CASA 496/08 - Direction - Cessna 441 Conquest

Overview

The Civil Aviation Safety Regulations 1998 (CASR 1998) were enacted to address safety concerns in the operation of civil aircraft and to ensure the safety regulation of air navigation within Australia. The problem this legislation was introduced to address was the structural limitations of the Cessna 441 Conquest aircraft, which posed a safety risk after accumulating 22,500 flight hours. In response to a Supplemental Inspection Document issued by the Cessna Aircraft Corporation, the Australian Civil Aviation Safety Authority (CASA) issued a direction under subregulation 11.245 of the CASR 1998 to immediately ground certain Cessna 441 Conquest aircraft in the interests of the safety of air navigation. This direction applies to aircraft with 22,500 or more hours of time-in-service, whether Australian or foreign-registered, operating within Australian territory. The direction mandates that these aircraft cannot be flown unless the Director of CASA approves the flight in writing, considering it safe. This measure is temporary and will be in effect for one year, during which CASA will consult with relevant parties to determine the safest future course of action for these aircraft. The direction is subject to tabling and disallowance in Parliament under the Legislative Instruments Act 2003 (LIA).

Scope and Application

The Civil Aviation Safety Regulations 1998, as amended, apply to all civil air operations within Australian territory and to the operation of Australian aircraft outside Australian territory, in line with the Civil Aviation Act 1988. Under these regulations, the Civil Aviation Safety Authority (CASA) has the authority to issue safety directions concerning aircraft, which are enforceable measures aimed at ensuring the safe navigation and operation of aircraft. Specifically, CASA may issue such directions under subregulation 11.245(1) of the Civil Aviation Safety Regulations 1998, provided they are reasonably necessary for safety, do not conflict with the Act, and serve CASA's functions. The scope of these directions extends to any matter affecting the safe navigation, operation, or maintenance of aircraft, and they are limited in duration by regulation 11.250, which stipulates that a direction cannot be in force for longer than one year. This particular direction pertains to the Cessna 441 Conquest aircraft that have accumulated 22,500 flight hours or more, mandating their grounding unless CASA grants written approval for specific flights. The direction applies to all operators and pilots of affected aircraft, whether they are Australian or foreign registered, and is in effect from 19 September 2008 until 18 September 2009.

Key Provisions

The Civil Aviation Safety Regulations 1998 (CASR 1998) under the Civil Aviation Act 1988 (the Act) allow the Civil Aviation Safety Authority (CASA) to issue a direction regarding any matter that affects the safe navigation, operation, or maintenance of aircraft (subsection 9.245(1) of CASR 1998). Such a direction can only be issued if it is reasonably necessary for the safety of air navigation, is not inconsistent with the Act, and aligns with CASA's functions (subsection 9.245(2) of CASR 1998). The authority to issue these directions is vested solely in the Director of CASA (subsection 9.260(2) of CASR 1998). Furthermore, any direction issued under this authority cannot remain in force for more than one year (regulation 9.250 of CASR 1998). The direction ceases to be in effect on the day specified within it or, if no day is specified, one year after it commences. Under this legislative framework, CASA has issued a direction to each operator and pilot of a Cessna 441 Conquest aircraft that has accumulated 22,500 flight hours or more. This direction prohibits the aircraft from being flown unless the Director of CASA has given written approval, which includes details of the flight such as time, route, purpose, and risk mitigators (subsection 9.245 of CASR 1998). This directive applies to both Australian-registered aircraft and foreign-registered aircraft within Australian territory. The authority to issue such a direction is grounded in subsection 98(5A) of the Act, and it is considered a legislative instrument under the Legislative Instruments Act 2003 (LIA), subject to the provisions for tabling and disallowance in Parliament (subsection 98(5B) of the Act). The obligations imposed by this direction are significant for the operators and pilots of the affected Cessna 441 Conquest aircraft. Operators must ensure that their aircraft do not take flight unless they have received written approval from the Director of CASA. This approval must detail the specifics of the intended flight, including the time, route, purpose, and any measures to mitigate risks associated with the flight. Failure to comply with this direction can have serious ramifications. The consequences of non-compliance may include civil or criminal penalties, although the specific penalties are not outlined in the text. The overarching objective is to ensure that the safety of air navigation is maintained, given the structural limitations of these aircraft when they reach the specified flight hour threshold. In summary, CASA has issued a temporary direction under the Civil Aviation Safety Regulations 1998 to ground all Cessna 441 Conquest aircraft that have reached or exceeded 22,500 flight hours. This measure is aimed at ensuring the safety of air navigation in light of the manufacturer's recommendation that the aircraft should be retired due to structural limitations. The direction mandates that these aircraft cannot be flown unless the Director of CASA has provided written approval. This directive is in effect from 19 September 2008 until 18 September 2009 and is subject to parliamentary oversight under the Legislative Instruments Act 2003.
