St. Louis, Mo. 11 Aug. 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.
The Challenger 600 series is a family of business jets produced by Bombardier. They feature a range of 3,875 miles and a cruise speed of 521 miles per hour. The aircraft were designed in 1976, with a prototype taking flight in 1978. The design was certified in 1980 by both Transport Canada and the Federal Aviation Administration.
Jet Aviation St. Louis has repaired three Challengers in compliance with the service bulletin with the help of its newly acquired Cold Jet Aero 40 HP dry ice blasting machine. Specially trained technicians use the machine to remove the epoxy without damaging the existing door structure.
