Overview
The Civil Aviation Regulations 1998, as amended, constitute a fundamental legislative instrument for ensuring the safety and regulation of civil aviation in Australia. Specifically, the Airworthiness Directive AD/ALF/19 issued by the Civil Aviation Safety Authority (CASA) under subregulation 39.1(1) of the Civil Aviation Regulations 1998, addresses critical safety concerns related to the combustion chamber liners of Allied Signal (Lycoming) Turbine Engines, models ALF502 and LF507 Series. This directive, enacted to respond to reports of combustion chamber liner failures that could lead to engine fires, mandates specific inspection and maintenance actions to mitigate such risks. The directive aims to ensure the continued airworthiness of the affected engines by requiring compliance with the Federal Aviation Administration's Airworthiness Directive 2002-22-06. This legislative instrument reflects the commitment of the Australian government to align with international safety standards and uphold the highest levels of aviation safety within its jurisdiction.
Scope and Application
The Airworthiness Directive AD/ALF/19 pertains to Honeywell ALF502R and LF507 Series engines equipped with a combustion chamber liner part number 2-131-520-03, issued by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998. This directive mandates specific actions including the initial inspection, repetitive inspection, and replacement of combustion chamber liner assemblies, as outlined in FAA AD 2002-22-06. These requirements are set in response to reported failures of combustion chamber liners that led to burn-through, posing a risk of engine fires. The directive applies to all relevant aircraft or aeronautical products within the specified category and must be adhered to by the entities responsible for maintaining these engines. The directive is effective from 23 January 2003 and was published in the Commonwealth of Australia Gazette on 18 December 2002. The scope of this legislation is national, applying across all jurisdictions within Australia, ensuring consistent safety standards for aviation operations.
Key Provisions
The main operative sections of this Airworthiness Directive (AD) pertain to the inspection, repetitive inspection, and replacement of combustion chamber liner assemblies for specific Honeywell engines. According to section 1, the AD applies to ALF502R and LF507 Series engines with combustion chamber liner part number 2-131-520-03 installed (section 1). The directive mandates these actions to address a reported unsafe condition that could lead to engine fires (section 1). The requirement section specifies that the inspections and replacements must be conducted in accordance with FAA AD 2002-22-06 (section 1). Furthermore, the compliance section dictates that these actions must be taken by 23 January 2003, with the AD becoming effective on the same date (section 1).
The obligations imposed by this AD on the relevant parties, such as aircraft owners, operators, and maintenance providers, include ensuring that the specified inspections and replacements are carried out on the affected engines. This involves adhering to the detailed instructions provided in FAA AD 2002-22-06, which includes the frequency and procedures for inspections, as well as the criteria for determining when a combustion chamber liner assembly should be replaced. It is essential for these parties to maintain accurate records of the inspections and any actions taken, as well as to ensure that the engines remain airworthy in compliance with the AD.
Failure to comply with this AD can result in serious consequences. While the specific civil or criminal penalties are not detailed within the AD itself, non-compliance could potentially lead to significant safety risks and violations of aviation regulations. Such violations might attract penalties under the Civil Aviation Act 1988 and the Civil Aviation Regulations 1998, which could include fines or other enforcement actions. The severity of the penalties would depend on the extent of non-compliance and its impact on aviation safety.
