AD/BEECH 23/35 - Flap Control Assembly

Overview

The Civil Aviation Regulations 1998, as part of the Civil Aviation Safety Authority’s (CASA) mandate, were enacted to establish a comprehensive framework for maintaining and ensuring the safety and airworthiness of aircraft operating within Australia. This legislation was introduced to address the need for stringent regulatory oversight in civil aviation, particularly in ensuring that aircraft meet safety standards to protect passengers, crew, and the general public. The policy objective behind these regulations is to prevent accidents and incidents through consistent and rigorous safety standards, thus maintaining public confidence in the safety of air travel. The specific legislative instrument F2006B03749 pertains to Beechcraft 19, 23, and 24 Series Aeroplanes, detailing the airworthiness directives for the flap control assembly. This directive mandates specific actions, such as inspections and modifications, to be undertaken in accordance with Beechcraft Service Information No. 0940 and references Federal Aviation Administration Airworthiness Directive 78-04-01 Amendment 39-3139. Compliance with these directives is critical to ensuring the continued safe operation of these aircraft models, with inspections required at intervals not exceeding 100 hours of time in service until modifications are implemented, and all modifications must be completed by 1 January 1979.

Scope and Application

The Civil Aviation Regulations 1998, as part of the Commonwealth of Australia's regulatory framework, govern a wide range of activities related to civil aviation safety, including the issuance of airworthiness directives. Specifically, Part 39 - 105 pertains to directives aimed at ensuring the safe operation of aircraft. One such directive, AD/BEECH 23/35, applies to the flap control assembly of Beechcraft 19, 23, and 24 series aeroplanes, covering specific model variants and serial numbers. This directive mandates regular inspections and modifications to the flap control assembly to maintain airworthiness standards, with a compliance requirement to inspect at intervals not exceeding 100 hours of time in service and to implement modifications before 1 January 1979. The geographic and jurisdictional reach of these regulations is national, as they apply to all civil aviation activities within Australia, overseen by the Civil Aviation Safety Authority. The directive is precise in its application, focusing solely on the specified models and serial numbers, and does not extend to other aircraft or components unless explicitly stated in separate directives or amendments.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39, establish the regulatory framework for ensuring the airworthiness of aircraft in Australia. One of the key sections within this framework is the Schedule of Airworthiness Directives, which mandates specific actions to maintain the safety of aircraft. For instance, AD/BEECH 23/35 (4/78) pertains to the Beechcraft 19, 23, and 24 series aeroplanes and addresses the flap control assembly. This directive applies to all models of these aircraft with specific serial numbers, ranging from M-1 to MB-866, MA-1 to MA-368, and MC-2 to MC-536. The directive requires that the flap control assembly be inspected at intervals not exceeding 100 hours of time in service. This ongoing inspection is crucial to ensure that the aircraft's flap control system functions correctly and safely. Additionally, the directive mandates that modifications be made to the flap control assembly before 1 January 1979. These modifications are outlined in Beechcraft Service Information (SI) No. 0940 and are intended to address any identified safety concerns or deficiencies. Compliance with these requirements is essential to maintain the airworthiness of the affected aircraft. Entities governed by this directive, such as aircraft operators and maintenance organisations, must adhere to the outlined inspection and modification requirements. This includes scheduling regular inspections of the flap control assembly within the specified time intervals and ensuring that the necessary modifications are completed before the deadline. Failure to comply with these obligations can result in serious safety risks and potential regulatory penalties. The directive references FAA AD 78-04-01 Amendment 39-3139, indicating the international alignment of safety standards and the importance of adhering to these directives to ensure consistent safety across the aviation industry. Failure to comply with the requirements set out in AD/BEECH 23/35 (4/78) can lead to significant consequences. The Civil Aviation Safety Authority (CASA) can impose penalties for non-compliance, which may include fines, suspension or revocation of airworthiness certificates, and other regulatory actions. The severity of these penalties can vary depending on the nature and extent of the non-compliance. It is imperative for all parties involved to ensure strict adherence to the directive to avoid these adverse outcomes and to maintain the highest standards of aviation safety.
