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.

Pursuant to CAR 202.51 the registered owner of a Canadian aircraft shall, within seven days, notify the Minister in writing of any change of his or her name or address.

CF-2013-37

Issue Date 

 28 November 2013 

Number: CF-2013-37 

Subject: Aft Baggage Bay Door – Non-Conforming Stop Fittings and Striker Plates 

Effective: 12 December 2013 

Applicability: Bombardier Inc.: 

Model CL-600-2C10 aeroplanes, serial numbers 10303 through 10333; 

Model CL-600-2D24 aeroplanes, serial numbers 15257 through 15284; 

Model CL-600-2E25 aeroplanes, serial numbers 19011 through 19024. 

Compliance: As indicated below, unless already accomplished. 

Background: During the manufacturing process, it was found that certain aft baggage bay door stop 

fittings and striker plates did not conform to the design specifications due to a quality 

control problem. This quality escape could degrade the strength of the affected aft 

baggage bay door stop fittings and striker plates. Failure of the aft baggage bay door 

stop fittings or striker plates may result in the opening of the aft baggage bay door and 

consequent rapid decompression of the aeroplane during flight. 

This AD mandates the initial and repetitive inspections of each aft baggage bay door stop

fitting and striker plate until the terminating action is accomplished. 

Corrective
