## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Raytheon Model Beech 400A and 400T series airplanes. This proposal would require an inspection to determine the part number of the A194 roll trim printed circuit board (PCB), and replacement of certain PCBs with improved parts. This action is necessary to prevent intermittent sticking of the relays on the PCB in either the open or closed position, which could result in an out-of-trim condition that could require using considerable control wheel force to keep the wings level, and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
