Abstract
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by a report that certain split ball bearings used in main landing gear (MLG) side brace actuator assemblies are manufactured from material that does not meet the required material properties. This AD requires an inspection of the left and right MLG side brace actuator assemblies and, if necessary, replacement of the split ball bearings. We are issuing this AD to address the unsafe condition on these products.
