AD/BEECH 23/27 Amdt 1 - Engine Firewall Aluminium Fittings

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, form a crucial part of the regulatory framework ensuring the safety and efficiency of civil aviation within the country. Specifically, Part 39 - 105 of these Regulations includes the Civil Aviation Safety Authority Schedule of Airworthiness Directives, which mandates certain safety measures for various aircraft models. One such directive, AD/BEECH 23/27 Amendment 1, addresses engine firewall aluminium fittings for certain Beechcraft 19, 23, and 24 series aeroplanes. This directive was introduced to ensure that these specific aircraft models meet the necessary safety standards, thereby mitigating risks associated with the identified issue. The policy objective behind such specific directives is to maintain high safety standards in civil aviation, ensuring the protection of passengers, crew, and the general public.

Scope and Application

The Civil Aviation Regulations 1998, under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, specifically addresses the Beechcraft 19, 23 and 24 Series Aeroplanes through AD/BEECH 23/27 Amendment 1, which pertains to engine firewall aluminium fittings. This regulation applies to specific models and serial numbers of these aircraft, namely Models A23-19, 19A, and B19 with serial numbers ranging from MB-1 to MB-677; Models 23, A23, A23A, B23, and C23 with serial numbers from M-1 to M1545; Models A23-24 and A24 with serial numbers from MA-1 to MA-368; and Models A24R and B24R with serial numbers from MC-1 to MC-341. The directive mandates compliance with Beechcraft Service Instruction No. 0638-240, Revision 1, and requires actions to be taken before 1 July 1976. Notably, compliance with the preceding version of this directive is deemed sufficient to satisfy the requirements of this amended directive. This regulation is applicable across the Commonwealth of Australia and is enforced by CASA, ensuring adherence to safety standards within the aviation industry.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, contains an Airworthiness Directive (AD) that applies to certain models of Beechcraft 19, 23, and 24 series aeroplanes. The AD in question, AD/BEECH 23/27 Amendment 1, pertains to the engine firewall aluminium fittings of these aircraft (Section 1). The directive mandates compliance with Beechcraft Service Instruction No. 0638-240, Revision 1, to address specific issues with the engine firewall aluminium fittings. This requirement must be met before 1 July 1976, with compliance to the preceding issue of this directive considered as meeting the requirements of this current directive (Section 2). The AD imposes specific obligations on the owners and operators of the affected aircraft models. These parties must ensure that the engine firewall aluminium fittings of their aeroplanes are inspected and, if necessary, modified or replaced according to the specifications detailed in Beechcraft Service Instruction No. 0638-240, Revision 1. This directive applies to Models A23-19, 19A, and B19 with serial numbers MB-1 to MB-677; Models 23, A23, A23A, B23, and C23 with serial numbers M-1 to M1545; Models A23-24 and A24 with serial numbers MA-1 to MA-368; and Models A24R and B24R with serial numbers MC-1 to MC-341 (Section 3). Failure to comply with the AD/BEECH 23/27 Amendment 1 could result in significant legal and safety consequences. While the specific civil or criminal penalties for non-compliance are not detailed within the text of the directive, general provisions of the Civil Aviation Act 1988 and the Civil Aviation Regulations 1998 would apply. These may include fines, the grounding of the aircraft until compliance is achieved, or other enforcement actions deemed necessary by the Civil Aviation Safety Authority. Ensuring adherence to the AD is critical to maintaining the airworthiness and safety of the specified aircraft models.
