AD/SF340/53 - Anti-Skid Drive Coupling

Overview

The Civil Aviation Regulations 1998, under Part 39 - 105, includes Airworthiness Directives aimed at ensuring the safety and reliability of aircraft within Australia. This particular directive, AD/SF340/53, pertains to the SAAB SF340 series aeroplanes and was enacted to address safety concerns regarding unexpected brake pressure reductions, which have led to significant incidents, including an aircraft colliding with an airport building. The directive mandates that all affected SAAB SF340A and SF340B aircraft must comply with the manufacturer's service bulletin 340-32-107 dated 18 January 1996, and aligns with Swedish AD No 1-085 R1. This was enacted by the Civil Aviation Safety Authority to ensure that all necessary actions are taken to prevent such occurrences and enhance overall aviation safety. The enactment of this directive by the Civil Aviation Safety Authority underscores the policy objective of maintaining stringent safety standards in the aviation industry. The requirement to adhere to the specified service bulletin by a specified date reflects the urgency and importance of addressing the identified safety issues. By implementing this directive, the Civil Aviation Regulations 1998 aim to prevent future incidents and ensure the continued safety and reliability of SAAB SF340 series aircraft in Australian airspace.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the application of the Airworthiness Directive (AD) concerning SAAB SF340 Series Aeroplanes, as outlined in AD/SF340/53. This regulation applies to all SAAB SF340A aircraft with serial numbers ranging from 004 to 159 and all SAAB SF340B aircraft with serial numbers from 160 to 378. The directive requires compliance with SAAB Service Bulletin 340-32-107 dated 18 January 1996, addressing unexpected brake pressure reductions which have led to significant incidents, including an aircraft colliding with an airport building. Compliance with this directive is mandatory and must be achieved prior to 30 April 1996. The scope of this regulation is limited to the specified serial numbers of the SAAB SF340A and B series aeroplanes and does not extend to other aircraft types or models outside of this specification.

Key Provisions

The primary sections of the Civil Aviation Regulations 1998, particularly under Part 39 - 105, address the specific Airworthiness Directive (AD) for SAAB SF340 Series Aeroplanes. Section AD/SF340/53 mandates that for all SAAB SF340A aircraft with serial numbers 004 through 159, and SF340B aircraft with serial numbers 160 through 378, the action specified in SAAB Service Bulletin 340-32-107 dated 18 January 1996 must be implemented unless it has already been performed. This requirement is crucial to address the known issue of unexpected brake pressure reductions that have led to incidents, including an aircraft colliding with an airport building. Compliance with this directive is mandatory and must be achieved prior to 30 April 1996. The obligations imposed by this legislation on the relevant parties, including aircraft operators and maintenance providers, are significant. They must ensure that the specified actions detailed in the SAAB Service Bulletin are completed. This includes performing any necessary inspections, repairs, or modifications to the anti-skid drive coupling as outlined in the service bulletin to mitigate the risk of brake pressure reductions. Failure to comply with these directives can result in severe consequences, as the safety of the aircraft and its occupants could be compromised. The Civil Aviation Regulations 1998 also establish clear consequences for non-compliance with the stipulated Airworthiness Directives. Any breach of the AD/SF340/53 could result in severe penalties. The specific maximum penalties for non-compliance are not detailed in the text provided, but generally, penalties can include substantial fines, and in severe cases, criminal charges against the responsible parties, including aircraft operators and maintenance personnel. The potential civil or criminal consequences underscore the importance of adhering to the directives to ensure the continued safety and airworthiness of the affected SAAB SF340 aircraft.
