"electrolyte corrosion". Salt water and chemicals act as an electrolyte between dissimilar metals and can start a strong corrosive action over a short period of time. Maule makes eve- ry effort to separate dissimilar metals with primers and coatings during manufacture, but there are some locations (such as rivets in wing skins) where this is impossible. - Page 7 MAULE AIRCRAFT CORPORATION MAINTENANCE MANUAL M-4/C/S/T Revised 7/99 Cont’d Care should be taken in the disposal of candy wrappers, paper scraps, cigarette butts, etc. These can work their way under the floorboards and become a fire hazard, mois- ture trap and could jam the control cables.

MAULE AIRCRAFT CORPORATION MAINTENANCE MANUAL M-4/C/S/T Revised 7/99 INSPECTION GUIDES At 25 Hour Total Time, perform 50 Hour Inspection as described below. At 50 Hour Total Time and every 50 hours thereafter: A. POWER PLANT 1. Perform appropriate inspection as called for in the engine manufacturer's Operator's Manual. - Page 9 9. Drain sumps of fuel tanks. CAUTION: Quick drains are required in all fuel tanks and if not installed, comply with Maule Service Letter No. 32 and Service Bulletin No. 5. 10. Check tires for inflation and cuts. At 100 Hours Total Time and every 100 Hours thereafter, perform the 50 hour inspection plus the following: A.
- Page 10 M-4 struts have the 7/16” dia. lower fork thread. 1/2” dia. is required for later models. CAUTION: Item (a)(4) of AD# 98-15-18 is very misleading as Maule never drills holes in struts to attach cuffs, door clips or any hardware and it is illegal to do so since there are no approved holes in the wing struts under the TC data.
- Page 11 Long Island City, NY Tucker, GA NOTE: Maule Service Bulletin No. 9 covers corrosion resistant parts replacement and is particularly recommended for airplanes operating in a potentially corrosive environment. Compliance to this Service Bulletin provides for larger stainless steel turnbuckles and corrosion resistant steel fasteners and attachment details for the elevator cables.

Page 13: Rigging Procedures
MAULE AIRCRAFT CORPORATION MAINTENANCE MANUAL M-4/C/S/T RIGGING PROCEDURES 1. LEVELING: Laterally: The airplane can be accurately leveled laterally using the front spar attach bolts. Turn these two bolts so that a flat on the head is "up". Fabricate two equal length spacers (1½ inch minimum length) which can be placed on the bolt heads. - Page 14 MAULE AIRCRAFT CORPORATION MAINTENANCE MANUAL M-4/C/S/T 4. TAIL ASSEMBLY: With the airplane in level position, the stabilizers should be leveled at their rear spars. The hinge line should be straight from tip to tip. The vertical stabilizer should be plumb at the hinge.
- Page 15 MAULE AIRCRAFT CORPORATION MAINTENANCE MANUAL M-4/C/S/T 7. RUDDER: On earlier models, the rudder stops are not adjustable. The rudder travel should not change if this part of the airplane is not damaged. If these need to be adjusted, it can be done by welding on to the end of the stops to decrease the travel and filing the stops off to increase the travel.

Page 16: Lubrication
MAULE AIRCRAFT CORPORATION MAINTENANCE MANUAL M-4/C/S/T LUBRICATION 1. Main wheel bearings - Use good quality wheel bearing grease. 2. Oleo shock struts – For P/N 4015B oleo spring, use New Holland No.134 hydraulic oil or Ford Tractor No. ESN-M2C134-D. 10W30 engine oil may also be used. For P/N 4161B oleo spring use API GL-4 or GL-5 85W-140 gear oil. -
Page 17: Fabric Repairs
MAULE AIRCRAFT CORPORATION MAINTENANCE MANUAL M-4/C/S/T FABRIC REPAIRS: (Applicable to polyurethane paint on Ceconite fabric only) (This Installation is approved for retrofitting - no M-4's were originally manufactured with this covering/paint) REPAIRS: 1. Small holes and damaged areas can easily be repaired without removing the existing paint topcoat. -
Page 18: Major Component Parts
Powder coating is recommended if complete strut is being refinished. WARNING: Any unrepairable dents or punctures are cause for replacement of the strut. If airplane has the original unsealed struts, insure compliance with AD No. 98-15-18 (Maule SB No. 11) (See also page 7, item 7). FUSELAGE: The fuselage is a welded truss type structure having an integral vertical tail fin. -
Page 19: Surfaces And Controls
MAULE AIRCRAFT CORPORATION MAINTENANCE MANUAL M-4/C/S/T SURFACES AND CONTROLS 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. -

MAULE AIRCRAFT CORPORATION MAINTENANCE MANUAL M-4/C/S/T LANDING GEAR, WHEELS AND BRAKES MAIN LANDING GEAR: TOE-IN: If ground handling of the airplane makes toe-in suspect, inspect main landing gear as follows: 1. With airplane unloaded, jack-up airplane on one side and spin tire. If center groove runs true, do same on other side. - Page 21 MAULE AIRCRAFT CORPORATION MAINTENANCE MANUAL M-4/C/S/T ASSEMBLY OF OLEO STRUT: Reassembly is the reverse of steps 5 and 6. Fill cylinder 1/2 full of hydraulic oil. Align cylinder head bolt holes with cylinder bolt holes and insert spring assembly. Install cylinder head bolts, filler plug and safety.
- Page 22 MAULE AIRCRAFT CORPORATION MAINTENANCE MANUAL M-4/C/S/T Remove wheel rim through-bolts. Cont’d Clean rims thoroughly. Remove bearings and check for scoring, galling and corrosion. Replace as required. Regrease and assemble. (Tire and wheel rims are prebalanced. Balance points are usually marked by a colored dot.) Lightly inflate to prevent pinching of tube when tightening through-bolts.
- Page 23 MAULE AIRCRAFT CORPORATION MAINTENANCE MANUAL M-4/C/S/T Recheck reservoir level and fill as necessary. MAINTENANCE HINTS ON HYDRAULIC BRAKES: Excessive pedal travel: Probable cause Corrective Action 1. Normal wear of brake pad at wheel 1. If pad is worn thin, replace with new pad.

Page 24: Maule Tailwheel
This unit should be lubricated as noted in the inspection guide in the manual. Keep air pressure at 40 psi. If tailwheel is a Maule SFS-P8B and if shimmy of the tailwheel becomes a problem, it should be lubricated and adjusted as follows: (See Fig. 1 for detailed breakdown.) A. - Page 25 MAULE AIRCRAFT CORPORATION MAINTENANCE MANUAL M-4/C/S/T (1) or two (2) shims will be required to remove any bearing clearance. Too many shims will cause the bearings to drag when the nut is tightened. Rev. B 4/13/16...
