Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes. This proposed AD was prompted by a report that the electrical harnesses in the overhead bin above the class divider may have insufficient or no separation with the class divider mounting plate. This proposed AD would require inspecting the overhead bin electrical harnesses at the class dividers, and modifying the class divider mounting plate assembly or accomplishing a temporary repair if necessary; and, eventually modifying the class divider mounting plate assembly if a modification was not done after accomplishing the inspection, as specified in a Transport Canada AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
Applicability
Aircraft makes and models this AD applies to, sorted by US-registered fleet size.
