## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model EMB-135BJ series airplanes. This AD requires modifying the electrical wiring for the "stick pusher" system. This AD is prompted by a report that the stick pushers are not being inhibited when the AP/PUSH/TRIM switches are activated, which can result in reduced controllability of the airplane if there is a system malfunction. We are issuing this AD to prevent reduced controllability of the airplane if the stick pusher system malfunctions.
