AD/BEECH 200/20 Amdt 3 - Cabin Door Pins - Fatigue Life Limitation

Overview

The Civil Aviation Regulations 1998, as amended through the legislative instrument F2006B03678, address specific safety concerns related to the Beechcraft 200 (Super King Air) series aeroplanes. This legislation, enacted by the Australian Parliament, aims to ensure the continued airworthiness and safety of these aircraft by implementing directives that are essential for the operational integrity of the aircraft. The policy objective of these regulations is to maintain a high standard of safety within Australia's civil aviation sector, ensuring that aircraft meet necessary safety criteria through detailed directives and amendments. The specific legislative instrument F2006B03678 amends the Airworthiness Directives for the Beechcraft 200 series aeroplanes, particularly focusing on the cabin door pins. This amendment was introduced to address potential safety issues related to the fatigue life of the cabin door pins, requiring their retirement upon reaching 4500 pressurised flight cycles. By setting these compliance requirements, the Civil Aviation Safety Authority aims to mitigate risks associated with mechanical failure, thereby enhancing overall aviation safety.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically Part 39 - 105 of the Civil Aviation Regulations 1998, applies to all Beechcraft 200 (Super King Air) series aeroplanes not equipped with a cargo door. This regulation mandates the retirement of the cabin door upper locking pins P/N 50-430177-3 and lower locking pins P/N 50-430018-9 from service upon or prior to these pins achieving 4500 pressurised flight cycles to ensure safety and compliance. The regulation extends to all operators, owners, and maintenance personnel of the specified aircraft within the Commonwealth of Australia, ensuring that these safety standards are uniformly enforced across the national airspace. The scope of the directive is clearly defined, with no stated exclusions or exemptions, thus mandating that all relevant parties adhere strictly to the compliance requirements outlined. The application of this directive may be further specified or extended through subordinate instruments issued by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105 under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, includes provisions for Beechcraft 200 (Super King Air) Series Aeroplanes, focusing on the AD/BEECH 200/20 Amendment 3 concerning cabin door pins (section 4/85). This amendment targets all model 200 series aircraft not equipped with a cargo door. The primary requirement of this directive is the mandatory retirement of specific cabin door upper locking pins (P/N 50-430177-3) and lower locking pins (P/N 50-430018-9) from service. This requirement is triggered upon or prior to the locking pins reaching 4500 pressurised flight cycles, underscoring the importance of adhering to the specified fatigue life limitation. To ensure compliance with these provisions, operators of the affected Beechcraft 200 series aeroplanes must rigorously monitor the pressurised flight cycles of the specified cabin door pins. Operators are obligated to retire the specified pins before or at the 4500 flight cycle threshold, ensuring that the aircraft remain in a safe and airworthy condition. This involves regular inspections and accurate record-keeping of flight cycles for the identified parts. Furthermore, operators must ensure that replacement pins are installed in accordance with the manufacturer's guidelines and any additional CASA requirements, thereby maintaining the structural integrity and safety of the aircraft. The implications of non-compliance with these directives can be severe. Operators who fail to adhere to the specified fatigue life limitation and retire the cabin door pins as required may face significant penalties. Under the Civil Aviation Regulations 1998, non-compliance can result in enforcement actions by CASA. The potential consequences may include fines, operational restrictions, or even the grounding of the aircraft until compliance is achieved. These measures are in place to ensure that all aircraft operating within Australia's airspace meet the stringent safety standards set forth by CASA. The exact penalties can vary, but the seriousness of the breach and its potential impact on safety will be key considerations in determining the appropriate response.
