### 1. PLANNING INFORMATION
NOTES : 1. To minimize aircraft downtime and cost, it is recommended to do Service Bulletin 605-57-005, PART A , in conjunction with PART B of this Service Bulletin. 2. This Service Bulletin is mandated by emergency Airworthiness Directive (AD) CF-2014-27R1 and FAA AD 2014-17-51. A. Effectivity CL-600-2B16 aircraft, Serial No. 5701 to 5920

. The intent of this Service Bulletin PART B was met on the aircraft that follow with the Repair Engineering Orders (REO) and Service Requests for Product Support Action (SRPSA) listed in the table that follows:

AIRCRAFT SERIAL NO. DRAWING. SRPSA NO.
5783 REO 600-57-26-001 31364
5818 REO 600-57-26-001 31385
5862 REO 600-57-26-001 32285 A repair was carried out on the Right Side at WS 76.50 for aircraft, Serial No. 5725 with the REO 604-57-26-005 and SRPSA 30876. , Perform this Service Bulletin only to the remaining 3 forward fittings, to m eet the intent of this Service Bulletin. Aircraft, Serial No. 5921 and all other subsequent aircraft were scheduled for the modification in production (Ref.: Restriction and/or Special Instruction (RSI), C-4095). NOTE : The instructions given in this Alert Service Bulletin are only applicable to the systems and parts installed at t he 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 fi tting at Wing Station (WS) 76.50 was found with its head missing. The investigation shows that when in stalled with their head outside, those fasteners will experience premature failu re caused by higher pre-load due to clamping and alignment. This Alert Service Bulletin provides inst ruction to inspect and repair the forward fasteners attaching the forward fittings at WS 76.50 and WS 127.25 at both wings.MODEL CL-600-2B16
