Airworthiness Directives; Bombardier, Inc., Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-2A12 airplanes. This AD was prompted by a report of a lateral offset observed on the head-up display (HUD) of several airplanes between the synthetic vision system (SVS) and actual runway due to mechanical misalignment of the HUD during manufacturing and assembly. This AD requires revising the existing airplane flight manual (AFM) to prohibit steep approach landing (SAL) and enhanced flight vision system (EFVS) operations. This AD also requires calibrating the HUD. The FAA is issuing this AD to address the unsafe condition on these products.
