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 revokes Airworthiness Directive (AD) AD/B767/141 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 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.
Boeing 767 Series Aeroplanes
AD/B767/141
Amdt1
Reduced Acceleration and Climb Performance 8/2001
DM
Applicability: Boeing Model 767-200, 767-300 series aeroplanes equipped with Pratt & Whitney Model PW 4000 series engines.
Requirement: Revise the Aircraft Flight Manual (AFM) by inserting a copy of FAA Airworthiness Directive (AD) 2001-01-10 with Boeing Telex M-7200-00-02672, dated 1 November 2000, including the performance adjustments in “Performance for Operations of PW4000 Series Engines with FB2B or FB2T Fans Installed, 767-200/767-300”.
When the information in Boeing Telex M-7200-00-02672 and its attachments have been incorporated as a general revision of the AFM, the FAA AD and the telex and its attachments are to be removed from the AFM.
Note: FAA AD 2001-01-10 Amendment 39-12080 refers.
Compliance: Unless accomplished earlier, within 30 days from the effective date of this Directive.
This Amendment becomes effective on 12 July 2001.
Background: This Directive is being issued to correct the condition of Fan Thrust Deterioration Mode (FTDM) present on some PW4000 series engines fitted with early production fan blades. The thrust deterioration is due to erosion of fan blade’s leading edge and results in reduced acceleration and climb performance, relative to performance data in the AFM. The reduced thrust may result in runway overruns or impact with an obstacle or terrain.
This amendment is being issued to correct the FAA AD referred.
Eugene Paul Holzapfel
Delegate of the Civil Aviation Safety Authority 21 June 2001
The above AD is notified in the Commonwealth of Australia Gazette on 27 June 2001.

Overview
The Civil Aviation Regulations 1998, specifically PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY SCHEDULE OF AIRWORTHINESS DIRECTIVES, was enacted to ensure the safety and airworthiness of aircraft operating in Australia. This regulation was introduced to address potential safety issues and ensure that aircraft meet necessary safety standards, thereby preventing accidents and enhancing aviation safety. The Civil Aviation Safety Authority (CASA), acting as the delegate of the Commonwealth of Australia, issued this Airworthiness Directive (AD) to correct unsafe conditions identified in Boeing 767 Series Aeroplanes equipped with Pratt & Whitney Model PW 4000 series engines. The directive aims to mitigate risks associated with reduced acceleration and climb performance caused by fan thrust deterioration, ensuring that aircraft performance data remains accurate and reliable. This legislative instrument is designed to provide clear instructions and compliance timelines to operators, thereby safeguarding both crew and passengers.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA) under the legislative instrument F2006B03318. This particular Airworthiness Directive, AD/B767/141, applies to Boeing Model 767-200 and 767-300 series aeroplanes equipped with Pratt & Whitney Model PW 4000 series engines. The directive mandates the revision of the Aircraft Flight Manual (AFM) to include specific performance adjustments for engines with early production fan blades, addressing the issue of Fan Thrust Deterioration Mode (FTDM) that can lead to reduced acceleration and climb performance. The requirement must be met within 30 days of the directive's effective date, which is 12 July 2001, unless completed earlier. The directive was revoked and reissued to correct the FAA AD referred, ensuring safety measures are up-to-date and compliant with relevant standards. The directive is applicable across the Commonwealth of Australia and is notified in the Commonwealth of Australia Gazette on 27 June 2001.
Key Provisions
The Civil Aviation Regulations 1998, specifically under PART 39 - 105 and the Civil Aviation Safety Authority Schedule of Airworthiness Directives, contain a directive aimed at ensuring the airworthiness of certain Boeing 767 series aeroplanes. This directive, identified as AD/B767/141 Amendment 1, addresses the issue of reduced acceleration and climb performance in Boeing Model 767-200 and 767-300 series aeroplanes equipped with Pratt & Whitney Model PW 4000 series engines (section 1). The directive requires that the Aircraft Flight Manual (AFM) be revised to incorporate specific performance adjustments for engines with FB2B or FB2T fans installed. This adjustment is necessary to correct for the Fan Thrust Deterioration Mode (FTDM), which can lead to reduced thrust, runway overruns, or collisions with obstacles or terrain (section 2).
The obligations imposed by this Airworthiness Directive are clear and specific. Operators of the affected Boeing 767 series aeroplanes must ensure that their AFM is updated with the performance adjustments detailed in FAA Airworthiness Directive (AD) 2001-01-10 and its attachments, as referenced in Boeing Telex M-7200-00-02672 (section 3). This update must be incorporated as a general revision of the AFM, and once the information has been integrated, the FAA AD and the telex with its attachments must be removed from the AFM (section 4). Compliance with this directive must be achieved within 30 days from the effective date of the directive, which is 12 July 2001 (section 5).
Failure to comply with the requirements of this Airworthiness Directive could result in significant consequences. The Civil Aviation Regulations 1998 do not explicitly state the penalties for non-compliance with Airworthiness Directives, but non-compliance can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). Such actions may include fines, suspension or revocation of air operator certificates, or other regulatory measures deemed necessary to ensure compliance with aviation safety standards. The exact penalties would depend on the severity and nature of the non-compliance.
