What Are These Service Bulletins For?
Bombardier has issued a series of Services Bulletins in regard to I/B, Mid & O/B flap assemblies that recommend inspection and modification of flaps for corrosion & drainage issues.
Bombardier has issued a series of Services Bulletins in regard to I/B, Mid & O/B flap assemblies that recommend inspection and modification of flaps for corrosion & drainage issues.
We inspect inside of the flap with a borescope through the drain holes in the lower surface. If no corrosion is noted you clean and spray corrosion preventive compound to better protect the areas. We then add additional drain holes to the lower flap surfaces to help with the removal of moisture. If corrosion is noted the flap will then be removed from the A/C, and skins removed from the flap to access the corrosion. The corrosion is removed, measured, and reported to engineering for disposition. The inner areas of the flap are then treated with corrosion preventive compounds to better protect the aluminum components inside the flap. Sealant is also added to some key areas for better protection. The flap is then reassembled, painted, and installed on the A/C.
These Service Bulletins are not mandatory at this time, but are recommended that they be addressed at the next scheduled maintenance event. When scheduled in conjunction with the 120 or 240-month inspections, these service bulletins don’t increase downtime. However, if scheduled during the 60-month or 180-month inspection, down time may be increased slightly if full access is required due to corrosion inside the flaps.
These Service Bulletins can be addressed at both the Grand Junction, CO (GJT) and East Alton, IL (ALN) West Star Aviation facilities.
