Overview

The Civil Aviation Regulations 1998, as amended by the Airworthiness Directive (AD/AMD 50/21) issued by the Civil Aviation Safety Authority (CASA) on 16 January 2001, address the gap in emergency procedures for rapid cabin depressurisation in Mystère Falcon 50 and Mystère Falcon 900 aeroplanes. This legislation was enacted to ensure the safety of passengers and crew in the event of a rapid cabin depressurisation incident. The directive requires the amendment of the Aircraft Flight Manual (AFM) to include specific emergency procedures and mandates that these changes be implemented by 22 January 2001. The policy objective is to mitigate safety risks associated with such incidents by providing clear and actionable instructions to the flight crew.

Scope and Application

The Airworthiness Directive (AD) under the Civil Aviation Regulations 1998 applies to all Mystère Falcon 50 and Mystère Falcon 900 aeroplanes. It is issued by the Civil Aviation Safety Authority (CASA) to address the identified unsafe condition related to the lack of emergency procedures for rapid cabin depressurisation in the Aircraft Flight Manuals (AFMs). The directive requires the amendment of the AFMs by incorporating interim emergency procedures for rapid cabin depressurisation, which may be removed once specific AFM changes are incorporated. The directive became effective on 19 January 2001, with compliance required by 22 January 2001 for the interim procedures, and at the time when the specific AFM changes are incorporated. The AD is part of the Civil Aviation Regulations 1998 and has a national jurisdictional reach, applying across the Commonwealth of Australia.

Key Provisions

The Civil Aviation Regulations 1998 (CAR 1998) outline several key provisions, particularly under Part 39 - 105, which pertains to the issuance of Airworthiness Directives (AD) by the Civil Aviation Safety Authority (CASA). Section 39.1 (1) empowers CASA to issue such directives when necessary to correct unsafe conditions on aircraft or aeronautical products. In the case of the Mystère Falcon 50 and 900 aeroplanes, a specific AD (AD/AMD 50/21) was issued to address rapid cabin depressurisation emergencies (Section 39.1 (1)). This AD is applicable to all Mystère Falcon 50 and 900 aeroplanes and became effective on 19 January 2001. The primary requirement of this AD (Section 39.1 (1)) is to amend the Aircraft Flight Manual (AFM) by inserting new emergency procedures for rapid cabin depressurisation. These procedures include donning crew oxygen masks, setting the microphone selector to "MASK", ensuring the "FASTEN BELTS" and "no smoking" lights are on, overriding the oxygen controller and donning passenger masks, and initiating an emergency descent. The amendment may be achieved by inserting a copy of the directive into the AFM. Subsequently, when specific AFM amendments are incorporated, the interim procedures may be removed (Section 39.1 (1)). Compliance with these requirements must be met by 22 January 2001 for the initial amendment and upon the incorporation of the specified AFM changes for the subsequent removal of the interim procedures. The AD imposes obligations on the operators of Mystère Falcon 50 and 900 aeroplanes to ensure that their AFMs are updated to include the specified emergency procedures by the compliance date. Operators must follow the instructions provided in the directive to correctly amend their AFMs and ensure that all crew members are aware of the new procedures. Once the specified AFM changes are incorporated, operators must also remove the interim procedures as directed. Failure to comply with these obligations could result in safety risks during rapid cabin depressurisation events. Failure to comply with the requirements of the AD may lead to enforcement actions. Although specific offences and penalties are not detailed in the AD itself, non-compliance with ADs under CAR 1998 could result in civil penalties, including fines, as well as potential criminal penalties if the non-compliance leads to safety incidents. The exact penalties would be determined based on the specific circumstances and the severity of the non-compliance.
