AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/CL-600/58 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.
Bombardier (Canadair) CL-600 (Challenger) Series Aeroplanes
AD/CL-600/58
Amdt 1
Aileron Stiffness 10/2002 DM
Applicability: All CL-600-2B19 aircraft.
Requirement: 1. Amend the Aircraft Flight Manual (AFM) by inserting Temporary Revision (TR) RJ/109-2 dated 9 August 2002. TR RJ/109-2 introduces the following:
- An amendment to Emergency Procedures for aileron system jams. This change is applicable to all aircraft.
b. An aileron control check procedure to the Limitations Section. This change is applicable to aircraft that have accumulated 5,000 total flight hours.
2. Insert a copy of this Directive in each AFM.
3. Advise all flight crews on the changes introduced through the AFM TR.
Note: Transport Canada AD CF-2002-35R1 refers.
Compliance: Within 14 days after 28 August 2002, unless already accomplished.
This amend ment becomes effective on 28 August 2002.
Background: A significant number of reports of aileron control stiffness have been received following climb to altitude after takeoff from a contaminated runway or during heavy rain. In every case, the aileron stiffness disappeared upon descent to lower altitude and the aircraft landed safely. The aircraft that have encountered aileron control stiffness had accumulated in excess of 5,000 total flight hours when the problem appeared.

AD/CL-600/58 Amdt 1 (continued)
Amendment 1 is issued in response to a revision of the related Transport Canada AD which introduces an amended AFM TR which increases the minimum altitude for commencement of the aileron control checks.
The original issue of this Airworthiness Directive became effective on 7 August 2002.

The above AD is notified in the Commonwealth of Australia Gazette on 28 August 2002.
Overview
The Civil Aviation Safety Authority (CASA) issued Airworthiness Directive (AD) AD/CL-600/58 Amendment 1 on 21 August 2002 to address the issue of aileron stiffness in Bombardier (Canadair) CL-600 (Challenger) Series Aeroplanes. This AD was introduced in response to numerous reports of aileron control stiffness following climb to altitude after takeoff from a contaminated runway or during heavy rain. The directive was enacted under subregulation 39.1 (1) of the Civil Aviation Regulations 1998, with the objective of ensuring that the specified actions are taken to correct the unsafe condition. CASA revoked the previous AD/CL-600/58 and issued this amended directive to mandate the insertion of Temporary Revision (TR) RJ/109-2 dated 9 August 2002 into the Aircraft Flight Manual (AFM), introduce an aileron control check procedure to the Limitations Section for aircraft with accumulated 5,000 total flight hours, and ensure that all flight crews are informed of these changes. Compliance with this directive was required within 14 days after 28 August 2002.
Scope and Application
The Airworthiness Directive issued under the Civil Aviation Regulations 1998 pertains specifically to all Bombardier (Canadair) CL-600-2B19 aircraft, demanding adherence to stringent safety measures to address aileron stiffness issues that have arisen post-takeoff from contaminated runways or during heavy rain conditions. This AD requires the amendment of the Aircraft Flight Manual (AFM) to include a Temporary Revision (TR) dated 9 August 2002, introducing emergency procedures for aileron system jams and an aileron control check procedure applicable to aircraft that have accumulated 5,000 total flight hours. Additionally, the directive mandates the insertion of a copy of this AD in each AFM and the briefing of all flight crews on the introduced changes. This directive must be complied with within 14 days from 28 August 2002 unless already implemented, reflecting a coordinated response to the identified safety concerns in line with the related Transport Canada AD. The AD applies across the Commonwealth of Australia and is enforced through the Civil Aviation Safety Authority.
Key Provisions
The key operative sections of the Airworthiness Directive (AD) AD/CL-600/58 Amdt 1 require certain amendments to the Aircraft Flight Manual (AFM) for Bombardier (Canadair) CL-600 (Challenger) Series Aeroplanes. Specifically, Section 1(a) mandates that the AFM be amended by inserting Temporary Revision (TR) RJ/109-2 dated 9 August 2002. This amendment introduces changes to the Emergency Procedures for aileron system jams and adds an aileron control check procedure to the Limitations Section for aircraft that have accumulated 5,000 total flight hours. Section 1(b) requires a copy of this Directive to be inserted in each AFM, while Section 1(c) mandates that all flight crews be advised of the changes. Compliance with these requirements must be achieved within 14 days after 28 August 2002, unless already accomplished, as specified in Section 3.
The obligations imposed on the parties governed by this AD include ensuring that the specified changes are made to the AFM and that these changes are communicated to all relevant flight crews. Owners and operators of the affected aircraft must ensure that the AFM is updated with the new TR RJ/109-2, which includes the amended emergency procedures and the new aileron control check procedure. Additionally, they must ensure that a copy of the AD is inserted in the AFM and that all flight crews are briefed on the changes. Failure to comply with these obligations can result in serious safety implications, as the AD is issued to correct an unsafe condition identified with the aircraft.
Breach of the requirements set out in this AD may lead to civil or criminal consequences, although specific offences and penalties are not detailed in the AD itself. However, non-compliance with ADs generally can result in significant penalties under the Civil Aviation Act 1988 and the Civil Aviation Regulations 1988. These can include substantial fines and potential criminal charges for individuals and corporations found to be in breach. The severity of the penalties may depend on the circumstances of the non-compliance and the impact on air safety. It is important for operators to adhere strictly to the AD to avoid these potential consequences.
