Surfaces And Controls - MAULE Jetasen M-4 Maintenance Manual

AILERONS AND FLAPS:
The ailerons and flaps are aluminum alloy structures covered with 2024-T3 skin.
The aileron control system consists of a chain drive connecting the two control wheels
and is attached to the necessary cables which are routed over pulleys through the fuselage
and into the wing section to the aileron horns.
The flap control system consists of a control lever, which has two active positions, 15°
and 35°. This is connected to the control cables which are routed to the flap through the fu-
selage and wing to the flap bellcrank which operates the flap by means of a push-pull rod
attached to the inboard hinge fitting.
ELEVATORS:
The elevators have chrome molybdenum (4130) internal structure covered with fiber-
glass fabric. Inspect for corrosion. Drain grommets should be kept open. The hinge at-
tachments should be lubricated with light engine oil. Accumulations of dust and dirt on hing-
es should be removed.
STABILIZERS:
The stabilizers have chrome molybdenum steel (4130) internal structures covered with
fiberglass fabric. Inspect for corrosion including elevator hinges and struts.
Steel tie rods brace the stabilizers to the vertical stabilizer and fuselage. These tie rods
should not be rigged tighter than necessary so high loads may be imposed on other parts of
the tail surfaces or fuselage. In adjusting the tension of the tie rods, care should be taken so
that marring the rods will not result. The threads at each end of the tie rods must close the
inspection holes in the end fittings. An inspection of the tie rods and fitting should be made
to check cotter pins, lock nuts, and to see if they have been damaged in any way.
RUDDER:
The rudder structure is very similar to the elevators. No maintenance other than inspec-
tion for corrosion is needed. The hinges should be cleaned and lubricated with light engine
oil at frequent intervals. The cable attachment points should be checked for wear and corro-
sion.
TRIM AND RUDDER TABS:
These surfaces have low carbon steel frames with aluminum alloy skin (2024-T3).
These surfaces need no maintenance other than inspection for corrosion. The hinges
should be lubricated at frequent intervals using light engine oil.
