AD/PW100/5 Amdt 1 - Intercompressor Case Fire

Overview

The Civil Aviation Regulations 1998, specifically Part 39, addresses numerous safety directives to ensure the airworthiness of aircraft engines, including those of Pratt and Whitney Canada. The regulations were enacted by the Commonwealth of Australia to ensure the safety of civil aviation by setting stringent standards for aircraft operations and maintenance. This legislative instrument targets a particular safety concern, namely intercompressor case fires in PW100 series turbine engines, by mandating compliance with specific technical requirements as outlined by Transport Canada. The objective is to mitigate risks associated with these engines and maintain high safety standards in Australian civil aviation, thereby protecting passengers, crew, and the public. The Civil Aviation Safety Authority enforces these regulations, ensuring that all aircraft operators adhere to the stipulated directives to prevent potential hazards.

Scope and Application

The Civil Aviation Regulations 1998, under PART 39 - 106, specifically address the safety directives for Pratt and Whitney Canada turbine engines, particularly the PW100 series, through AD/PW100/5 Amendment 1, which pertains to intercompressor case fires. This regulation applies to a range of Pratt and Whitney Canada engines, including the PW118A, PW123, PW123AF, PW124B, PW125B, PW126, and PW1246A models. The Act mandates compliance with the technical requirements outlined in Transport Canada's Airworthiness Directive CF-91-26R1, ensuring that any actions taken to mitigate the risk of intercompressor case fires are in accordance with these specified standards. The application of this regulation is enforced throughout the Commonwealth of Australia, thereby impacting any aviation entities operating within the national jurisdiction. The Directive came into effect on 6 March 1992, and subsequent amendments have been made to incorporate additional inspection requirements and to detail specific termination actions as stipulated in the Requirement Document. No exclusions, exemptions, or thresholds are explicitly mentioned in the text, suggesting that the directive applies broadly to the specified engines within the applicable jurisdiction.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 106, contains a schedule of airworthiness directives issued by the Civil Aviation Safety Authority (CASA). One such directive, AD/PW100/5Amdt 1, pertains to Pratt and Whitney Canada Turbine Engines - PW100 Series, and it mandates action concerning intercompressor case fires (sections 3 and 4). This directive applies to PW118A, PW123, PW123AF, PW124B, PW125B, PW126, and PW1246A engines (section 3). The requirement for compliance is that the engines must adhere to the Technical Requirements of Transport Canada Airworthiness Directive CF-91-26R1 (section 4). The directive became effective on 6 March 1992, with compliance details specified in the Requirement Document. Entities and parties governed by this directive must ensure that the specified engines are modified or maintained according to the Technical Requirements of Transport Canada Airworthiness Directive CF-91-26R1. This involves implementing the necessary actions to mitigate the risk of intercompressor case fires, as outlined in the Requirement Document. The directive mandates compliance from the date it became effective, and any modifications or maintenance must be completed in accordance with the specified technical requirements. Failure to comply with the AD/PW100/5Amdt 1 directive may result in civil or criminal consequences. While the exact penalties are not specified in the text, non-compliance with CASA airworthiness directives generally can lead to enforcement actions, which may include fines, orders to rectify the non-compliance, or in severe cases, grounding of the aircraft until the issues are addressed. The specific penalties would depend on the nature and severity of the non-compliance, and could be pursued under the broader provisions of the Civil Aviation Act 1988 or related regulations. It is crucial for operators and maintainers of these engines to ensure full compliance to avoid any legal repercussions.
