Airworthiness Directives; Cessna Model 560 Airplanes

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Cessna Model 560 airplanes. This action requires disengaging and tie-strapping the pitch trim and autopilot servo (servo 1) circuit breakers. This action also provides an optional inspection and follow-on actions that, if accomplished, terminates the requirement to disengage and tie-strap those circuit breakers. This action is necessary to prevent a single-point failure in the trim system from causing a runaway trim condition that the pilot may be unable to stop by using the autopilot-disconnect switch. This condition could result in loss of control of the airplane. This action is intended to address the identified unsafe condition.
