This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 97-14-11 that was sent previously to all known U.S. owners and operators of certain Bombardier Model CL- 600-2B19 (Regional Jet Series 100 and 200) series airplanes by individual notices. This AD requires repetitive inspections to detect cracks of a certain bulkhead web of the fuselage at certain locations, and repair, if necessary. This action is prompted by a report of a pressurization problem during flight, which was caused by fatigue cracking in the underfloor pressure bulkhead of the fuselage. The actions specified by this AD are intended to detect and correct such fatigue cracking, which could result in uncontrolled depressurization of the airplane and/or reduced structural integrity of the fuselage.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
