Airworthiness Directives; Bombardier, Inc., Airplanes

Abstract

The FAA proposes to adopt a new airworthiness directive (AD) for all Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This proposed AD was prompted by an in-flight uncommanded, unarrested flaps movement accompanied by a FLAPS FAIL caution message. This proposed AD would require revising the existing aircraft flight manual (AFM) to provide the flightcrew with procedures to follow in the event of an uncommanded, unarrested flap movement. The FAA is proposing this AD to address the unsafe condition on these products.
