2. PLANNING INFORMATION

NOTES: 1. To minimize aircraft downtime and cost, it is recommended to do

 Service Bulletin 601-0631, in conjunction with PART B of this Service

Bulletin.

2. This Service Bulletin is mandated by Airworthiness Directive (AD)

CF-2013-39R1.

A. Effectivity

CL-600-2A12 aircraft, Serial No. 3001 to 3066.

CL-600-2B16 aircraft, Serial No. 5001 to 5194.

NOTE: The instructions given in this Alert Service Bulletin are only applicable

to the systems and parts installed at the time of delivery of the aircraft

or as changed by Bombardier Aerospace Alert 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

On a Challenger 605 zonal inspection, one of the two forward fasteners

attaching the inboard flap hinge box forward hinge fitting at Wing Station (WS)

76.50 was found with its head missing.

The investigation shows that when installed with their head outside, those

fasteners will experience premature failure caused by higher pre-load due to

clamping and alignment.

This Alert Service Bulletin provides instructions to inspect and repair the

forward fasteners attaching the forward fittings at WS 76.50 and WS 127.25

at both wings.

C. Description

This Alert Service Bulletin gives instructions in:

PART A, to:

– Do the inspection of the forward inboard flap fasteners on the hinge box wing

forward fitting.

PART B, to:

– Remove the forward and aft inboard flap hinge-fairings,

– Remove the applicable upper and lower access panels,

– Do the inboard flap fasteners modifications as per APPENDIX 1 on the hinge

box wing forward fittings,

– Install the removed wing upper and lower access panels, and

– Re-install the forward and aft inboard flap hinge-fairings.

Bulletin release date (Revision 02).

NOTES: 1. At any time, if any of the forward fasteners heads are found

missing, PART B must be implemented before further flight.
