Abstract
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by a determination that a certain task in the aircraft maintenance manual (AMM) will not accomplish the intent of a candidate certification maintenance requirement (CCMR) for detecting dormant failures of the pitch feel (PF) and rudder travel limiter actuator (RTLA) back-up modules. This AD requires doing an operational test of the flight control unit (FCU) back-up modules, and repair if necessary. We are issuing this AD to address the unsafe condition on these products.
