AD/BEECH 90/43 - Seat Locking Pins - Replacement

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, represent a comprehensive framework for ensuring the safety and efficiency of civil aviation within the country. This legislative instrument addresses critical safety concerns by imposing stringent requirements on aircraft operation, maintenance, and airworthiness. The Regulations were introduced to mitigate risks associated with aviation incidents and accidents, aiming to protect the lives of passengers and crew, as well as the general public on the ground. One specific directive within these regulations is the Airworthiness Directive concerning Beechcraft 90 and 65-90 (King Air) Series Aeroplanes, aiming to ensure that these aircraft meet specified safety standards by mandating the replacement of seat locking pins. This directive, identified as AD/BEECH 90/43, was established to address identified safety issues related to the locking mechanism of seats on these aircraft models, ensuring compliance within a specified timeframe to maintain airworthiness and safety standards.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to airworthiness directives issued by the Civil Aviation Safety Authority (CASA) and includes the replacement of seat locking pins in certain Beechcraft 90 and 65-90 (King Air) Series aeroplanes. This legislation applies to aircraft with specific serial numbers, namely Model C90 with serial numbers LJ-654, LJ-674 to LJ-676, and Model E90 with serial numbers LW-134, LW-157 to LW-163. The directive mandates compliance within 100 hours of time in service following 31 May 1976. The geographic and jurisdictional reach of this regulation is national, applying across all of Australia, as it falls under the Commonwealth's authority. The directive is referenced through documents such as Beechcraft Service Instruction No. 0789-314 or FAA AD 76-04-02, indicating that CASA can extend or align its directives with those of other jurisdictions, such as the Federal Aviation Administration (FAA). There are no stated exclusions or exemptions in the provided text, and the directive is specific to the identified models and serial numbers, ensuring targeted application.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, include detailed provisions for the airworthiness directives concerning the Beechcraft 90 and 65-90 (King Air) series aeroplanes. Section AD/BEECH 90/43 mandates the replacement of seat locking pins on specific models and serial numbers of the King Air aircraft (paragraph 1). This directive applies to Model C90 with serial numbers (S/Nos) LJ-654, LJ-674 to LJ-676, and Model E90 with S/Nos LW-134, LW-157 to LW-163 (paragraph 2). Compliance is to be achieved by following either Beechcraft Service Instruction (SI) No. 0789-314 or Federal Aviation Administration (FAA) AD 76-04-02 (paragraph 3). The requirement must be fulfilled within 100 hours of time in service after 31 May 1976 (paragraph 4). The Civil Aviation Regulations 1998 impose specific obligations on the operators and owners of the affected Beechcraft 90 and 65-90 series aeroplanes. Owners and operators must ensure that the seat locking pins are replaced as per the stipulated documents and timeframe (section AD/BEECH 90/43, paragraph 3). They are responsible for verifying that the aircraft meets the airworthiness standards set out in the directive before continuing any flight operations (section AD/BEECH 90/43, paragraph 4). Any modifications or replacements must be documented and logged as per regulatory requirements to maintain the aircraft’s airworthiness certification. Failure to comply with the airworthiness directive outlined in the Civil Aviation Regulations 1998 can result in severe civil or criminal penalties. The non-compliance with airworthiness directives can be considered a breach of the regulations, leading to enforcement actions by the Civil Aviation Safety Authority (CASA). Depending on the severity and circumstances of the breach, penalties may include fines, suspension or revocation of the aircraft's airworthiness certificate, and potential criminal charges against the operators or owners. The exact penalties are determined by CASA and can vary based on the specific breach and its impact on aviation safety.
