Overview

The Civil Aviation Regulations 1998 (CAR 1998) were enacted to regulate civil aviation safety and ensure the safe operation of aircraft in Australian airspace. Specifically, Part 39 - 105 of these regulations addresses Airworthiness Directives, which are legally binding orders issued by the Civil Aviation Safety Authority (CASA) to correct unsafe conditions in aircraft. The problem or gap this legislation addresses is the need to mandate specific actions to mitigate identified safety risks that may not be covered under standard regulatory provisions. Enacted by the Parliament of Australia, the policy objective of the CAR 1998 is to protect public safety by enforcing stringent safety standards and protocols for civil aviation operations. In the case of the Airworthiness Directive for Bombardier (Canadair) CL-600 (Challenger) Series Aeroplanes, the directive was issued to address a specific issue of false fire warnings caused by fluid contamination in the Fire and Overheat Control Unit, ensuring that corrective measures are implemented to maintain the airworthiness of affected aircraft.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandate the issuance of Airworthiness Directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safe operation of aircraft within Australian airspace. These directives apply to specific types of aircraft and components, such as the Bombardier (Canadair) CL-600 (Challenger) Series Aeroplanes, and are designed to address identified safety concerns. The AD for the CL-600-2B19 “Regional Jet” aircraft with serial numbers 7003 through 7067 and 7069 through 7422 mandates the installation of protective sealing tape to the Fire and Overheat Control Unit to mitigate the risk of false fire warnings. Compliance with this directive must occur within 250 flying hours or 30 days after the AD's effective date, whichever is sooner. The directive is enforceable across Australia, extending the regulatory reach of the Commonwealth to ensure adherence to safety standards among operators of these aircraft within the nation's jurisdiction. The AD is detailed and specific, providing clear instructions based on findings from investigations into safety issues, such as fluid contamination in the control unit, as evidenced by Transport Canada's corresponding AD CF-2000-35.

Key Provisions

The Civil Aviation Regulations 1998, Part 39 - 105, under the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, includes specific requirements for the Bombardier (Canadair) CL-600 (Challenger) series aeroplanes. This particular directive, AD/CL-600/41 3/2001DM, applies to CL-600-2B19 "Regional Jet" aircraft with serial numbers ranging from 7003 through 7067, and 7069 through 7422. The directive mandates the installation of protective sealing tape to the Fire and Overheat Control Unit, in accordance with Bombardier Alert Service Bulletin A601R-26-017, Revision A (section 3(a)). This action is necessary to address the issue of false engine and Auxiliary Power Unit (APU) fire warnings, which have been traced to fluid contamination in the fire and overheat control unit (section 3(b)). The directive stipulates that this installation must be completed within 250 flying hours or 30 days from the effective date of the directive, whichever comes first (section 3(c)). The entities governed by this AD, specifically those owning or operating the affected CL-600-2B19 aircraft, have an obligation to ensure that the required modifications are implemented within the specified timeframe. They must follow the instructions detailed in the Bombardier Alert Service Bulletin A601R-26-017, Revision A, to ensure the installation of the protective sealing tape is done correctly and effectively. Failure to comply with this AD may result in the aircraft not meeting the required airworthiness standards, potentially leading to operational restrictions or grounding until the required modifications are completed. In terms of legal consequences, the Civil Aviation Regulations 1998 do not explicitly outline penalties for non-compliance with Airworthiness Directives within the provided text. However, it is understood that failure to adhere to such directives can result in severe repercussions, including potential enforcement actions by the Civil Aviation Safety Authority (CASA). These actions may include fines, suspension or revocation of airworthiness certificates, and other regulatory penalties. Such measures are designed to ensure that aircraft operate within safe and compliant parameters, thereby protecting public safety and maintaining the integrity of the aviation industry.
