Summary
We propose to adopt a new airworthiness directive (AD) for all Saab AB, Saab Aeronautics Model SAAB 2000 airplanes. This proposed AD was prompted by an event where the airplane did not respond to the flightcrew's flight control inputs because the pitch trim switches did not disconnect the autopilot. This proposed AD would require modifying the wiring installation for the autopilot disconnect logic. We are proposing this AD to address the unsafe condition on these products.
