FUSELAGE FRAME

Basically, the fuselage frame consists of 1025 and X4130 tubing acetylene welded to form the body
structure of the fuselage.

Tubing members are shown in the small circles on the accompanying drawing in order that they may be
identified in the event repairs are necessary in the field. Tubing size and type are shown on the back of the
fuselage frame drawing.

Fairing clips, landing gear fittings, gussets, and brackets are welded to the fuselage frame. These parts are
shown on the fuselage drawing and identified by number only.

In the event of serious damage to the landing gear yoke section, complete assembly may be ordered for
replacement.

Should the front or rear landing gear attachment cluster be damaged beyond repair, it is possible to obtain
this complete cluster. The front component, (5-252-2L-L/R) or rear component, (5-252-3L-L/R), may be
obtained separately or a complete assembly including front and rear clusters may be obtained.

The entire fuselage frame structure is coated with rust preventative primer at the factory. Upon making
any repairs in the field, care should be taken to thoroughly clean the repaired areas and recoat with rust
preventative primer. Zinc chromate or palidin has been found to be an excellent corrosion proofing and
adds materially to the life of the structure.

Navigation light wiring which is attached along the upper fuselage longeron is installed at the factory as
standard equipment. Wiring extends from rear of seat to fuselage vertical fin.

All repairs should be made in accordance with Civil Aeronautics Manual 18.
