Important Global Flap Spigot Bushing Service Bulletin

November 2017

Bombardier just released the following SBs (Service Bulletins) on October 18, 2017, calling for the inspection and replacement of the inner flap spigot bushing on all current Global* aircraft. Production cut in at serial number 9758.

After a detailed investigation, it was discovered the spigot tube bushing could migrate from its original position causing damage to bolts and wear on the spigot tube. This SB replaces the spigot bushing with one that will not migrate from its position after it is installed and that will prevent damage.

To allow adequate time to perform this SB, Bombardier highly recommends it by a part of the next 60 or 120 month inspection and complied within 60 months of the Rev 01 release date.

Please note that if corrosion is found during the course of complying with the spigot SB, there are restricted limitations on the ribs, which could result in their replacement.  Replacement would require the removal of flap skins and follow-up paintwork.
