NOTE
• All rubbing operations on acrylic
plastics shall be done with as light
a pressure as possible.
• Rubbing the plastic surface with a
dry cloth will cause scratches and
build up an electrostatic charge
which attracts dust particles.
• Do not use the following materials
on acrylic plastics: gasoline, alco-
hol, benzene, hexane, xylene, ace-
tone, carbon tetrachloride, fire
extinguisher or deicing fluids, lac-
quer thinners, or window cleaning
sprays because they soften the plas-
tic and/or cause crazing.
Fuel Section
The fuselage fuel section is located immedi-
ately aft of the rear pressure bulkhead. (See
Figure 1-5.)
The fuel section is located as follows:
• Frames 22 to 24: Models 23, 24, 24B, D,
F, and 24E, when installed
• Frames 22 to 25: Models 25, 25B, and D
• Frames 18 to 25: Model 25C, which has
long-range tanks installed
Tailcone Section
The tailcone section extends aft from the fuel
section to the empennage. The tailcone entry
door (Figure 1-14) is located at the bottom of
this section. On some airplanes, the door is
hinged at the forward edge and drops down
when released by quick-release thumb latches,
allowing access to the batteries, electrical
components, fuel filters, refrigeration equip-
ment, engine fire extinguishers, and hydraulic
components. On airplanes without hinges, the
door is secured by camlock fasteners.
There is no cockpit indicator to warn the pilot
if the door is open.
