Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, were established to regulate the safety of civil aviation within Australia. The regulations are designed to ensure that all aircraft meet specific safety standards to protect passengers, crew, and the general public. The problem this legislation aimed to address includes ensuring that aircraft are maintained to a standard that mitigates the risk of accidents or incidents caused by mechanical or electrical failures, including those that might arise from inadequate clearances or interference with wiring. The policy objective of this particular directive, as outlined in the AD/BEECH 55/84, is to prevent potential flight control interferences by mandating inspections of specific Beechcraft models to ensure that there is no electrical or mechanical interference with the flight control mechanisms. This is achieved by requiring inspections and necessary corrective actions to secure components, thus maintaining the integrity of the flight control systems.

Scope and Application

The Civil Aviation Regulations 1998, under PART 39 - 105, applies to the safety directives issued by the Civil Aviation Safety Authority (CASA) regarding specific aircraft models. In this instance, the regulation addresses the Beechcraft 55, 58, and 95-55 (Baron) Series aeroplanes. The directive applies to particular serial numbers of these models, as listed within the regulation, to ensure compliance with safety standards. The scope of this directive is geographically limited to the Commonwealth of Australia, impacting all operators and owners of the specified aircraft models within the Australian jurisdiction. This Airworthiness Directive mandates a specific inspection procedure to ensure that there is no interference or inadequate clearance between the flight control mechanism and any component located forward of the instrument, as per the Raytheon Mandatory Service Bulletin 27-3232 dated March 1999. If such interference is detected, the directive requires that all components be secured to eliminate any contact with the flight control mechanisms, as outlined in the same service bulletin. Exemptions apply if the operators have already carried out Raytheon Safety Communiqué No 149 dated August 1998 or its revision from November 1998. The directive becomes effective from 19 May 1999, with compliance required within 25 hours’ time in service after this date, or prior to further flight after the inspection has been completed.

Key Provisions

The key provisions of this Airworthiness Directive (AD/BEECH 55/84) are contained within section 2, which outlines the requirement for inspecting the Beechcraft 55, 58, and 95-55 (Baron) series aeroplanes for flight control interference with wiring. Specifically, section 2(1) mandates that an inspection must be conducted to check for any interference or inadequate clearance between the flight control mechanism and any component located forward of the instrument. This inspection must be performed in accordance with Raytheon Mandatory Service Bulletin (SB) 27-3232 dated March 1999. If interference or inadequate clearance is detected during the inspection, section 2(2) requires that all components must be secured clear of the flight control mechanisms, again following the guidelines in SB 27-3232. Note 1 clarifies that if Raytheon Safety Communiqué No 149 dated August 1998 or No 149 Rev 1 dated November 1998 has already been implemented, no further action is necessary. Note 2 references FAA AD 99-09-15 for additional context. The obligations imposed by this directive are detailed in section 1, which specifies the compliance timeline and conditions. Section 1(1) requires that the inspection must be carried out within 25 hours’ time in service after 19 May 1999. Section 1(2) further stipulates that the inspection must be completed prior to any subsequent flight after the inspection has been conducted. These requirements ensure that the aircraft are safe to operate and that any potential hazards identified in the inspection are promptly addressed. Breach of these requirements could have serious consequences. Although the specific penalties or consequences for non-compliance are not detailed in the directive, failure to adhere to Airworthiness Directives can result in severe civil and criminal penalties under the Civil Aviation Act 1988 and the Civil Aviation Regulations 1998. Non-compliance may lead to enforcement actions by the Civil Aviation Safety Authority (CASA), including fines, suspension or revocation of aircraft certificates, and potential criminal charges for individuals or entities responsible for the oversight of the aircraft. The severity of the penalties reflects the importance of adhering to airworthiness directives to maintain the safety and integrity of civil aviation operations.
