SCHEDULE OF AIRWORTHINESS DIRECTIVES

 



CFM International Turbine Engines - CFM56 Series

 

AIRWORTHINESS DIRECTIVE


For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/CFM 56/14 and issues the following AD under subregulation 39.1 (1) of CAR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.

 

AD/CFM56/14

Amdt 1


Fuel Filter Cover Attachment Inspection 3/2000

 

Applicability: CFM International (CFMI) CFM56-5, CFM56-5B & CFM56-5C engines.

Requirement: 1. Inspect fuel filter cover attachment hardware in accordance with CFMI Service Bulletin CFM56-5 73-136 Rev 2, or CFM56-5B 73-056 Rev 2 or CFM56-5C 73-

073 Rev 2, as applicable.

Compliance with the original issue of this Directive satisfies Requirement 1.

2. Modify the engine driven fuel pump to provide improved filter cover retention in accordance with CFMI Service Bulletin CFM 56-5 73-A143, or CFM56-5B

73-A062 or CFM56-5C 73-A078, as applicable.

Compliance with Requirement 2 constitutes terminating action for this Directive.

Note: DGAC 98-427 (B) R2 also refers.

Compliance: 1. Unless previously accomplished, no later than the next A check after the effective date of this Directive.

2. No later than 31 December 2004.

This Amendment becomes effective on 23 March 2000.

Background:  The fuel filter cover is secured with six bolts torqued in helicoil inserts. Loose inserts have been discovered in two aircraft which have resulted in heavy fuel loss in flight.

This amendment requires modification of the engine driven pump to provide an improved fuel filter cover retention design.

The original issue of this Airworthiness Directive became effective on 7 October 1999.

Overview

The Civil Aviation Regulations 1998, as amended by the Legislative instrument F2006B08519, address the safety concerns associated with the CFM International Turbine Engines, specifically the CFM56 series. Enacted by the Civil Aviation Safety Authority (CASA), this legislation was introduced to address the identified unsafe condition of the fuel filter cover attachment hardware in the CFM56-5, CFM56-5B, and CFM56-5C engines. The policy objective is to ensure the airworthiness of these engines by mandating specific inspections and modifications. The directive requires inspecting the fuel filter cover attachment hardware and modifying the engine-driven fuel pump to improve filter cover retention, aiming to prevent potential fuel loss during flight. This directive became effective on 23 March 2000 and was published in the Commonwealth of Australia Gazette on 23 February 2000.

Scope and Application

This legislative instrument, titled "Civil Aviation Regulations 1998," pertains specifically to Part 39, which deals with airworthiness directives, and particularly targets the CFM International Turbine Engines of the CFM56 Series. The directive applies to aircraft equipped with CFMI CFM56-5, CFM56-5B, and CFM56-5C engines. The regulation mandates inspections and modifications to the fuel filter cover attachment hardware to address safety concerns that have arisen from loose inserts leading to fuel loss in flight. Compliance with the directive is required within specific timeframes, either by the next A check following the effective date or by a specified deadline of 31 December 2004. The geographic reach of this regulation is national, as it applies throughout Australia, and it extends to all aircraft within the specified categories operating under the oversight of the Civil Aviation Safety Authority (CASA). The directive also references additional regulatory documents for further guidance and compliance.

Key Provisions

The key operative sections of this Civil Aviation Regulation mandate specific actions concerning CFM International Turbine Engines of the CFM56 series. Section 39.1(1) of the Civil Aviation Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) delegate to issue Airworthiness Directives (ADs) to address safety concerns. In this instance, AD AD/CFM 56/14 is revoked, and AD/CFM56/14 Amendment 1 is issued, which requires inspections and modifications to the fuel filter cover attachment hardware of specified CFM56 engines (section 3). The applicability section identifies the affected engines (section 3(a)), while the requirement section outlines the necessary actions, including inspection and modification of the engine-driven fuel pump (section 3(b)). The compliance section specifies the timeframes for these actions, with inspections needing to be completed by the next A check post the directive's effective date and modifications by 31 December 2004 (section 3(c)). The obligations imposed by this Act require relevant parties, such as aircraft operators and maintenance providers, to inspect the fuel filter cover attachment hardware of the affected CFM56 engines in accordance with the specified service bulletins (section 3(b)). Operators must ensure that these inspections and subsequent modifications are conducted within the prescribed timeframes. Compliance with the AD is mandatory, and failure to adhere to the stipulated actions and deadlines could result in the aircraft being deemed non-airworthy. The Act imposes serious consequences for non-compliance with the AD. Operators failing to meet the requirements risk severe penalties, including potential grounding of their aircraft. The safety directive aims to prevent unsafe conditions, such as those that led to heavy fuel loss in flight due to loose helicoil inserts in the fuel filter cover. By mandating these inspections and modifications, the regulation seeks to ensure the continued airworthiness and safety of the aircraft involved. The potential for civil or criminal penalties is not explicitly stated in the directive but is implied by the mandatory nature of compliance and the safety implications of non-compliance.
