COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Bombardier (Canadair) CL-600 (Challenger) Series Aeroplanes
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/CL-600/34 Amdt 1 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.
Applicability: Model CL-600-2B19 “Regional Jet” aircraft, serial numbers 7003 and subsequent.
Requirement: Accomplish the requirements of Transport Canada (TC) AD CF-1998-14R3 by accomplishing the parts specified in either (i) or (ii) below:
(i) Part I, Part II, and Part III (sections A and B); or,
(ii) Part III (section A only) and Part IV.
The flight manual amendments required by sections A, B, and C of Part I of TC AD CF-1998-14R3 may be accomplished by inserting a copy of TC AD CF-98-14R3 in each of the affected sections of the Aircraft Flight Manual.
Note: Accomplishment of Part IV of TC AD CF-98-14R3 constitutes terminating action for Parts I, II, and III.B of the Requirement document.
Compliance: Part I of the Requirement document: Before 9 August 2000, unless already accomplished.
Part II of the Requirement document: As specified in the Requirement document.
Part III of the Requirement document: Within 450 hours time in service after 3 November 1999, unless already accomplished.
Part IV of the Requirement document: As specified in the Requirement document. The compliance times remain unchanged by this amendment.
This Amendment becomes effective on 1 November 2001.
Background: Transport Canada received reports of a number of cases of flap system failure which resulted in a twisted outboard flap panel. These failures were caused by an internal fault within the No. 3 flap actuator (inboard actuator on the outboard flap). In one case a twisted flap was not detected prior to take-off, while in two other cases flap deployment occurred on deployment of the flaps for landing. In all cases the aircraft was controllable and landed successfully.

AD/CL-600/34 Amdt 2 (Continued)
Amendment 1 provided terminating action for Parts I, II, and III.B of the AD.
Amendment 2 is issued in response to a revision of the Requirement document which revises Part III.A. by listing additional service bulletins that provide approved instructions for the installation of new airspeed placards, and to mandate incorporation of Temporary Revision RJ/71 which reflects the airspeed limitation placard in the aircraft into the Aircraft Flight Manual.
Amendment 1 of this Airworthiness Directive became effective on 2 August 2000.
The original issue of this Airworthiness Directive became effective on 3 November 1999.

The above AD is notified in the Commonwealth of Australia Gazette on 10 October 2001.
Overview
The Civil Aviation Regulations 1998, enacted by the Australian Parliament, are comprehensive regulations governing civil aviation operations within Australia. These regulations aim to ensure the safety and efficiency of civil aviation in the country. One specific area addressed by these regulations is the issuance of Airworthiness Directives (ADs) to maintain the airworthiness of aircraft. The AD in question, AD/CL-600/34 Amdt 2, pertains to the Bombardier (Canadair) CL-600 (Challenger) Series Aeroplanes and was introduced to address safety issues identified in the flap system of certain aircraft models. This AD mandates specific actions to correct unsafe conditions that could potentially lead to flap system failures, ensuring the continued safety of these aircraft in operation. The Civil Aviation Safety Authority (CASA) is responsible for issuing such directives, aiming to maintain high safety standards in the aviation sector.
Scope and Application
This Airworthiness Directive (AD) under the Civil Aviation Regulations 1998 pertains specifically to the Bombardier (Canadair) CL-600 (Challenger) Series aeroplanes, more specifically to model CL-600-2B19 "Regional Jet" aircraft with serial numbers 7003 and subsequent. Issued by the Civil Aviation Safety Authority (CASA) delegate, the AD mandates compliance with Transport Canada Airworthiness Directive CF-1998-14R3 to address reported cases of flap system failure. This failure, caused by an internal fault within the No. 3 flap actuator, led to a twisted outboard flap panel, posing a safety risk. The AD outlines the specific parts of the Transport Canada directive that must be followed, including mandatory amendments to the Aircraft Flight Manual. The compliance timelines set by the AD are stringent, with certain actions required before specific dates or within certain timeframes post-service hours. This AD is applicable across the Commonwealth of Australia and is enforced to ensure the ongoing airworthiness of the specified aircraft models, directly impacting the aviation industry and entities operating these aircraft.
Key Provisions
The Civil Aviation Regulations 1998, under Part 39, specify Airworthiness Directives (AD) that must be followed for the safe operation of certain aircraft. Specifically, AD/CL-600/34 Amdt 2 concerns Bombardier (Canadair) CL-600 (Challenger) Series Aeroplanes, particularly the Model CL-600-2B19 “Regional Jet” aircraft with serial numbers 7003 and subsequent. The AD requires the completion of Transport Canada (TC) AD CF-1998-14R3, which outlines specific actions to correct unsafe conditions related to the flap system and airspeed placards. The requirements mandate either the accomplishment of Parts I, II, and Part III (sections A and B) or Part III (section A only) and Part IV of the TC AD. Compliance with these requirements must be achieved by specific deadlines, with some parts needing to be completed before 9 August 2000 and others within 450 hours of time in service after 3 November 1999.
The obligations under this AD fall primarily on the aircraft operators and owners. They must ensure that the specified actions are taken in accordance with the instructions outlined in the AD. This includes the amendment of the Aircraft Flight Manual as required by the TC AD, with specific parts of the manual needing to be updated to reflect the necessary changes. Additionally, operators must adhere to the compliance timelines set out in the AD, ensuring that the required actions are completed within the stipulated periods.
Failure to comply with the provisions of this AD may result in significant consequences. Non-compliance can lead to the aircraft being deemed unairworthy, which could prevent it from operating until the required actions are completed. The AD does not specify exact penalties, but non-compliance could potentially lead to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions might include fines, grounding of the aircraft, or other regulatory measures to ensure that the safety directives are followed. The severity of the penalties would depend on the extent and nature of the non-compliance.
