MAULE AEROSPACE TECHNOLOGY, INC. MAINTENANCE MANUAL M-8-235 SECTION I GENERAL DATA GENERAL DESCRIPTION: Type: Five place high wing cabin monoplane. Engine Installation: Single tractor engine in nose of fuselage. Wing: Strut braced, two spar, metal covered, modified USA 35-B airfoil. Fiberglass wing tips.
"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.

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.

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 SB provides for larger stainless steel turnbuckles and corrosion re- sistant steel fasteners and attachment details for the elevator cables.

(Note: earlier model Maule airplanes used a hard seal filler material, which may crack or lose adhesion with the tube.
MAULE AEROSPACE TECHNOLOGY, INC. MAINTENANCE MANUAL M-8-235 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...

MAULE AEROSPACE TECHNOLOGY, INC. MAINTENANCE MANUAL M-8-235 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.
MAULE AEROSPACE TECHNOLOGY, INC. MAINTENANCE MANUAL M-8-235 10. RUDDER TAB: This tab is interconnected with the aileron system to automatically coordinate aileron and rudder controls for simplified handling in the air. (It may be used as a rudder trim tab to make the airplane trim in cruise.) This tab may be ground adjusted by changing the...
MAULE AEROSPACE TECHNOLOGY, INC. MAINTENANCE MANUAL M-8-235 FABRIC REPAIRS: (Applicable to polyurethane paint on Ceconite fabric only) REPAIRS: 1. Small holes and damaged areas can easily be repaired without removing the existing paint topcoat. 2. Trim the damaged area to a rectangular or circular shape.
The aft fuselage section is covered with Ceconite fabric and standard dope and paint fin- ish as per Maule Specification S-17. Later models are finished with polyurethane or acrylic urethane paint in accordance with Maule Specifications S-40 or S-41, respectively. This fab- ric need not be pulled or punch tested.
MAULE AEROSPACE TECHNOLOGY, INC. MAINTENANCE MANUAL M-8-235 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 AEROSPACE TECHNOLOGY, INC. MAINTENANCE MANUAL M-8-235 LANDING GEAR, WHEELS AND BRAKES MAIN LANDING GEAR: The main landing gear consists of separate left and right side heat-treated (7075-T651) aluminum spring legs, which are bolted to a square tube truss in the bottom of the fuselage structure.

MAULE AEROSPACE TECHNOLOGY, INC. MAINTENANCE MANUAL M-8-235 Slide lock ring (73B) over the threaded end of the fork spindle and run nut (A1) down until it bottoms on the lock ring. Tighten the nut moderately and note whether or not there is any end play in the bearings.
MAULE AEROSPACE TECHNOLOGY, INC. MAINTENANCE MANUAL M-8-235 Tighten the bracket bolt and back off enough to install the cotter pin. There must be no looseness or play between the bracket (71B) and the spring. Install the connector springs, using the heavier spring on the right side. Install the springs so that the light spring is compressed approximately 1/2 to 3/4 inch.
MAULE AEROSPACE TECHNOLOGY, INC. MAINTENANCE MANUAL M-8-235 Baffling should be checked for security and the rubber sealing extensions should be checked for wear and security. When the cowl is installed, these sealing extensions should lay up, forward or inboard, and provide a good seal against the cowl.
MAULE AEROSPACE TECHNOLOGY, INC. MAINTENANCE MANUAL M-8-235 If installed, two (2) auxiliary wing tip fuel tanks, fifteen (15) gallon (or twenty-one (21) gal- lon) capacity, are mounted in the second from the outboard wing bay. They are fuel transfer tanks and simply supply fuel to the main tank through a small vibrator pump.

MAULE AEROSPACE TECHNOLOGY, INC. MAINTENANCE MANUAL M-8-235 The battery is considered fully charged at a hydrometer specific gravity reading of 1.265. A low charge would be 1.225 or lower. Operating with a low charge will shorten the life of the battery and can be prevented by recharging or operating with the electrical equipment turned off until the battery has been sufficiently recharged.
