Overview

The Civil Aviation Regulations 1998 (CAR 1998) were enacted in 1998 to provide comprehensive regulation of civil aviation in Australia, including the establishment of airworthiness standards and safety requirements for aircraft and aeronautical products. The legislation was introduced to address the need for a unified and robust regulatory framework to ensure the safety and efficiency of civil aviation operations within Australia. This includes setting forth detailed provisions for aircraft design, maintenance, operation, and certification, aiming to mitigate risks and ensure compliance with international safety standards. The regulations are administered by the Civil Aviation Safety Authority (CASA), which acts as the delegate for the Minister for Transport and Regional Services in enforcing these provisions. The Airworthiness Directive (AD) issued under PART 39 - 105 of CAR 1998 specifically targets safety concerns related to the Bell Helicopter Textron 204 Series Helicopters, focusing on the prevention of potential failures in the main transmission spiral bevel gear. This AD, issued on 8 August 2000, mandates specific actions to be taken by operators to address identified unsafe conditions, ensuring that these helicopters remain airworthy and compliant with safety regulations. The directive was issued to prevent failures that could lead to the loss of a helicopter, reflecting CASA's commitment to maintaining high safety standards in civil aviation.

Scope and Application

This legislative instrument, part of the Civil Aviation Regulations 1998, pertains specifically to the maintenance and safety standards for Bell Helicopter Textron 204 Series helicopters. The Airworthiness Directive (AD) applies to all model 204B helicopters equipped with a specific main transmission spiral bevel gear part number 204-040-701-103, which must have less than 250 hours of time in service at the effective date of this directive, and must have been delivered as spares or in a new or overhauled transmission between 1 January 1988 and 4 April 1989, and must have the specified serial numbers. The AD mandates that the action outlined in the requirement section, which follows the technical requirements of FAA AD 89-08-05, must be taken to address a specific unsafe condition identified with the mentioned gears. Compliance with this directive is required at the specified time mentioned in the compliance section. This AD is issued under the authority of a delegate of the Civil Aviation Safety Authority, and it became effective on 10 August 2000, following its notification in the Commonwealth of Australia Gazette on 12 July 2000.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39, Section 105, establish the authority of the Civil Aviation Safety Authority (CASA) to issue Airworthiness Directives (ADs) (subregulation 39.1(1)). In the case of the Bell Helicopter Textron 204 Series Helicopters, AD/BELL 204/33 mandates specific actions to address safety concerns related to the main transmission spiral bevel gear. The AD applies to all model 204B helicopters equipped with the specified main transmission spiral bevel gear parts number 204-040-701-103, provided they have less than 250 hours of service time at the effective date of the directive, were delivered as spares or in new or overhauled transmissions between 1 January 1988 and 4 April 1989, and possess the serial numbers listed in the requirement document. The action required is in accordance with the technical specifications outlined in FAA AD 89-08-05, and compliance must be achieved within the timeframes specified in the requirement document. The directive came into effect on 10 August 2000. The Airworthiness Directive imposes specific obligations on the operators of Bell Helicopter Textron 204 Series Helicopters. Operators must ensure that the specified action is carried out on the affected aircraft or aeronautical product to maintain airworthiness. This includes verifying that the helicopter falls within the applicability criteria, and taking the necessary steps to comply with the technical requirements of FAA AD 89-08-05. Operators are responsible for documenting and maintaining records of compliance with the directive. Additionally, the directive requires operators to notify CASA of any non-compliance issues and to report any adverse findings or incidents related to the specified components. Failure to comply with the requirements of the Airworthiness Directive can result in serious consequences. The Civil Aviation Regulations 1998 do not explicitly state the penalties for non-compliance with ADs, but non-compliance can lead to enforcement actions under the Civil Aviation Act 1988. Such actions may include the imposition of fines, suspension or revocation of air operator certificates, and other regulatory penalties. In severe cases, continued operation of a non-compliant aircraft could lead to criminal charges and imprisonment. Operators are strongly advised to adhere to the directive to avoid these potential repercussions and to ensure the continued safety of their operations.
