Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This proposed AD was prompted by a report of an in-flight event where a flightcrew observed a SPOILER FAIL message and had difficulty maintaining roll control of the airplane. This proposed AD would require revising the existing airplane flight manual (AFM) to provide the flightcrew with procedures related to roll spoiler failures that reduce the flightcrew workload during this type of failure scenario. The FAA is proposing this AD to address the unsafe condition on these products.
