Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
Abstract
The FAA is adopting a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2C10 (Regional Jet Series 700, 701 & 702); CL-600-2C11 (Regional Jet Series 550); CL-600-2D15 (Regional Jet Series 705); and CL-600-2D24 (Regional Jet Series 900) airplanes. This AD was prompted by a determination that a potential crack of the tombstone fitting lug cannot be detected as the bushings remain in place during accomplishment of the special detailed inspection (SDI) required by a certain airworthiness limitation (ALI) task. This AD requires inspecting the tombstone fitting lug with a new SDI sub-surface ultrasound procedure when accomplishing the ALI task, as specified in a Transport Canada AD, which is incorporated by reference. This AD also requires corrective actions if necessary. The FAA is issuing 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.
