1 ELEVATOR AND PITCH TRIM SYSTEM 1. DESCRIPTION This section describes that portion of the flight control system which controls the position and movement of the elevator. Included are; elevator system torque tube, rigging, push/pull rods, pulleys, and pitch trim cartridge, and pitch relays. Serials 100 thru 100, 10 thru 10: Elevator control motion is transferred by the control yoke through a linkage to a pulley sector mounted on the elevator torque tube. From the pulley sector, control motion is passed to a single cable system which is routed through the forward pulley gang at the bottom of the center console, through to the rudder/elevator pulley gang under the baggage floor, and finally to the elevator actuation pulley. The elevator actuation pulley drives a push/pull rod attached to the elevator bellcrank which is bolted directly to the elevators. Each set of pulleys has a cable retainer to prevent fouling. Adjustable control stops at the elevator actuation pulley limit control surface travel. Serials 101, 107, & subs: Elevator control motion is transferred by the control yoke through a linkage to a bellcrank weldment on the elevator torque tube. From the bellcrank, control motion is transferred to a single cable system which is routed to the forward pulley gang at the bottom of the center console, through to the rudder/elevator pulley gang under the baggage floor, and finally to the elevator empennage bellcrank. The elevator empennage bellcrank drives a push/pull rod attached to the aft elevator bellcrank which is bolted directly to the elevators. Each set of pulleys has a cable retainer to prevent fouling. Fixed control stops at the elevator empennage bellcrank limit control surface travel. The pitch trim system employs a ground adjustable trim tab and a spring cartridge activated by an electric motor. The spring cartridge, directly connected to the elevator bellcrank and the electric trim motor, provides a centering force regardless of the direction of control surface deflection. When activated, the trim motor moves the spring cartridge causing the elevator bellcrank to move the elevator to a new trimmed position. A -way switch, mounted on both yoke grips, controls the pitch trim system. WARNING: A system rigging Inspection/Check must be performed after loosening any flight control cable to assure proper control surface operation. Refer to the appropriate control system s rigging procedures for the Inspection/Check maintenance practices. All 7-0 Page 1 1 May 011
