## Summary

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This proposed 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 proposed AD would require installing a restrictor into the engine fuel feed line. We are proposing this AD to prevent blocked engine fuel flow and possible engine flameout.
