Overview
The Civil Aviation Regulations 1998, as amended by the legislative instrument F2006B04278, introduce specific airworthiness directives aimed at ensuring the safety of civil aviation operations. This particular directive, AD/BEECH 90/95, was enacted to address the issue of debris entering the landing gear hand pump system of Beechcraft 90 and 65-90 (King Air) Series Aeroplanes, which could compromise the functionality of the landing gear. The directive applies to all Beechcraft C90A model airplanes with specific serial numbers. The requirement is to install a filter element in the landing gear hand pump suction line to prevent debris from causing operational failures. This modification is in accordance with Raytheon Mandatory Service Bulletin SB 32-3073 Revision 1 dated July 1998. Compliance with this directive must be achieved within 200 hours of time in service from its effective date of 9 September 1999. The objective of this legislative instrument is to enhance the safety of civil aviation by mitigating risks associated with landing gear system failures due to debris.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the safety standards for airworthiness directives, including the AD/BEECH 90/95 concerning Beechcraft 90 and 65-90 (King Air) series aeroplanes. This regulation applies to all Beechcraft C90A model airplanes with serial numbers ranging from LJ1063 to LJ-1482, mandating the installation of a filter element in the landing gear hand pump suction line as per Raytheon Mandatory Service Bulletin SB 32-3073 Revision 1 dated July 1998. This directive aims to prevent debris from entering the landing gear hand pump system, which could otherwise compromise the successful operation of the system. Compliance with this directive is required within 200 hours' time in service (TIS) from the effective date of the directive, which is 9 September 1999. The directive is linked to the US FAA AD 99-09-10 Amdt 39-11143 dated 26 April 1999, indicating a collaborative approach to aviation safety standards across jurisdictions.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39, includes detailed airworthiness directives for various aircraft models, among them the Beechcraft 90 and 65-90 (King Air) series aeroplanes. In relation to these aircraft, Airworthiness Directive (AD) AD/BEECH 90/95 (section 105) mandates a particular modification to the landing gear hand pump. This directive applies to all Beechcraft C90A model airplanes with serial numbers ranging from LJ1063 to LJ-1482. According to the directive, it is mandatory to install a filter element in the landing gear hand pump suction line as outlined in Raytheon Mandatory Service Bulletin SB 32-3073 Revision 1 dated July 1998. This requirement is closely aligned with the US Federal Aviation Administration’s AD 99-09-10 Amdt 39-11143 dated 26 April 1999.
The installation of the filter element must be completed within 200 hours of time in service (TIS) from the effective date of the directive, which is 9 September 1999. The directive's purpose is to address the issue of debris entering the landing gear hand pump system, which can compromise the system's functionality. By implementing this modification, the directive aims to prevent debris from causing further complications within the system.
Compliance with this airworthiness directive is mandatory for all operators of the specified Beechcraft C90A model airplanes. Failure to comply with the requirements outlined in AD/BEECH 90/95 could result in significant safety risks. Operators must ensure that the filter element is correctly installed within the specified timeframe to maintain the airworthiness of the aircraft and to adhere to regulatory standards. Non-compliance could potentially lead to operational disruptions, increased safety risks, and possibly severe regulatory consequences.
The legislation imposes strict obligations on aircraft operators to adhere to airworthiness directives such as AD/BEECH 90/95. This includes not only the installation of the required filter element but also ensuring that all modifications are carried out in accordance with the specified bulletin and within the prescribed timeframe. Operators must maintain thorough records of compliance to demonstrate adherence to the regulatory requirements. Additionally, the directive necessitates that operators stay informed about updates and modifications to airworthiness directives, ensuring ongoing compliance with safety standards. Failure to meet these obligations could result in enforcement actions, including potential penalties and sanctions imposed by the Civil Aviation Safety Authority.
