Overview

The Civil Aviation Safety Regulations 1998 were enacted by the Commonwealth of Australia to ensure the safety and efficiency of civil aviation. This legislation aims to address the problem of unsafe conditions in aircraft operations by setting out detailed requirements and directives to maintain airworthiness. The Regulations were issued by the Parliament of Australia and are administered by the Civil Aviation Safety Authority (CASA). One of the key policy objectives of the Regulations is to ensure that all civil aviation activities in Australia adhere to stringent safety standards, thereby protecting the public and maintaining the integrity of the national airspace. In the context of this specific Airworthiness Directive (AD) for the SAAB SF340 Series Aeroplanes, the Regulations mandate corrective actions to address a critical issue identified in the engine bottom mounts of certain aircraft models. This directive was issued on 10 July 2003, following reports of de-bonding in the engine bottom mounts of SF340A and SF340B aircraft, which could compromise the structural integrity and safety of the aircraft. The AD requires compliance within 500 flight hours after the directive's issuance, ensuring that the necessary repairs are made promptly to mitigate safety risks.

Scope and Application

The Civil Aviation Safety Regulations 1998 (CASR 1998), specifically Part 39 - 105, pertains to Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA) delegate. This particular Airworthiness Directive (AD) applies to the SAAB SF340 Series Aeroplanes, specifically model SF340A aircraft with serial numbers ranging from 004 to 159, and model 340B aircraft with serial numbers ranging from 160 to 459. The AD mandates that specific action, as outlined in Saab Aircraft Mandatory Service Bulletin 340-71-059 dated 16 May 2003, must be undertaken to address the identified unsafe condition. This requirement must be carried out within 500 flight hours after 10 July 2003, the date on which the AD became effective. The directive is enforceable within the jurisdiction of the Commonwealth of Australia, and its provisions are detailed in the Civil Aviation Safety Regulations 1998, which have a national reach. The AD is applicable to the specified aircraft types and serial numbers, with no stated exclusions or exemptions within the scope of this directive. The AD is further detailed in the Commonwealth of Australia Gazette on 18 June 2003.

Key Provisions

The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, includes an Airworthiness Directive (AD) aimed at ensuring the safety of certain Saab SF340 series aeroplanes. The directive (AD/SF340/93) mandates specific actions to address an identified unsafe condition (section 39.1). The AD applies to Saab SF340A aircraft with serial numbers ranging from 004 to 159 and Saab SF340B aircraft with serial numbers from 160 to 459. The requirement is that these aircraft must be serviced according to Saab Aircraft Mandatory Service Bulletin 340-71-059, dated 16 May 2003. This action is necessary to mitigate the risk of de-bonding of the engine bottom mounts, which can lead to significant structural damage and safety hazards. The directive references a previous AD (LFV AD 1-192) and is effective from 10 July 2003, with compliance required within 500 flight hours of this date. The obligations imposed by this AD are clear and specific. Operators of the affected aircraft must follow the instructions provided in the Saab Aircraft Mandatory Service Bulletin 340-71-059, ensuring that the engine bottom mounts are inspected and repaired if necessary. This involves detailed checks and potentially extensive maintenance work to address any de-bonding issues and prevent further degradation of the engine support system. The AD also requires operators to ensure that the specified compliance timeframe is adhered to, meaning that any necessary repairs or inspections must be completed within 500 flight hours after the effective date of the AD. Failure to comply with these requirements can result in serious safety risks and non-compliance with regulatory standards. Breach of the AD’s requirements can have significant consequences. While the AD itself does not explicitly outline specific penalties for non-compliance, failure to adhere to an AD can lead to enforcement actions under the Civil Aviation Act 1988 and Civil Aviation Regulations 1988. These may include fines, operational restrictions, or even grounding of the aircraft until compliance is achieved. Such actions are taken to ensure that the safety of the aircraft and its occupants is not compromised. The potential for these consequences underscores the importance of adhering to the AD’s requirements and ensuring that all necessary actions are taken in a timely manner.
