AD/BEECH 65/17 Amdt 1 - Plastic Control Wheel - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, were established to regulate civil aviation activities within the country and ensure safety standards are met. One of the legislative instruments under these regulations, F2006B04121, addresses specific safety concerns for certain aircraft models. The policy objective of this instrument is to mitigate risks associated with the structural integrity of aircraft components, specifically targeting plastic control wheels in Beechcraft 65 and 70 (Queen Air) Series Aeroplanes. By mandating regular inspections and the replacement of cracked plastic control wheels with metal-reinforced alternatives, the instrument aims to prevent potential failures that could compromise flight safety. Compliance with these directives is crucial for operators to maintain airworthiness and adhere to stringent safety standards set forth by the Civil Aviation Safety Authority.

Scope and Application

The Civil Aviation Regulations 1998, as specified in Part 39 - 105, apply to all Beechcraft 65 and 70 (Queen Air) Series Aeroplanes that are equipped with non-reinforced plastic control wheels. The regulation mandates that these plastic control wheels must be visually inspected for any signs of cracking. Any control wheels found to have cracks must be replaced with a serviceable item before the aircraft can be flown again. It is also recommended that the replacement wheels should be of the metal-reinforced type. Compliance with these requirements is necessary at intervals not exceeding 100 hours of time in service after 31 December 1970. The regulations apply on a Commonwealth level, meaning they are applicable across the entire nation, and there are no stated exclusions or exemptions within this directive. The scope of the regulation is limited to the inspection and replacement of specific components in the specified aircraft models, and any broader applications or exceptions would need to be addressed through subordinate instruments or further regulations.

Key Provisions

The Civil Aviation Regulations 1998, specifically within Part 39 - 105 under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, include provisions for ensuring the airworthiness of Beechcraft 65 and 70 (Queen Air) series aeroplanes. The relevant section, AD/BEECH 65/17 Amendment 1, addresses the inspection and potential replacement of plastic control wheels. According to this directive (section 12/70), all models of these aircraft fitted with non-reinforced plastic control wheels are subject to the requirement of regular inspections to ensure their safety. The directive mandates that all such control wheels must be visually inspected for any signs of cracking (section 12/70). If any cracks are detected, the control wheel must be replaced with a serviceable item before any further flight can occur. It is also recommended that the replacement should be a metal-reinforced type to mitigate the risk of future failures. The obligations imposed by this regulation are clear and specific. Operators of Beechcraft 65 and 70 series aeroplanes must ensure that all non-reinforced plastic control wheels are inspected for cracks at intervals not exceeding 100 hours of time in service after 31 December 1970. This requirement ensures that the aircraft remain airworthy and compliant with safety standards set by the Civil Aviation Safety Authority. Compliance with this directive is not merely a procedural step but a critical safety measure to prevent in-flight failures that could compromise the control of the aircraft. Failure to adhere to these provisions can result in serious safety risks and legal consequences. While specific offences and penalties are not detailed in this directive, non-compliance with airworthiness directives in general can lead to enforcement actions by the Civil Aviation Safety Authority. These actions may include grounding the aircraft until compliance is achieved, fines, or other regulatory penalties. The overarching goal is to ensure that all aircraft operated under these regulations maintain the highest standards of safety, thereby protecting the lives of passengers and crew, as well as the general public.
