Overview

The Civil Aviation Regulations 1998 (CAR 1998) were enacted in 1998 and serve to regulate civil aviation safety in Australia. These regulations were introduced to establish a comprehensive framework governing all aspects of civil aviation, ensuring safety and security for all individuals involved. This includes regulations pertaining to airworthiness, licensing, and operational standards for aircraft, personnel, and organisations within the Australian civil aviation sector. The CAR 1998 is administered by the Civil Aviation Safety Authority (CASA), an agency of the Australian Government responsible for regulating civil aviation safety. The policy objective behind these regulations is to maintain the highest possible safety standards in civil aviation, protecting the public, crew, and passengers from potential risks and hazards associated with air travel. In the context of the Bombardier (Canadair) CL-600 (Challenger) Series Aeroplanes, the CAR 1998 incorporates Airworthiness Directives (AD) issued by CASA to address specific safety concerns. For instance, AD/CL-600/43, effective from 6 September 2001, mandates the replacement of cargo compartment smoke detectors in specific Bombardier CL-600-2B19 "Regional Jet" aeroplanes due to issues with false "CARGO SMOKE" warnings. This AD was issued following Transport Canada's advisory on the susceptibility of the smoke detectors to dirt, condensation, and electromagnetic interference. The directive aims to rectify the unsafe condition, ensuring the integrity of the Engine Indication and Crew Alerting System (EICAS) and enhancing overall flight safety.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the scope and application of Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA). This legislation applies to Bombardier (Canadair) CL-600 (Challenger) Series aeroplanes, namely the model CL-600-2B19 “Regional Jet” with serial numbers ranging from 7003 to 7480 inclusive. The directive aims to rectify unsafe conditions by mandating the replacement of cargo compartment smoke detectors. The requirement is to replace the existing smoke detectors (Part Number 473052) with new ones (Part Number 473597-19) in accordance with Bombardier Service Bulletin 601R-26-016 dated 23 March 2001 or its revision A dated 15 June 2001. Compliance with this directive must be achieved within 15 months from the effective date of 6 September 2001. The directive extends across the Commonwealth of Australia, ensuring uniform safety standards are met by relevant entities operating these aircraft within Australian jurisdiction.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, include a schedule of Airworthiness Directives (ADs) issued by the Civil Aviation Safety Authority (CASA). Section 39.1 (1) of the Civil Aviation Regulations 1998 (CAR) empowers CASA to issue such directives, and in this instance, AD/CL-600/43 pertains to Bombardier (Canadair) CL-600 (Challenger) Series Aeroplanes. This directive applies to Model CL-600-2B19 “Regional Jet” aeroplanes with serial numbers ranging from 7003 through 7480 inclusive. The requirement outlined in this AD is the replacement of cargo compartment smoke detectors, specifically those with Part Number (P/N) 473052, with new smoke detectors P/N 473597-19. This replacement must be performed in accordance with Bombardier Service Bulletin 601R-26-016 dated 23 March 2001 or its revision A dated 15 June 2001. The AD imposes several obligations on the entities it governs. Primarily, it mandates that the specified replacement of the cargo compartment smoke detectors be conducted within 15 months from the effective date of the directive, which is 6 September 2001. This directive is issued to ensure that the aircraft remain airworthy by addressing the identified issue of false “CARGO SMOKE” warnings due to the susceptibility of the original smoke detectors to dirt, condensation, and electromagnetic interference. The false warnings can compromise the effectiveness of the Engine Indication and Crew Alerting System (EICAS), thereby posing a potential risk to flight safety. Failure to comply with this Airworthiness Directive may result in various consequences. The primary concern is that the continued operation of the aircraft without the mandated smoke detector replacement could lead to the aforementioned false warnings, undermining the safety and reliability of the EICAS. This could potentially result in regulatory action by CASA, as non-compliance with ADs is a breach of the Civil Aviation Regulations 1998. The consequences of such breaches can include fines, operational restrictions, or even the grounding of the affected aircraft until compliance is achieved. The exact penalties and consequences would be determined by CASA in accordance with the regulatory framework and the severity of the non-compliance.
