Service Bulletin CK-SB002 Released

[v.schmidt]

Service Bulletin 002 applies to the Carbon Cub EX models S/N CCK-1320-001, and CCK1865-0001-0090. CK-SB002 relates to the fuel system installed on these airframes.

Cub Crafters, Inc. has determined that there is potential for a low spot to form in the left aft fuel line where condensation could collect below the rear corner of the left side window. This service bulletin provides instructions for retrofitting aircraft to include an additional fuel drain to avoid the potential of water collecting in the line.

Compliance with Part A is required prior to next flight and until Part B is complied with. Part B compliance is recommended at next 100 hour inspection. Continued inspections are required at each annual condition inspection.

If you have any questions, please contact Cub Crafters Customer Support at (509) 248-9491 or support@cubcrafters.com.

As a new Forum user I cannot find information here that describes in the context of this fuel flow problem, what Part A or Part B compliance is. No doubt this information exists but where is it and how do I find it ??

Thanks Steve Y, it is now clear.
I should have tried a bit harder or perhaps more broadly.
What now puzzles me now is that after reviewing SB002, I discover that I have already piped my system as per this mod.
I completed this about 14 months ago following instructions and a kit from CubCrafters.
Seems like SB002 is a little late/slow.
