Pilatus Correcting PC-12 Pitch Problem

A new pitch actuator will be required in some 330 U.S.-registered Pilatus PC-12s if the FAA adopts a proposed AD. The directive will require certain flap and autopilot limitations until the new actuator is installed. Pilatus reports the new actuator, which removes the flap-in-motion signal to the autopilot, is designed to prevent an abrupt nose-down pitch when the autopilot is disengaged while the flaps are at a 40-degree setting.
