COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (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 or aeronautical product 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.
Fokker F100 (F28 Mk 100) Series Aeroplanes
AD/F100/58 Engine- Operating Limits and Warnings 2/2003
Applicability: All Fokker 100 (F28 Mk 100) Series aeroplanes with Rolls Royce Tay 650-15 engines installed.
Requirement: Action in accordance with Netherlands AD ( BLA) 2002-119.
Note: Netherlands AD (BLA). 2002-119 refers.
Compliance: As detailed in the requirement document with a revised effective date of 20 February 2003.
This Airworthiness Directive becomes effective on 20 February 2003.
Background: Rolls Royce TAY engine as installed in Fokker 100 aircraft has low fan flutter margin and can result in fan blade failures when operated under certain speed ranges. This directive mandates installation of modified warning systems and introduces new engine operating limits and maintenance requirements. These are in addition to those mandated per AD/TAY/2 ( BLA 1997-119/2) and AD/F100/50 (BLA 2002-063).

Delegate of the Civil Aviation Safety Authority 9 January 2003
The above AD is notified in the Commonwealth of Australia Gazette on 29 January 2003.
Overview
The Civil Aviation Regulations 1998, enacted in 1998, are a critical piece of Australian legislation governing civil aviation safety. These regulations were introduced to ensure that all civil aviation operations within Australia are conducted with the utmost safety and efficiency, in line with international standards. The Civil Aviation Safety Authority (CASA) is the enforcing body, responsible for ensuring compliance with these regulations through various directives and oversight measures. One such directive is the Airworthiness Directive (AD) issued under subregulation 39.1 (1) of the Civil Aviation Regulations 1998, aimed at addressing specific safety concerns related to certain aircraft models. For instance, AD/F100/58 issued on 2 February 2003 addresses the low fan flutter margin in Rolls Royce Tay 650-15 engines installed in Fokker 100 (F28 Mk 100) Series aeroplanes, requiring modifications to operating limits and warning systems to prevent potential fan blade failures.
Scope and Application
This Airworthiness Directive issued under the Civil Aviation Regulations 1998 applies specifically to all Fokker 100 (F28 Mk 100) Series aeroplanes equipped with Rolls Royce Tay 650-15 engines. The directive is issued by the Civil Aviation Safety Authority (CASA) delegate, Neville James Probert, and becomes effective on 20 February 2003. It requires that actions be taken in accordance with the Netherlands Airworthiness Directive (BLA) 2002-119, which addresses specific concerns related to engine fan flutter margins and the risk of fan blade failures when these engines are operated within certain speed ranges. The directive mandates the installation of modified warning systems and introduces new engine operating limits and maintenance requirements, supplementing those already in place under previous directives AD/TAY/2 (BLA 1997-119/2) and AD/F100/50 (BLA 2002-063). This Airworthiness Directive is notified in the Commonwealth of Australia Gazette on 29 January 2003 and is applicable across the Commonwealth of Australia, enforcing strict compliance to ensure the safety and airworthiness of affected aircraft.
Key Provisions
The Civil Aviation Regulations 1998 (CAR 1998) establish various safety requirements and standards for civil aviation within Australia. In particular, Part 39, Section 105, focuses on Airworthiness Directives, which are legally binding instructions issued by the Civil Aviation Safety Authority (CASA) to address safety concerns in specific aircraft models. The Airworthiness Directive (AD) referenced here, AD/F100/58, applies to all Fokker F100 (F28 Mk 100) Series aeroplanes equipped with Rolls Royce Tay 650-15 engines.
Under this directive, operators of the affected aircraft must comply with the requirements specified in Netherlands AD (BLA) 2002-119. This involves implementing modifications to the warning systems and adhering to new operating limits and maintenance procedures for the engines, which are critical to mitigating the risk of fan blade failure due to low fan flutter margins. These modifications and requirements are to be carried out in accordance with the instructions detailed in the referenced Netherlands AD, and compliance is mandated by 20 February 2003.
The AD imposes specific obligations on aircraft operators, including the necessity to follow the detailed instructions in Netherlands AD (BLA) 2002-119. This includes ensuring that the new warning systems are installed and that the new engine operating limits and maintenance schedules are strictly adhered to. Failure to comply with these requirements may result in the aircraft being deemed unairworthy, leading to grounding and potential legal repercussions.
Failure to comply with the provisions of this Airworthiness Directive can result in severe civil and criminal consequences. The exact penalties are not specified within the directive itself but can include fines, penalties, and potentially imprisonment for serious breaches of aviation safety regulations. The severity of the penalty may depend on the nature and extent of the non-compliance and its impact on aviation safety.
