This Airworthiness Directive (AD) is issued pursuant to Canadian Aviation Regulation (CAR) 521.427.
No person shall conduct a take-off or permit a take-off to be conducted in an aircraft that is in their legal
custody and control, unless the requirements of CAR 605.84 pertaining to ADs are met. Standard 625 -
Aircraft Equipment and Maintenance Standards Appendix H provides information concerning alternative
means of compliance (AMOC) with ADs.
Number: Effective Date:
CF-2020-53 21 December 2020
ATA: Type Certificate:
05 A-276
Subject:
Time Limits / Maintenance Checks – Maintenance Program
Applicability:
MHI RJ Aviation ULC. (formerly Bombardier Inc.) aeroplanes:
Model CL-600-2C10 and CL-600-2C11, serial numbers 10002 and subsequent,
Model CL-600-2D15 and CL-600-2D24, serial numbers 15001 and subsequent,
Model CL-600-2E25, serial numbers 19001 and subsequent.
Compliance:
As indicated below, unless already accomplished.
Background:
The airworthiness limitations (AWLs) and safe life components for the CL-600-2C10, CL-600-2C11,
CL-600-2D15, CL-600-2D24 and CL-600-2E25 aeroplanes are defined and published in Part 2 of the
Customer Support Publication (CSP) B-053 Maintenance Requirements Manual (MRM), approved by
Transport Canada. The instructions contained in the MRM Part 2 have been identified as mandatory
actions for continued airworthiness. During revision updates of the MRM, some tasks in Part 2, Section 2
(Structural Inspections) and Section 3 (Safe Life Components) that were added, deleted and/or revised
may not have been incorporated into the operator’s approved maintenance schedule. Failure to comply
with these instructions could result in an unsafe condition.
In order to assist the operators with the incorporation of all the mandatory maintenance/inspections tasks
and replacement of life limited parts, MHI RJ Aviation ULC. (MHIRJ) has released service bulletin (SB)
670BA-05-001. This SB provides a list of the mandatory requirements, as published in Section 2 and
Section 3 of MRM Revision 23 and subsequent revisions that must be complied with by all operators.
This AD requires the incorporation of the mandatory requirements listed in SB 670BA-05-001 into the
operator’s approved maintenance schedule.
Corrective Actions:
A. Within 180 days from the effective date of this AD, revise the operator’s approved maintenance
schedule to incorporate the new or revised instructions listed in SB 670BA-05-001, dated 27 August
2020, or later revisions approved by the Chief, Continuing Airworthiness, Transport Canada, as
applicable to the aeroplane model and configuration.
B. The maintenance/inspection tasks and/or life limited parts replacement as listed in Figure 1 and
Figure 2 of SB 670BA-05-001 must be accomplished before the aeroplane reaches the new/revised
thresholds and/or intervals as provided in MRM Revision 23 or subsequent revisions for each item. If
there is a difference between the tasks listed in Figure 1 and Figure 2 of SB 670BA-05-001 and the
Part 2 of MRM Revision 23 (CSP B-053) or subsequent revisions at the time of compliance with this
AD, MRM Part 2 content must be followed.

NOTE: The instructions in this service bulletin are only applicable to the
systems and parts installed at the time of delivery of the aircraft or as
changed by MHIRJ service bulletins. Before you do this service
bulletin, examine all Supplemental Type Certificates (STCs) and
Supplemental Type Approvals (STAs) or equivalent action changes
to make sure you can complete this service bulletin.

B. Reason

(1) Condition

During subsequent revision updates of the aircraft maintenance requirements

manual (MRM), some tasks in the Part 2 Airworthiness Limitations (ALIs),
Section 2 (Structural Inspections) and Section 3 (Safe Life Components) that
were added, deleted and/or revised may not have been incorporated in the
operators approved maintenance program. Changes that were not
incorporated into the approved maintenance program may result in an unsafe
condition in the operation of the aircraft. MRM Revision 23 or subsequent
gives the mandatory instructions and airworthiness limitations.

(2) Evidence

Conclusions of an internal review of Airworthiness Limitations (ALIs) for

Principal Structural Elements (PSEs).

(3) Objective/Benefit

This service bulletin gives the procedures and a list to make sure that the
operators approved maintenance program is as per the Revision 23 or
subsequent of the MRM Part 2 (ALIs), Section 2 (Structural Inspections) and
Section 3 (Safe Life Components). This will make sure that all the
Airworthiness Limitations (AWLs) published in the MRM Part 2 Revision 23 or
subsequent are taken into account by all operators.

C. Description

All applicable inspection tasks listed in Figure 1 (MRM PART 2 Airworthiness

Limitation Items (ALIs) − Section 2 Structural Inspections) and all Safe lives listed
in Figure 2 (MRM PART 2 Airworthiness Limitation Items (ALIs) − Section 3 Safe
Life Components) of this service bulletin must be incorporated into the operators
approved maintenance program. Figure 1 and Figure 2 are copied from the CRJ
Series 550/700/705/900/1000 MRM Revision 23, Part 2, Sections 2 and 3 as
reference. If there is a difference between the figures and the MRM Part 2 revision
23 or subsequent, MRM Part 2 content must be follow.
