## Abstract

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER (Model 737 NG) series airplanes (although the scope of the AD requirements is limited to operation at specific runways in the U.S., Colombia, and Guyana). This AD requires revising the airplane flight manual (AFM) to prohibit selection of certain runways for airplanes equipped with certain software. This AD was prompted by reports of display electronic unit (DEU) software errors on airplanes with a selected instrument approach to a specific runway. The FAA is issuing this AD to address the unsafe condition on these products.
