Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., CL-600-2B16 (604 Variant) airplanes. This proposed AD was prompted by multiple reports of cracking of the main landing gear (MLG) shock strut lower pin. This proposed AD would require repetitive lubrication and repetitive detailed visual inspections (DVI) and non-destructive test (NDT) inspections of the MLG shock strut lower pins, and replacement if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
