AD/AIRCON/2 - Godfrey Cabin Supercharger Type 15 - Modification

Overview

The Civil Aviation Regulations 1998, as amended, provide the legislative framework for ensuring the safety and efficiency of civil aviation in Australia. One such amendment is the inclusion of Airworthiness Directives under Part 39, specifically concerning airconditioning equipment, such as the Godfrey Cabin Supercharger Type 15. Enacted by the Australian Government, this legislation aims to address safety concerns related to the secure attachment of components within the cabin superchargers. The directive mandates modifications to ensure a positive locking mechanism for the nuts to studs and studs to supercharger casing, with compliance required immediately. This amendment is intended to mitigate potential safety risks associated with the loosening of components during flight, thereby upholding the stringent safety standards set forth by the Civil Aviation Safety Authority.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39, applies to all persons and entities involved in the operation and maintenance of aircraft within Australia, including airlines, aircraft manufacturers, maintenance organisations, and pilots. This legislation sets forth comprehensive safety standards, including airworthiness directives, to ensure the safe operation of aircraft. The geographic reach of these regulations is national, governing all civil aviation activities within Australian territory, including its states and territories. The specific Airworthiness Directive AD/AIRCON/2 concerning the Godfrey Cabin Supercharger Type 15 mandates a modification to the attachment of the oil metering unit and the bearing cover plate to ensure positive locking of nuts to studs and studs to the supercharger casing. Compliance with this directive is mandatory and must be implemented forthwith. The Act allows for the use of lockwiring of drilled studs and castellated nuts, or plain washers, spring washers, and lockwired plain nuts as acceptable means of compliance. The regulations may be extended or further clarified through subordinate instruments, ensuring that safety standards are consistently applied and updated as necessary.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 – 107, addresses the airworthiness directives for various aircraft components, with AD/AIRCON/2 concerning the Godfrey Cabin Supercharger Type 15. This directive (section 39-107) mandates that the attachment of the oil metering unit and the bearing cover plate to the cabin supercharger must be modified to ensure a positive locking mechanism. This can be achieved by lockwiring the drilled studs and castellated nuts, or by using plain washers, spring washers, and lockwired plain nuts. The directive requires these modifications to be completed forthwith (section 39-107). The obligations imposed by this directive are clear and specific. Operators and maintainers of aircraft equipped with the Godfrey Cabin Supercharger Type 15 must ensure that the modifications outlined in the directive are implemented without delay. This includes verifying that the nuts to studs and studs to supercharger casing are securely locked, utilising the acceptable methods mentioned. Compliance with this directive is mandatory, and it is the responsibility of the aircraft operator to ensure that these modifications are made before continuing operations. Failure to comply with the requirements of AD/AIRCON/2 may result in severe consequences. The Civil Aviation Safety Authority (CASA) has the authority to enforce compliance, and non-compliance can lead to significant penalties. While the specific penalties are not detailed in this directive, general aviation regulations often include fines and potential grounding of the aircraft until compliance is achieved. Furthermore, ongoing non-compliance could result in more severe penalties, including potential criminal charges if the breach leads to safety incidents or accidents. In summary, AD/AIRCON/2 requires immediate modifications to the Godfrey Cabin Supercharger Type 15 to ensure secure locking of the oil metering unit and bearing cover plate. Operators must adhere to these requirements to maintain airworthiness standards. Non-compliance can result in substantial penalties and enforcement actions by CASA, highlighting the critical importance of timely and accurate implementation of these modifications.
