## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Raytheon Aircraft Corporation (Raytheon) Models 1900C, 1900D, and 2000 airplanes. The proposed action would require inspecting (one-time) the fuel filter assemblies to detect any bypass valve that is glued shut. If a bypass valve is glued shut, the proposal would require replacing the associated fuel filter assembly. Three in-flight occurrences where the low fuel pressure light illuminated prompted the proposed action. In each of the instances, a bypass valve on the affected engine was glued shut with anaerobic thread lock adhesive and when the fuel filter became clogged, proper fuel flow to the engine was not obtained. The actions specified by the proposed AD are intended to prevent lack of fuel to the engine and eventual engine shutdown caused by a clogged fuel filter and a contaminated fuel filter by-pass valve.
