Overview
The Civil Aviation Regulations 1998, as amended by the legislative instrument F2006B04729, introduce specific Airworthiness Directives aimed at enhancing the safety standards of civil aviation within Australia. This legislative instrument was enacted by the Commonwealth of Australia to address specific safety concerns related to Pilatus Britten-Norman BN-2 Series Aeroplanes, particularly focusing on engine oil return pipes. The policy objective of these regulations is to ensure that all relevant modifications are implemented to mitigate potential risks, thereby maintaining a high standard of airworthiness and safeguarding the lives of passengers and crew. The directive applies to all models of the BN-2 Series, mandating compliance within 100 hours of time in service following the publication date of 26 February 1971.
Scope and Application
The Civil Aviation Regulations 1998, as amended, apply to all persons and entities involved with the operation, maintenance, and modification of Pilatus Britten-Norman BN-2 series aeroplanes within the Commonwealth of Australia. Specifically, the regulations pertain to the modification of engine oil return pipes as outlined in Airworthiness Directive AD/BN-2/18. This directive applies uniformly across all models of the BN-2 series aeroplanes and mandates compliance within 100 hours of time in service following 26 February 1971. The Civil Aviation Safety Authority, under the authority of the Commonwealth, oversees the implementation and enforcement of these regulations, ensuring adherence to the specified technical standards for airworthiness. The scope of these regulations is further extended and clarified through subordinate instruments and official documents such as the Britten Norman Service Bulletin BN-2/SB.40 Issue 2, which provides detailed guidance on the required modifications and compliance procedures.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39, includes a Schedule of Airworthiness Directives (ADs) that pertain to the Pilatus Britten-Norman BN-2 Series Aeroplanes. One such directive is AD/BN-2/18, which mandates the modification of engine oil return pipes. This directive applies to all models of the BN-2 series aeroplanes (s. 39-105). The specific document referenced for compliance is the Britten Norman Service Bulletin BN-2/SB.40, Issue 2, which outlines the required modifications and the procedures to follow. Compliance with this directive must be achieved within 100 hours of time in service after the directive was issued on 26 February 1971.
The obligations imposed by AD/BN-2/18 require operators and owners of BN-2 series aeroplanes to ensure that the engine oil return pipes are modified as specified in the referenced service bulletin. This includes conducting the necessary inspections, making any required modifications, and maintaining records of compliance to demonstrate adherence to the directive. The modifications are intended to address potential safety issues related to the engine oil return pipes, thus ensuring the continued airworthiness of the aircraft.
Failure to comply with AD/BN-2/18 can lead to significant consequences. The Civil Aviation Safety Authority (CASA) may take enforcement action against operators who do not comply with the directive. Potential penalties include fines, enforcement notices, or even the grounding of non-compliant aircraft. Operators may also face liability for accidents or incidents that arise from non-compliance with the airworthiness directive. The exact penalties and consequences are determined by CASA based on the severity of the breach and the impact on aviation safety.
