1. PLANNING INFORMATION 

A. Effectivity 

CL-600-2B16 aircraft, Serial No. 5701 to 5918. 

The intent of Service Bulletin 605-34-027 (Revision 02) was met on the aircraft 

that follow VIA the incorporation of Service Bulletin 605-34-027 (Basic Issue) and 

the Service Non-Incorporated Engineering Orders (SNIEO) listed in the table that 

follows: 

AIRCRAFT SERIAL NO. Drawing 604-51027

The intent of Service Bulletin 605-34-027 (Revision 02) was met on the aircraft 

that follow VIA the incorporation of Service Bulletin 605-34-027 (Basic Issue) and 

the Report of Non Compliance (RNC) listed in the table that follows: 

AIRCRAFT SERIAL NO. RNC NO. 

5892 C312063687 

5893 C312055374

MODEL CL-600-2B16 

Basic Issue: Jul 31/2012 605-34-027

Revision 02: Dec 20/2012 Page 2 of 12 

All other subsequent CL-600-2B16 aircraft are scheduled for the modification 

in production (Ref.: Modification Summary 600-6258). 

NOTES: 1. If the Basic Issue was entered in the aircraft log book, Revision 02 

can be entered into the log book without doing any physical changes 

to the aircraft. 

 2. If the Basic Issue and SNIEO S01 was entered in the aircraft log 

book, you can enter Revision 02 into the log book without doing any 

physical changes to the aircraft. 

 3. If the Basic Issue and RNC’s listed above were entered into the 

aircraft log book, you can enter Revision 02 into the log book without 

doing any physical changes to the aircraft. 

4. 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 

There is a possibility, when flying into adverse weather conditions, of water 

ingress in the pitot and static lines. The presence of water in the pitot and static 

lines could restrict the air passage which can result in fluctuating and incorrect 

flight display data for airspeed and altitude indications. 

This Service Bulletin replaces the current drain bottle assemblies related to the 

pitot and static lines with an improved design and larger capacity drain bottles. 

Replacement of the drain bottle assemblies will reduce incorrect flight display data 

for airspeed or altitude. 

C. Description 

This Service Bulletin gives instructions to: 

– Get access to the cockpit under floor, 

– Remove the existing drain bottles and fittings, 

– Install the new drain bottles and fittings, and 

– Do the necessary tests to make sure that the system operates correctly. 

D. Compliance 

Recommended within 24 months from this Service Bulletin release date 

(Basic Issue). 

NOTE: This Service Bulletin is in reference to TCCA Airworthiness Directive, 

CF-2012-30.
