AD/BEECH 33/31 Amdt 1 - Sponge Filled Fuel Reservoir Tanks

Overview

The Civil Aviation Regulations 1998, specifically Part 39, was enacted to regulate civil aviation operations in Australia, including the maintenance and airworthiness of aircraft. The 1998 Regulations were updated with Amendment 1, issued in 1986, to address specific safety concerns related to certain aircraft models. One such amendment, AD/BEECH 33/31 Amendment 1, pertains to the Beechcraft 33 and 35-33 (Debonair/Bonanza) series aeroplanes, focusing on the sponge-filled fuel reservoir tanks. This amendment was introduced to mitigate safety risks associated with the original design of the fuel reservoir tanks, which were prone to certain issues as outlined in Beechcraft Mandatory Service Bulletin No. 2109. The objective of this legislation is to ensure the continued airworthiness and safety of these aircraft by requiring specific actions and compliance checks in accordance with the updated service bulletin. The amendment was enacted by the Civil Aviation Safety Authority, under the authority granted by the Civil Aviation Act 1988, to enforce stringent safety standards and procedures. The policy objective behind this specific regulation is to enhance the safety of fuel reservoir tanks in the specified Beechcraft models, ensuring that they operate within safe parameters by adopting improved components as recommended in the updated service bulletin. The requirement mandates an inspection within 25 hours of time in service after 31 July 1985, and further inspections as directed, to maintain the airworthiness and safety of these aircraft.

Scope and Application

The Civil Aviation Regulations 1998, as detailed in Part 39 - 105, specifically address the airworthiness directives for the Beechcraft 33 and 35-33 (Debonair/Bonanza) series aeroplanes, with Amendment 1 focusing on sponge-filled fuel reservoir tanks. This legislation applies to all models of the specified Beechcraft series, as delineated in Beechcraft Mandatory Service Bulletin No. 2109. The requirement is for compliance with the actions outlined in this bulletin. Operators and owners of these aircraft are obligated to inspect the fuel reservoir tanks within 25 hours of time in service after 31 July 1985 and to adhere to any further inspection directives provided in the "Compliance" section of Service Bulletin 2109. The regulation extends to ensuring the use of improved reservoir foam inserts available through Beechcraft, as per the updated bulletin. The scope of this legislation is national, falling under the purview of the Commonwealth of Australia and administered by the Civil Aviation Safety Authority. There are no exclusions, exemptions, or thresholds specified in this particular directive, and its application is direct without reliance on subordinate instruments for extension or restriction.

Key Provisions

The Civil Aviation Regulations 1998, Part 39 – 105, specifically Amendment 1 (AD/BEECH 33/31 Amdt 1) concerning the Beechcraft 33 and 35-33 (Debonair/Bonanza) series aeroplanes, sets forth detailed requirements for the sponge-filled fuel reservoir tanks. According to section (1), these regulations apply to all models specified in Beechcraft Mandatory Service Bulletin No. 2109. The key requirement, as detailed in section (2), is that action must be taken in accordance with the instructions provided in Beechcraft Mandatory Service Bulletin No. 2109. This involves inspecting the sponge-filled fuel reservoir tanks within 25 hours of time in service after 31 July 1985, and subsequently following the directions outlined in the "Compliance" section of Service Bulletin 2109. The obligations imposed on parties governed by this legislation include ensuring that all inspections and actions are carried out in strict compliance with the specified Beechcraft bulletin. Operators of these aircraft must diligently adhere to the timelines and procedures detailed in the bulletin, which now references the improved reservoir foam inserts available from Beechcraft. This ongoing compliance ensures the airworthiness of the aircraft, aligning with safety standards set by the Civil Aviation Safety Authority. In the event of non-compliance with these airworthiness directives, there are significant consequences. Section (3) outlines that breaches of these requirements may result in enforcement actions, including the possibility of penalties for non-compliance. The severity of these penalties can include financial fines, and in more severe cases, the grounding of the aircraft until compliance is achieved. These measures are designed to enforce adherence to safety standards and ensure that all aircraft maintain their airworthiness as mandated by the Civil Aviation Regulations 1998.
