Overview
The Civil Aviation Regulations 1998, specifically Part 39, which was enacted by the Commonwealth of Australia, is a comprehensive set of rules governing civil aviation safety. One particular legislative instrument within this framework, F2006B04257, focuses on the airworthiness directives for the Beechcraft 90 and 65-90 (King Air) series aeroplanes. This directive was introduced to address safety concerns related to the fuel boost pumps of these aircraft models. The Civil Aviation Safety Authority, as the enacting body, aims to ensure that the aircraft meet the necessary safety standards to prevent potential hazards associated with the specified fuel boost pumps. Compliance with this directive is mandatory, with specific timelines provided for inspections, modifications, and replacements to ensure the continued airworthiness and safety of the aircraft in question.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, issued by the Civil Aviation Safety Authority (CASA), outlines the Airworthiness Directives applicable to Beechcraft 90 and 65-90 (King Air) series aeroplanes. This directive applies to any Beechcraft 90 and 65-90 aeroplanes equipped with specific Airborne fuel boost pumps, identified by particular serial number date codes and repair station nameplate dates. The directive mandates that these aeroplanes undergo an initial inspection and necessary modifications to ensure compliance with the latest Service Bulletin issued by the manufacturer, Beechcraft SB No. 2156. Compliance with this directive must be achieved within specified timeframes and before further flights or installation of the affected components, ensuring that the safety and airworthiness standards are upheld. Notably, adherence to previous versions of this directive does not suffice, necessitating a new certification for compliance with the current directive.
Key Provisions
The Civil Aviation Regulations 1998, particularly Part 39 - 105, include specific provisions for airworthiness directives concerning certain models of aircraft. One such directive, AD/BEECH 90/71 Amendment 2, applies to Beechcraft 90 and 65-90 (King Air) series aeroplanes. This directive mandates actions regarding the airborne fuel boost pumps installed on these aircraft, specifically those with particular serial number date codes and repair station nameplate dates (sections 9/86). The directive applies to King Air C90 and F90 models with specific serial numbers and any other Model 90 series aeroplanes that have installed replacement fuel boost pumps with certain date codes (section 9/86).
The directive requires operators of the affected aircraft to comply with Beechcraft Service Bulletin No. 2156. This involves an initial inspection in accordance with Step 1 and modifications as per Steps 3 and 4 of the Requirement Document (section 9/86). Furthermore, any leaking boost pumps must be replaced in line with Step 2 of the Requirement Document, and affected pumps held as spares should be inspected as per the Requirement Document (section 9/86). Compliance must occur within specific timelines: within 100 hours' time in service after 30 September 1986 or before 31 March 1987, whichever comes first, and before further flight after initial inspection and before installation in an aircraft after 30 September 1986 (section 9/86).
Operators of these aircraft must adhere to strict compliance requirements. They must ensure that the initial inspection and modifications to the fuel boost pumps are conducted within the specified timeframes. Additionally, they must verify that any leaking pumps are replaced and that spare pumps are inspected as required by the directive. Failure to comply with these obligations may result in the aircraft being deemed non-airworthy, leading to potential grounding and legal repercussions. Operators are also required to obtain further certification if they have complied with previous issues of this directive, as compliance with prior issues does not suffice for the current directive (section 9/86).
