock Pin Orientation, issued under subregulation 39.1 (1) of CAR 1998, exemplifies CASA's commitment to ensuring air safety by mandating corrective actions for specific aircraft components. The directive applies to all B/E Aerospace Skyluxe II (AA2) passenger seats, which are installed in various Airbus and Boeing aircraft series, and requires inspection and re-orientation of the Hydrolok retaining pin as per B/E Aerospace Alert Service Bulletin 25-20-2658 to prevent potential seat malfunctions. This measure was introduced following concerns about the Hydrolok pin migrating and disconnecting from the seat structure, which could lead to significant safety hazards.

Scope and Application

The Airworthiness Directive (AD) issued under the Civil Aviation Regulations 1998 applies specifically to all B/E Aerospace Skyluxe II (AA2) passenger seats installed in various aircraft, including Airbus A300, A300-600, A320, A321, A330, and A340 Series, as well as Boeing 737-800, 747-200, 747-300, 747-400, 767-200, and 767-300 Series aircraft. The directive mandates that the Hydrolok retaining pin in these seats be inspected and re-orientated in accordance with B/E Aerospace Alert Service Bulletin 25-20-2658. The requirement to comply with this AD must be met before 21 April 2002, with the directive becoming effective on 21 March 2002. This AD was issued by a delegate of the Civil Aviation Safety Authority (CASA) to address a safety concern where the Hydrolok pin can migrate and disconnect from the seat structure, potentially causing the seat back to rotate aft and obstruct the seat or exit pathway. The AD is applicable nationally within the Commonwealth of Australia, and its enforcement extends to all aircraft operators and maintenance entities subject to CASA regulations.

Key Provisions

The key sections of the Airworthiness Directive (AD) include the applicability, requirement, and compliance sections, each providing specific details about the mandate. The applicability section (a) identifies the aircraft and seats to which the directive applies, in this case, all B/E Aerospace Skyluxe II (AA2) passenger seats. These seats are noted to be installed in various aircraft models such as Airbus A300, A300-600, A320, A321, A330, and A340 Series, as well as Boeing 737-800, 747-200, 747-300, 747-400, 767-200, and 767-300 Series. The requirement section (b) mandates that the Hydrolok retaining pin must be inspected and re-orientated in accordance with B/E Aerospace Alert Service Bulletin 25-20-2658. The compliance section (c) stipulates that this action must be completed before 21 April 2002. The AD imposes several obligations on the entities it governs. Primarily, it mandates that the Hydrolok retaining pin of the specified seats must be inspected and re-orientated to ensure it does not migrate and disconnect, which could lead to unsafe conditions. This inspection and re-orientation must follow the instructions provided in the referenced B/E Aerospace Alert Service Bulletin 25-20-2658. Furthermore, the compliance date set out in the directive means that the action must be completed by the specified deadline, ensuring that the identified safety issue is addressed promptly. Breach of the requirements set out in the Airworthiness Directive can result in various civil and criminal consequences. While the specific civil penalties are not detailed in the directive, failure to comply with such directives can typically result in substantial fines, aircraft grounding, and potential revocation of airworthiness certificates. Criminal penalties could also be applicable, potentially leading to imprisonment, especially if the non-compliance results in an accident or incident that causes harm or loss of life. The exact penalties are determined by the applicable laws and regulations, but the potential severity underscores the importance of strict adherence to the AD.
