Biz AV's AD Watch

The FAA is proposing the adoption of a new airworthiness directive (AD) that is applicable to certain Raytheon Model Beech 400A and 400T series airplanes. This rule 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. The FAA claims 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. Comments must be received by December 19, 2003.
