AIRWORTHINESS DIRECTIVE

The following airworthiness directive (AD) may be applicable to an aircraft which our records indicate is registered in your name. ADs are issued pursuant to Canadian 

Aviation Regulation (CAR) 521 Division X. Pursuant to CAR 605.84 and the further details of CAR Standard 625, Appendix H, the continuing airworthiness of a Canadian 

registered aircraft is contingent upon compliance with all applicable ADs. Failure to comply with the requirements of an AD may invalidate the flight authorization of the aircraft. Alternative means of compliance shall be applied for in accordance with CAR 605.84 and the above-referenced Standard.

This AD has been issued by the Continuing Airworthiness Division (AARDG), National Aircraft Certification Branch, Transport Canada, Ottawa, telephone 613 952-4357.

1/1 No.

CF-2014-17

Issue Date

17 June 2014

Number: CF-2014-17

ATA: 28, 33 Type Certificate: A-131

Subject: Additional limitation for landing/taxi light operations on ground due to potential fuel 

leakage

Effective Date: 17 June 2014

Applicability: Bombardier Inc. model CL-600-2B16 (604 Variant) aeroplanes, serial numbers 5301 

through 5665, and 5701 and subsequent.

Compliance: Within 24 hours from the effective date of this AD, unless already accomplished.

Background: Bombardier Inc. has determined that there is a potential for fuel leakage from the auxiliary 

power unit (APU) boost pump component installations in the right hand landing lights 

compartment. On a hot day, the temperatures in the landing light compartment as result of the 

heat generated by the taxi lights and/or the landing lights on the ground, can reach the 

auto-ignition temperature of the fuel and may ignite any fuel/fumes present in the right hand 

landing light compartment.

In order to mitigate the potential safety hazard, Bombardier Inc. has revised the Aircraft Flight 

Manual (AFM) through Temporary Revisions (TRs) 604/38 and 605/20 to introduce additional 

limitations for operation of the landing/taxi lights on the ground.

This AD is being issued to mandate compliance with the revised AFM limits for landing/taxi 

light operations per the TR 604/38 and TR 605/20, as applicable for the affected aeroplanes.

Corrective 

Actions:

Amend the AFM for:

A. Model CL-600-2B16 (604 Variant) aeroplanes, serial numbers 5301 through 5665, by 

incorporating the procedural changes introduced through TR 604/38 dated 16 June 2014,

or later revisions of these procedures as approved by Transport Canada. and

B. Model CL-600-2B16 (604 Variant) aeroplanes, serial numbers 5701 and subsequent, by 

incorporating the procedural changes introduced through TR 605/20 dated 16 June 2014,

or later revisions of these procedures as approved by Transport Canada..

Advise all concerned personnel of the above listed procedural changes.
