Years have passed since Bombardier issued Global* Flap Corrosion Protection and Drainage Improvement SBs (Service Bulletins) inner, mid, and outboard flap assemblies, which call for the inspection and modification of flaps for corrosion and drainage issues.
An internal borescope inspection of the flaps is performed through drain holes. If no corrosion is found, the area is clean, and a preventive compound is applied. Additional drain holes are added for the removal of moisture.
If corrosion is found during the course of these SBs, the flaps are removed to access the corrosion and follow-up paintwork.
These are recommended Service Bulletins we are ready to accommodate as part of your next major calendar inspection.
