## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model EMB-135BJ series airplanes. This proposed AD would require modifying the electrical wiring for the "stick pusher" system. This proposed 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 proposing this AD to prevent reduced controllability of the airplane if the stick pusher system malfunctions.
