AD/BEECH 23/37 - Engine Hose Assembly

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, form a crucial framework for ensuring the safety and efficiency of civil aviation within the country. Among these regulations, Part 39 - 105 specifically addresses airworthiness directives which are essential for maintaining the safety standards of various aircraft models. One such directive, AD/BEECH 23/37, pertains to the Beechcraft 19, 23 and 24 series aeroplanes, focusing on the engine hose assembly. This directive was introduced to address specific safety concerns related to the engine hose assembly of these aircraft models, ensuring compliance with safety instructions issued by Beechcraft, thereby mitigating potential risks and maintaining airworthiness. The directive AD/BEECH 23/37 outlines the applicability to certain serial numbers of the Beechcraft models and mandates compliance within 100 hours of time in service after 31 October 1978, as per Beechcraft Service Instruction No. 0998. The policy objective behind this regulation is to ensure that these aircraft meet the required safety standards, thereby enhancing the overall safety of civil aviation in Australia.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives under the Civil Aviation Regulations 1998 specifically applies to the Beechcraft 19, 23, and 24 Series Aeroplanes, particularly focusing on the engine hose assembly for certain serial numbers. This directive is relevant for operators and owners of the Model B19 with serial numbers ranging from MB-844 to MB-890, and Model C23 with serial numbers ranging from M-1935 to M-2015, M-2017 to M-2029, and M-2031 to M-2038. The directive mandates compliance with Beechcraft Service Instruction No. 0998, which must be actioned within 100 hours of the aircraft's time in service after 31 October 1978. The regulations fall under the jurisdiction of the Commonwealth of Australia and are enforced by the Civil Aviation Safety Authority, ensuring that the specified aircraft meet required safety standards. There are no stated exclusions or exemptions within the text, and compliance is mandatory for the specified models and serial numbers. The authority to extend or restrict the application of these directives is reserved through subordinate instruments, ensuring flexibility in responding to emerging safety issues.

Key Provisions

The main sections of the Civil Aviation Regulations 1998, PART 39 - 105 pertaining to the Beechcraft 19, 23, and 24 series aeroplanes, particularly AD/BEECH 23/37, focus on the engine hose assembly for specific models and serial numbers. The regulation applies to Model B19 with serial numbers MB-844 to MB-890 and Model C23 with serial numbers M-1935 to M-2015, M-2017 to M-2029, and M-2031 to M-2038 (section 10/78). The primary requirement is for the action to be taken in accordance with Beechcraft Service Instruction No. 0998. Compliance with this directive must be achieved within 100 hours of the aircraft being in service after 31 October 1978. The obligations imposed by these regulations are specific and mandatory for the relevant aircraft operators. They must ensure that the engine hose assembly of their Beechcraft 19, 23, and 24 series aeroplanes, within the specified serial number ranges, is addressed according to Beechcraft SI No. 0998. This action must be completed within 100 hours of the aircraft being in service after the given date of 31 October 1978. The operators are responsible for scheduling and performing the necessary maintenance or modifications to comply with this directive to ensure the safety and airworthiness of the aircraft. Failure to comply with these provisions can result in significant legal consequences. The Civil Aviation Safety Authority (CASA) can take enforcement action against operators who do not adhere to the airworthiness directives. Depending on the severity of the non-compliance, penalties can include fines, legal action, or even the grounding of the aircraft until the required compliance is achieved. In serious cases, there may be criminal charges brought against the responsible parties, leading to potential imprisonment. The exact penalties are not specified in the text, but they are designed to ensure strict adherence to safety standards to prevent accidents and ensure public safety.
