Overview
The Civil Aviation Regulations 1998 (Cth), specifically Part 39 - 105, was enacted to ensure the safety and efficiency of civil aviation within Australia. One of the key amendments within this part is the Airworthiness Directive (AD) concerning the Beechcraft 77 (Skipper) Series Aeroplanes, identified as AD/BEECH 77/7 Amendment 1. This directive was introduced to address specific safety concerns related to the shoulder harness attach bracket of certain model 77 aircraft, ensuring compliance with safety standards to prevent potential failures due to insufficient rivets and fastener edge distance. The AD mandates corrective actions as outlined in Beechcraft Service Information (SI) No. 1173, Revision 1, with compliance required within 100 hours’ time in service after 30 September 1981. The objective of this legislation is to mitigate safety risks and maintain the airworthiness of the affected aircraft, thereby protecting passengers and crew.
This legislative instrument is part of the broader framework established by the Australian Government under the Civil Aviation Act 1988 (Cth) and is administered by the Civil Aviation Safety Authority (CASA). The policy objective underpinning these regulations is to ensure that all civil aviation activities within Australia adhere to stringent safety standards, thereby safeguarding the public and maintaining the integrity of the aviation industry.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to the Beechcraft 77 (Skipper) Series Aeroplanes as outlined in the Airworthiness Directive AD/BEECH 77/7 Amendment 1 concerning the Shoulder Harness Attach Bracket. This legislation mandates specific action for all model 77 aircraft with serial numbers ranging from WA-3 to WA-235, WA-237, WA-238, WA-240 to WA-254, WA-256, WA-258, WA-261 to WA-264, WA-266, WA-267, and WA-269. The requirement mandates compliance with Beechcraft Service Instruction No. 1173, Revision 1, as referenced by FAA AD 81-09-05 Amendment 39-4101. This directive ensures that these aircraft are maintained to address issues related to insufficient rivets and fastener edge distance in the shoulder harness attach bracket. Compliance must be achieved within 100 hours’ time in service after 30 September 1981. The directive extends to include additional serial numbers identified as potentially affected, thus broadening the scope of the mandatory action to enhance airworthiness and safety standards.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses airworthiness directives for particular aircraft models, including the Beechcraft 77 (Skipper) Series Aeroplanes. In this context, the regulation AD/BEECH 77/7 Amendment 1 (paragraph 9/81) pertains to the shoulder harness attach bracket of the specified aircraft models. The applicability of this directive (section 9/81) is limited to certain serial numbers of the Beechcraft 77 (Skipper) Series Aeroplanes, namely WA-3 to WA-235, WA-237, WA-238, WA-240 to WA-254, WA-256, WA-258, WA-261 to WA-264, WA-266, WA-267, and WA-269. The primary requirement (section 9/81) is that action must be taken in accordance with Beechcraft Service Instruction No. 1173, Revision 1, and that this aligns with the Federal Aviation Administration Airworthiness Directive AD 81-09-05 Amendment 39-4101.
The obligations imposed by this regulation (section 9/81) necessitate that aircraft operators ensure compliance with the specified requirements within 100 hours of time in service after 30 September 1981. This means that operators must perform the necessary actions to address the shoulder harness attach bracket issues, specifically those related to insufficient rivets and fastener edge distance, within this timeframe. This requirement ensures that the aircraft meet the safety standards set forth by the Civil Aviation Safety Authority (CASA).
Failure to comply with the airworthiness directive (section 9/81) can lead to significant consequences. While the specific penalties or consequences are not detailed in the provided text, it is reasonable to infer that non-compliance with CASA regulations could result in penalties under the Civil Aviation Act 1988 or other relevant legislation. Such penalties could include fines or other civil or criminal consequences, which might be significant depending on the severity and impact of the non-compliance on aviation safety.
