Summary

We propose to adopt a new airworthiness directive (AD) for all Bombardier, Inc., Model CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This proposed AD was prompted by a report that main landing gear (MLG) side stay actuators have been assembled using nonconforming split ball bearings. This proposed AD would require verification of the serial numbers of the installed MLG side stay actuator assemblies, and replacement of the affected parts. We are proposing this AD to address the unsafe condition on these products.

The agency’s own summary, as published.
