The Maule M-5 was designed and built to give you the airplane you have always wanted. It is fast, comfortable, and easy to fly, yet no light airplane is safer than the Maule M-5. Its sturdy construction means you will not have to pamper it to enjoy long years of trouble-free service.
MAULE AEROSPACE TECHNOLOGY, INC. MAINTENANCE MANUAL M-5-220C LOG OF REVISIONS Description Date page(s) Added Log of revision page. Added special maintenance procedures for floatplanes based in coastal areas or an otherwise corrosive atmosphere. 07/19/99 Revised the inspection procedure concerning the horizontal stabi- lizer strut lower attach stub tubes.
30H x 26W x 21L (Approx.) *2500 lb. gross weight is applicable if Maule Service Letter No. 51 is complied with. **20° and 40° Flap Setting is applicable if Maule Service Letter No. 48 is complied with. Rev. B 5/38...
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 every effort to sepa- rate dissimilar metals with primers and coatings during manufacture, but there are some loca- tions (such as rivets in wing skins) where this is impossible.

M-4 struts with the 7/16” dia. lower fork. 1/2” dia. fork is required for all later models. CAUTION: Item (a)(4) of AD# 98-15-18 is very misleading as Maule never drills holes in struts to at- tach 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.

NOTE: Check top side of rear elevator horn and cable and bottom side of forward elevator horn and cable if yellow color-coding paint is visible. If missing, paint per Maule Service Bulletin No. 30. 13. CAUTION: At inspection hole in tail, visually check the pivoting action at the control cable attachment points over the full range of rudder and elevator trav- el.
16. Lubricate door hinges and latches and seat tracks. CAUTION: Carefully inspect all door hinge bolts and nuts for condition and security. If door hinges are secured with elastic nuts, they must be replaced with castle nuts and cotter pins. Refer to Maule Service Letter No. 61.

Es- tablish the rudder “Neutral Position” by measuring (and holding) a distance of 6” between the backside of the rudder pedal(s) to the face of the interior firewall.
FABRIC REPAIRS: (Applicable to Polyurethane paint on Ceconite fabric only) (This aftermarket application is approved for this model - no M-5-220C's were manufactured with this covering and paint) REPAIRS: Small holes and damaged areas can easily be repaired without removing the existing paint topcoat.
MAULE AEROSPACE TECHNOLOGY, INC. MAINTENANCE MANUAL M-5-220C the patch to be applied. This application aids in total adhesion to the topcoat and offers a fresh chemical adhesion base for the repair patch. Allow prime to dry for 4 hours. Apply a coat of urethane adhesive (thinned one to one (1:1) with urethane adhesive thinner by volume) to the primed area slightly larger than the repair patch size.
MAULE AEROSPACE TECHNOLOGY, INC. MAINTENANCE MANUAL M-5-220C FUSELAGE: The fuselage is a welded truss type structure having an integral vertical tail fin. Chrome molybdenum steel (4130) is used for all tube members, control fittings, floor supports and seat members. Doorframes and other nonstructural parts are made of cold rolled steel (1008 to 1015) or stainless steel (per customer’s request).
These surfaces need no maintenance other than inspection for corrosion. The hinges should be lubricated at frequent intervals using light engine oil. 20° and 40° Flap Setting is applicable if Maule Service Letter No. 48 is complied with. LANDING GEAR, WHEELS AND BRAKES...
