COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Beechcraft 90 and 65-90 (King Air) Series Aeroplanes
AD/BEECH 90/84 Landing Gear Motor Control Circuit Breaker 11/90
Applicability: All models as listed in the Requirement Document.
Requirement: Install a circuit breaker on the landing gear motor control panel in accordance with Beechcraft Mandatory Service Bulletin 2035 Revision II.
Compliance: Prior to exceeding 100 hours’ time in service after 1 November 1990.
Background: Compliance with this AD is required to install a circuit breaker in the landing gear motor circuit which will trip and open circuit the landing gear motor circuit before the motor is damaged. Failure to comply with this AD may result in damage to the landing gear motor in a manner which could restrict operation of the manual landing gear extension system, resulting in an inability to manually lower the landing gear.
Overview
The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia and administered by the Civil Aviation Safety Authority, provide comprehensive guidelines and safety standards for civil aviation in Australia. Within this legislative framework, Part 39 specifically addresses airworthiness directives aimed at ensuring the safety and reliability of aircraft. One such directive, AD/BEECH 90/84, was introduced to address the problem of potential damage to the landing gear motor in Beechcraft 90 and 65-90 (King Air) series aeroplanes, which could compromise the operation of the manual landing gear extension system. The policy objective behind this directive is to mandate the installation of a circuit breaker on the landing gear motor control panel, in accordance with Beechcraft Mandatory Service Bulletin 2035 Revision II, to prevent damage to the motor and ensure safe landing operations. Compliance with this directive is required before the aircraft exceeds 100 hours of time in service after 1 November 1990.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the airworthiness directives concerning various aircraft, including the Beechcraft 90 and 65-90 (King Air) Series Aeroplanes. This particular regulation, AD/BEECH 90/84, mandates the installation of a circuit breaker on the landing gear motor control panel to prevent potential damage to the landing gear motor. All models of the specified aircraft are subject to this directive, and compliance must be achieved prior to the aircraft exceeding 100 hours of time in service after 1 November 1990. This requirement is essential to ensure that the landing gear motor circuit is adequately protected, preventing potential failure that could impede the manual landing gear extension system and hinder the manual lowering of the landing gear. The regulation applies across the Commonwealth of Australia, enforcing safety standards set by the Civil Aviation Safety Authority. There are no stated exclusions or exemptions within the directive, and compliance is mandatory for the specified aircraft within the given timeframe.
Key Provisions
The main operative sections of the Civil Aviation Regulations 1998, specifically Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, include section AD/BEECH 90/84. This section mandates the installation of a circuit breaker on the landing gear motor control panel for Beechcraft 90 and 65-90 (King Air) Series Aeroplanes, in accordance with Beechcraft Mandatory Service Bulletin 2035 Revision II. The requirement is to install this circuit breaker prior to the aeroplane exceeding 100 hours of time in service after 1 November 1990. This directive is designed to prevent damage to the landing gear motor, which could otherwise hinder the operation of the manual landing gear extension system, potentially leading to an inability to manually lower the landing gear.
The obligations imposed on the parties or entities governed by this Act are quite specific and critical for maintaining the safety and airworthiness of the aircraft. Owners and operators of the Beechcraft 90 and 65-90 (King Air) Series Aeroplanes must ensure that the prescribed circuit breaker is installed on the landing gear motor control panel. This must be done in compliance with the requirements specified in Beechcraft Mandatory Service Bulletin 2035 Revision II. The compliance must be achieved before the aeroplane accumulates 100 hours of time in service after 1 November 1990. Failure to adhere to these requirements could compromise the safety of the aircraft and its occupants.
Any breaches of the obligations outlined in the Civil Aviation Regulations 1998, particularly in relation to the installation of the circuit breaker as mandated by AD/BEECH 90/84, could lead to severe civil and criminal consequences. While specific penalties are not detailed within the text of the Act, non-compliance with airworthiness directives is generally subject to strict regulatory enforcement. The Civil Aviation Safety Authority (CASA) has the authority to take enforcement action against operators and owners who fail to comply with these directives. This could include fines, suspension or revocation of airworthiness certificates, and other regulatory penalties. In more severe cases, such non-compliance could result in criminal charges, leading to imprisonment and significant financial penalties.
