AD/BEECH 90/5 Amdt 1 - Landing Gear Chain and Torque Shaft - Inspection

Overview

The Civil Aviation Regulations 1998, specifically within Part 39 - 105 of the Civil Aviation Safety Authority Schedule of Airworthiness Directives, address the safety of aircraft through the issuance of directives that ensure compliance with safety standards. One such directive, AD/BEECH 90/5 Amendment 1, pertains to the Beechcraft 90 and 65-90 (King Air) Series Aeroplanes. This directive was enacted to address the need for regular inspection of the landing gear chain and torque shaft, ensuring that these critical components are maintained in a safe and operational condition. The directive applies to a specific range of serial numbers, LJ-114 to LJ-221, and mandates compliance immediately as per Beechcraft Service Bulletin 67-1. The objective of this legislation is to maintain the highest safety standards in civil aviation, thereby protecting the lives of passengers and crew and ensuring the integrity of the aviation industry. The directive is enacted by the Civil Aviation Safety Authority, acting on behalf of the Commonwealth of Australia, to uphold stringent safety measures.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39 - 105, specifically applies to the Beechcraft 90 and 65-90 (King Air) Series Aeroplanes, with the focus being on model 65-A90 aircraft serial numbers LJ-114 to LJ-221. This legislation mandates immediate compliance with AD/BEECH 90/5 Amendment 1, which concerns the inspection of the landing gear chain and torque shaft. The regulation applies directly to these specified serial numbers, ensuring the maintenance and safety standards of these aircraft are upheld through rigorous inspection protocols. The geographic and jurisdictional reach of this regulation is national, applying across the Commonwealth of Australia, and it is overseen by the Civil Aviation Safety Authority. This regulation does not explicitly state any exclusions, exemptions, or thresholds within the provided text, but it does set a mandatory compliance timeline. Furthermore, while the primary legislation is detailed here, it may be supplemented or further clarified by subordinate instruments issued by the Civil Aviation Safety Authority, ensuring the applicability and enforcement of these safety directives are consistent and comprehensive.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, which applies to various types of aircraft. Within this schedule, AD/BEECH 90/5 Amendment 1 pertains to the inspection of the landing gear chain and torque shaft of Beechcraft 90 and 65-90 (King Air) series aeroplanes. This directive applies to Model 65-A90 serial numbers ranging from LJ-114 to LJ-221. The directive references document Beechcraft SB 67-1 and requires compliance immediately, denoted as "forthwith." The key provisions of AD/BEECH 90/5 Amendment 1 impose specific obligations on the operators of the affected Beechcraft aeroplanes. Primarily, these operators must ensure that the landing gear chain and torque shaft are inspected in accordance with the guidelines provided in Beechcraft SB 67-1. This directive underscores the importance of maintaining these critical components to ensure the continued airworthiness and safety of the aircraft. Operators must take immediate action to comply with these requirements to avoid any potential safety risks. Failure to comply with AD/BEECH 90/5 Amendment 1 can lead to significant consequences. Under the Civil Aviation Act 1988, non-compliance with an airworthiness directive can result in civil penalties. These penalties may include fines up to the maximum allowable by law, which can be substantial for non-compliance with safety directives. Additionally, continued operation of an aircraft that does not meet the specified airworthiness requirements can lead to enforcement actions by CASA, including the potential grounding of the aircraft until the required inspections and repairs are completed. In summary, AD/BEECH 90/5 Amendment 1 is a critical directive that mandates the immediate inspection of the landing gear chain and torque shaft of specific Beechcraft 90 and 65-90 series aeroplanes. Operators must adhere to the requirements set forth in Beechcraft SB 67-1 to ensure compliance. The consequences of failing to comply with this directive are severe, encompassing civil penalties and the potential for enforcement actions by CASA. It is imperative that operators take these directives seriously to maintain the highest standards of aviation safety.
