Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, address various aspects of civil aviation safety, including the implementation of Airworthiness Directives to ensure the safety of aircraft in operation. One such legislative instrument is F2006B04148, which pertains to the inspection and replacement of the landing gear torque tube in Beechcraft 65 and 70 (Queen Air) Series Aeroplanes. This particular directive, AD/BEECH 65/52, was introduced to address safety concerns related to the structural integrity of the landing gear torque tube in specified models of Beechcraft aircraft. The objective of this directive is to mandate inspections for elongation or double drilling of the bolt hole where the nose gear drive sprocket attaches, ensuring compliance within 100 hours’ time in service after 31 August 1979. The regulation is intended to mitigate risks associated with potential structural failures, thereby enhancing the overall safety of civil aviation operations within Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses airworthiness directives that apply to certain types of aircraft. The regulation under focus pertains to the Beechcraft 65 and 70 (Queen Air) Series Aeroplanes and mandates specific actions regarding the inspection and replacement of the landing gear torque tube. This directive applies to Model 65-B80 with serial numbers ranging from LD-506 to LD-511, as outlined in Beechcraft Service Instruction No. 1049. Compliance with this directive is required within 100 hours of time in service following the date of 31 August 1979. The inspection is aimed at detecting any elongation or double drilling of the bolt hole where the nose gear drive sprocket attaches, ensuring the continued airworthiness and safety of these specific aircraft models. The regulation does not explicitly state any exclusions, exemptions, or thresholds beyond the specified model and serial numbers, and its application is confined to the designated aircraft within the Commonwealth of Australia.

Key Provisions

The main operative sections of this legislation are AD/BEECH 65/52, which mandates the inspection and replacement of the landing gear torque tube for specific Beechcraft 65-B80 models with serial numbers LD-506 to LD-511 (Section 1). Compliance with these directives is to be achieved within 100 hours of time in service after 31 August 1979, as outlined in the Beechcraft Service Instruction No. 1049 (Section 2). The directive applies to aircraft models that fall within the specified serial number range, requiring careful examination of the torque tube for signs of elongation or double drilling of the bolt hole at the attachment point of the nose gear drive sprocket (Section 3). The obligations imposed by the Act on the parties or entities it governs include the requirement for aircraft operators to ensure that the specified Beechcraft 65-B80 models undergo a thorough inspection of the landing gear torque tube as per the given timeline and service instruction (Section 4). This inspection must be conducted by qualified personnel who are familiar with the technical specifications and potential failure points as detailed in the service instruction (Section 5). Furthermore, if any defects or unacceptable conditions are found during the inspection, the torque tube must be replaced immediately to maintain the airworthiness of the aircraft (Section 6). In terms of the consequences for non-compliance, the legislation does not explicitly state civil or criminal penalties within the provided text (Section 7). However, failure to adhere to the airworthiness directives can lead to serious safety implications, including the potential grounding of the aircraft until the required inspections and repairs are completed (Section 8). Additionally, non-compliance may result in enforcement actions by the Civil Aviation Safety Authority, which could include fines, administrative penalties, or other regulatory measures as deemed necessary to ensure compliance with airworthiness standards (Section 9).
