Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes

FAA / Federal Register · 2020-21882

The FAA proposes to adopt a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD was prompted by evidence that a revised structural life limit of some components of the nose landing gear (NLG) and/or main landing gear (MLG) was not implemented during repair. This proposed AD would require verifying that the affected components are installed on the airplane, revising the structural life limits in the structural deviation inspection requirements (SDIR) airplane document, and replacing affected components if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
