Lift devices of the Boeing 727-232, consist of three leading edge flaps (Krueger flaps) located on the inboard lower surface of each wing, four leading edge slats on the outboard portion of the wing, and inboard and outboard trailing edge flaps (see figure 3).
The trailing edge flaps are driven by two completely independent systems.Each drive system normally is hydraulically powered; electrical power is available for alternate operation.
Each trailing edge flap is actuated by two flap transmission assemblies. The transmission assemblies on the outboard flaps are connected through torque tubes and gearboxes to a hydraulic motor which is the primary driving source.
Another separate set of torque tubes and gearboxes interconnect the transmission assemblies on the two inboard flaps. This system is driven by a single hydraulic motor. Power to the motors is controlled by two differential control valves with feedback modulation from the power transmitting torque tubes.
