AD/BEECH 55/21 - Fuel Line Chafing

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, are a comprehensive set of rules governing civil aviation within Australia. Among its various provisions, Part 39 - 105 pertains to airworthiness directives issued by the Civil Aviation Safety Authority. One such directive, AD/BEECH 55/21, targets fuel line chafing in specific models of Beechcraft aeroplanes, namely the 55, 58, and 95-55 (Baron) series. This directive was introduced to address safety concerns arising from potential fuel line damage due to chafing, which could lead to fuel leaks and subsequent fire hazards. The requirement is for aircraft operators to implement corrective actions in line with Beechcraft Service Instruction No. 0419-281, with compliance expected not later than the next 100-hour inspection following 15 April 1971. The overarching policy objective is to ensure the continued airworthiness and safety of these aircraft models by mitigating risks associated with fuel line chafing.

Scope and Application

The Civil Aviation Regulations 1998, as amended, specifically under PART 39 - 105, encompasses the Civil Aviation Safety Authority’s Schedule of Airworthiness Directives, which pertains to certain types of aircraft. This regulation applies to the Beechcraft 55, 58, and 95-55 (Baron) Series aeroplanes, particularly those within the Model 58 range and serial numbers TH-1 to TH-92, TH-110, and TH-114. The directive mandates compliance with Beechcraft Service Information No. 0419-281 concerning the issue of fuel line chafing. Compliance with this directive is required to be addressed not later than the next 100 hourly inspection after 15 April 1971, ensuring that the specified aircraft meet the necessary safety standards. This regulation is applicable on a national level throughout Australia, enforced by the Civil Aviation Safety Authority under the overarching authority of the Commonwealth of Australia.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 105, include specific Airworthiness Directives (ADs) aimed at ensuring the safety of aircraft operations. In this context, AD/BEECH 55/21 pertains to the Beechcraft 55, 58, and 95-55 (Baron) series aeroplanes, focusing on the issue of fuel line chafing (section 3/71). This directive applies to Model 58 aircraft with serial numbers (S/Nos) TH-1 to TH-92, TH-110, and TH-114. The requirement is that these aircraft must comply with Beechcraft Service Information (SI) No. 0419-281, which provides detailed instructions on addressing the identified safety issue. The obligations imposed by this directive are clear and straightforward. Owners and operators of the specified Beechcraft models must ensure that the fuel lines are inspected and any signs of chafing or damage are addressed as per the instructions outlined in the referenced Beechcraft SI. This inspection must occur no later than the next 100 hourly inspection following the effective date of the directive, which is 15 April 1971. Failure to comply with these requirements may compromise the safety of the aircraft and could lead to severe consequences. Non-compliance with the Airworthiness Directives outlined in the Civil Aviation Regulations 1998 can result in significant legal and safety repercussions. The regulations stipulate that any breach of these directives may lead to enforcement actions by the Civil Aviation Safety Authority (CASA). Potential penalties can include fines and other sanctions that could impact the operator's ability to conduct commercial flights. In severe cases, CASA may impose more stringent measures, such as grounding the aircraft until the required actions are satisfactorily completed. These measures are in place to ensure that all aircraft meet the necessary safety standards and to protect the public from potential hazards.
