AD/BEECH 55/20 Amdt 1 - Plastic Control Wheel

Overview

The Civil Aviation Regulations 1998, as amended, include specific directives under PART 39 - 105, addressing the safety and airworthiness of aircraft. One such directive, AD/BEECH 55/20 Amendment 1, pertains to Beechcraft 55, 58, and 95-55 (Baron) series aeroplanes. Enacted by the Civil Aviation Safety Authority, this regulation was introduced to address a critical safety issue associated with the use of non-reinforced plastic control wheels in these aircraft models. The problem it aimed to resolve involves the potential for cracking in plastic control wheels, which could compromise flight safety. The policy objective behind this directive is to ensure the ongoing airworthiness of these aircraft by mandating regular inspections and necessary replacements of control wheels to prevent any risk of in-flight failure. The directive specifies that all models fitted with non-reinforced plastic control wheels must undergo a visual inspection for cracks at intervals not exceeding 100 hours of time in service after 31 December 1970. Any control wheels found to have cracks must be replaced with a serviceable item, preferably of the metal reinforced type, before further flight. This regulation underscores the commitment to maintaining stringent safety standards within the aviation sector by ensuring that any potential risks are identified and mitigated proactively.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, govern the safety directives for aviation in Australia, including the issuance of Airworthiness Directives (ADs) by the Civil Aviation Safety Authority (CASA). One such directive, AD/BEECH 55/20 Amendment 1, pertains to the Beechcraft 55, 58, and 95-55 (Baron) series aeroplanes equipped with non-reinforced plastic control wheels. This regulation applies to all operators of these specific models and mandates a visual inspection of the plastic control wheels to check for any cracking. Any control wheels found to have cracks must be replaced with a serviceable item, preferably of the metal-reinforced type, before the aircraft can be flown again. Compliance with this directive is required at intervals not exceeding 100 hours of time in service after 31 December 1970. The directive's scope is limited to the specified aircraft models and their respective control wheels, ensuring that the safety and airworthiness standards are maintained across the relevant fleet.

Key Provisions

The Civil Aviation Regulations 1998, under PART 39 - 105, contain specific airworthiness directives that apply to certain aircraft models, including the Beechcraft 55, 58 and 95-55 (Baron) Series Aeroplanes. A notable directive, AD/BEECH 55/20 Amendment 1, pertains to the plastic control wheel (Section 12/70). This directive applies to all models of the specified Beechcraft series that are fitted with non-reinforced plastic control wheels. The primary requirement of this directive is that all such control wheels must be visually inspected for cracking. If any cracks are found, the affected control wheel must be replaced with a serviceable item before the aircraft is flown again. It is also recommended that the replacement should be of the metal reinforced type to avoid similar issues in the future. The obligations imposed by this directive are straightforward but critical for ensuring the safety of the aircraft. Operators of the affected Beechcraft models must ensure that all plastic control wheels are regularly inspected at intervals not exceeding 100 hours of time in service after 31 December 1970. This ensures that any potential issues are identified and rectified promptly, thereby maintaining the airworthiness of the aircraft. The directive underscores the importance of timely and thorough inspections to prevent any potential failure that could compromise the control of the aircraft. Failure to comply with this airworthiness directive could have serious consequences. The Civil Aviation Regulations 1998 do not specify particular offences or penalties for non-compliance with AD/BEECH 55/20 Amendment 1 within the legislative instrument provided. However, non-compliance with airworthiness directives generally can result in significant civil or criminal penalties. Civil penalties could include fines or other monetary penalties, while criminal penalties could involve imprisonment, reflecting the serious nature of ensuring aircraft safety. Operators must adhere strictly to these requirements to avoid potential legal repercussions and to maintain the highest safety standards in civil aviation.
