## Abstract

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This AD was prompted by reports of swing arm assemblies of engine fuel feed ejector pumps detaching from the outlet port of the engine fuel feed ejector pump and partially blocking the engine fuel feed line. This AD requires installing a restrictor into the engine fuel feed line. We are issuing this AD to prevent blocked engine fuel flow and possible engine flameout.
