Jet Aviation St. Louis is Repairing Challenger 600 Series Aircraft in Compliance with Bombardier Service Bulletin ATA 52-11

St. Louis, Mo. / August 9, 2012 – Jet Aviation St. Louis has acquired the necessary tools and training to comply with Bombardier’s Service Bulletin (SB) ATA 52-11, issued to address passenger door corrosion prevention, and has repaired thee aircraft to date: two Challenger 604s and one Challenger 605.

SB ATA 52-11 is a “special check/modification” of the passenger door that requires removing the epoxy used in door fabrication to prevent corrosion. The bulletin also calls for adding additional drainage holes and modifying the door structure to allow access to facilitate scheduled inspections.
