Abstract
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD requires modifying the bleed-air duct and detection system; and revising the maintenance or inspection program, as applicable. This AD was prompted by a report of a possibility that the shrouds of the high pressure bleed air ducts could deteriorate and their maximum permitted leakage rate could be exceeded. We are issuing this AD to address the unsafe condition on these products.
