COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 106 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
CFM International Turbine Engines - CFM56 Series
AD/CFM56/4 Garrett Air Turbine Starter - Improved Clutch 8/94 Applicability: All CFM56-5A1 engines equipped with Garrett air turbine starter, P/N 3505582-1. Requirement: Incorporate CFM International Service Bulletin CFM56-5 No 80-003.
Note: DGAC AD 94-099(B) also refers.
Compliance: Unless previously accomplished, at the first starter shop visit after 21 July 1994 but no later than 31 December 1994.
Background: This Directive has been issued to prevent starter failures and consequent heat damage to the electronic engine control (FADEC) harnesses.
Overview
The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), were enacted to ensure the safety and efficiency of the civil aviation sector in Australia. The Civil Aviation Regulations 1998, particularly Part 39, address various safety directives, including Airworthiness Directives (ADs) that mandate specific maintenance and operational procedures to ensure aircraft remain safe to fly. This legislative instrument, F2006B08529, was introduced to address the specific issue of potential starter failures in CFM56-5A1 engines equipped with Garrett air turbine starters, P/N 3505582-1, which could lead to heat damage to the electronic engine control harnesses. The policy objective is to mitigate such risks through timely compliance with the specified service bulletin, ensuring the continued airworthiness of affected aircraft.
This legislative instrument mandates compliance with CFM International Service Bulletin CFM56-5 No 80-003, which requires that the specified starter modifications be implemented within a defined timeframe to prevent potential failures. The directive ensures that all relevant aircraft are maintained to a high safety standard, aligning with CASA’s overarching goal of maintaining and enhancing aviation safety in Australia. The requirement to adhere to this directive is clear, with compliance necessary at the first starter shop visit after 21 July 1994 but no later than 31 December 1994.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 106, encompasses various Airworthiness Directives (AD) aimed at ensuring the safety and reliability of civil aviation operations. This legislative instrument applies to all CFM56-5A1 engines equipped with a Garrett air turbine starter, P/N 3505582-1, within the Australian jurisdiction, thereby impacting the aviation industry's maintenance and operational protocols. The directive mandates the incorporation of CFM International Service Bulletin CFM56-5 No 80-003 to prevent starter failures and mitigate heat damage to the electronic engine control (FADEC) harnesses, which is critical for maintaining aircraft safety. The directive requires compliance with the specified actions unless they have already been performed, with a compliance deadline set for the first starter shop visit after 21 July 1994 but no later than 31 December 1994. This directive extends its regulatory reach by referencing DGAC AD 94-099(B).
Key Provisions
The main operative sections of the Civil Aviation Regulations 1998, specifically Part 39 - 106, pertain to the Airworthiness Directives for the CFM International Turbine Engines, specifically the CFM56 Series. The directive AD/CFM56/4 mandates that all CFM56-5A1 engines equipped with the Garrett air turbine starter, part number 3505582-1, must incorporate the changes outlined in CFM International Service Bulletin CFM56-5 No 80-003. This directive applies to all relevant engines and aims to prevent starter failures and subsequent heat damage to the electronic engine control (FADEC) harnesses.
The obligations under this directive require that the specified modifications be implemented unless they have already been carried out. Compliance is necessary at the first starter shop visit following the directive's issuance on 21 July 1994, but no later than 31 December 1994. Failure to adhere to these requirements could result in non-compliance with airworthiness standards, potentially leading to severe safety implications.
The obligations extend to all entities and parties involved in the maintenance and operation of CFM56-5A1 engines, including airlines, maintenance providers, and aircraft operators. These parties must ensure that all applicable engines are inspected, and the necessary modifications are implemented within the stipulated timeframe. This includes documenting the compliance process and retaining records that demonstrate adherence to the directive.
The consequences for non-compliance with the Airworthiness Directives can be significant. While the Civil Aviation Regulations 1998 do not explicitly state specific offences or penalties in this context, breaches of airworthiness directives can result in enforcement actions by the Civil Aviation Safety Authority (CASA). Potential outcomes include fines, operational restrictions, or even the grounding of aircraft until compliance is achieved. The severity of penalties can vary depending on the extent of non-compliance and any resultant safety risks identified.
