Overview

The Civil Aviation Regulations 1998, under the Civil Aviation Act 1988, were enacted to regulate the safety of civil aviation in Australia. These regulations address gaps in ensuring the airworthiness of aircraft and aeronautical products, thereby protecting the safety of the public and the aviation industry. This particular Airworthiness Directive (AD) was issued by the Civil Aviation Safety Authority (CASA) to address an unsafe condition identified in certain models of Rotax piston engines. The policy objective of this directive is to mandate corrective actions to mitigate the risk of engine stoppage due to damage to the stator ignition cable insulation, which could potentially result in electrical short circuits. By requiring the inspection and, if necessary, the replacement of the stator assembly, the directive aims to maintain the airworthiness of the affected aircraft and ensure continued safe operation within the Australian aviation sector.

Scope and Application

The Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998 applies specifically to Rotax 912 and 914 series engines within particular serial number ranges. The directive mandates the inspection and repair or replacement of the ignition stator assembly to address potential electrical issues that could result in engine stoppage. The AD is designed to enhance the safety of aircraft utilising these specific engine models by requiring corrective actions before further flight or within a defined timeframe. This directive's compliance obligations are jurisdictional, applying within the Commonwealth of Australia, and it extends its application through the Civil Aviation Regulations 1998, which can be further specified through subordinate instruments or service bulletins as referenced. The AD is effective from 7 April 2000, and failure to comply with the outlined requirements could result in safety risks that CASA seeks to mitigate through this regulatory action.

Key Provisions

The Airworthiness Directive (AD) issued under section 39.1 (1) of the Civil Aviation Regulations 1998 (CAR 1998) pertains specifically to certain Rotax 912 and 914 series engines. The directive mandates that owners and operators of affected engines, specifically those with serial numbers within the ranges mentioned in the applicability section, must inspect the ignition stator assembly as per the instructions in Section 3.1 of either Rotax Aircraft Service Bulletin SB-912-026 Revision 3 or SB-914-014 Revision 3, both dated December 1999, depending on the engine series. If any discrepancies are found during this inspection, they must be repaired accordingly. Furthermore, the directive requires the replacement of the stator assembly as outlined in Section 3.2 of the respective service bulletin. The AD imposes several obligations on the parties it governs. Firstly, it requires a thorough inspection of the ignition stator assembly to ensure there is no damage that could lead to an electrical short circuit and subsequent engine stoppage. This inspection must be conducted before further flight after the effective date of the directive. Secondly, the directive mandates the replacement of the stator assembly. This replacement must occur before the next 100-hour inspection or by 15 May 2000, whichever comes first. Failure to comply with these obligations could result in the aircraft or aeronautical product being deemed unairworthy, potentially leading to grounding and other regulatory consequences. Breach of the provisions of this AD can result in serious consequences. The AD specifies that non-compliance with the requirements can lead to the aircraft being deemed unairworthy. This could involve enforcement actions by the Civil Aviation Safety Authority (CASA), including the imposition of fines or other penalties. While the AD itself does not explicitly state the maximum penalties, under the broader framework of the Civil Aviation Act 1988 and associated regulations, non-compliance can attract significant financial penalties and, in severe cases, criminal charges. CASA may also issue a Notice of Violation or take further regulatory action to ensure compliance with aviation safety standards.
