REWORK OF THE DCPC COVERS 

1. PLANNING INFORMATION 

NOTES: 1. To reduce aircraft downtime, it is suggested to incorporate this 

Service Bulletin with the Service Bulletins that follow, if applicable: 

SB 100-24-12 

SB 100-24-15 

SB 100-24-17 

SB 100-24-18 

SB 100-24-20 

SB 100-24-19 

SB 100-24-22 

2. This Service Bulletin is also applicable to the DCPCs in the operator’s 

stock room. 

3. This Service Bulletin is currently being offered as part of the Challenger 

300 MAX Program. 

 Bombardier recommends that this modification be incorporated at your 

next convenient downtime. 

 Bombardier recommends contacting your In-Service Implementation 

Team (ISIT) representative as soon as is practical to schedule your 

aircraft at the following email address: 

CL300_MAX@aero.bombardier.com.

A. Effectivity 

BD-100-1A10 aircraft, Serial No. 20003 to 20405. 

NOTES: 1. All other subsequent BD-100-1A10 aircraft are scheduled for 

the modification in production (Ref.: Modification Summary 

100T010680). 

2. 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 Bombardier Service Bulletin(s). 

Before you do this bulletin, examine all STC, STA or equivalent 

action changes to make sure that this bulletin can be completed. 

B. Reason 

The flexibility of the existing front covers of the left DCPC, right DCPC and 

auxiliary DCPC does not guarantee that the printed circuit boards (PCBs) are 

correctly inserted in the motherboard. If a PCB is not installed fully in the 

motherboard, it can possibly stay in that condition after the cover is installed. 

This can cause loss of communication and functional defects. 

This Service Bulletin reworks the covers to a re-enforced design which prevents 

deflection. 

C. Description 

This Service Bulletin gives instructions to: 

– Get access to DCPCs, 

– Do the Zodiac Aerospace Service Bulletin No. 975GC02Y-24-013, for the 

LH DCPC, 

– Do the Zodiac Aerospace Service Bulletin No. 970GC02Y-24-013, for the 

RH DCPC, 

– Do the Zodiac Aerospace Service Bulletin No. 320GC03Y-24-012, for the 

auxiliary DCPC 

D. Compliance 

Recommended within 800 flight hours from this Service Bulletin release date 

(Basic Issue). 

E. Approval 

The technical content of this Service Bulletin has been approved under 

the authority of Transport Canada Civil Aviation (TCCA) Design Approval 

Organization (DAO) No. DAO #93-Q-02. 

NOTES: 1. The technical content of this Service Bulletin is accepted by the
