Step 3: Install the Air Box
The air box is molded with a dogleg in it to aim the eyeball ventilator
directly at the occupants of the aircraft, as well as to allow them to
reach it easily for adjustment. This geometry also allows the box to
fit inside the cage structure at the mounting location. Figure 3
shows the general layout of the air box relative to the cage.
Align the pre-molded
NACA scoop section of
the air box with the cutout
you made in Step 1.
Verify that the air box
clears the cage structure
and relieve the mounting
flange, if necessary, to
achieve a good fit. When
you are satisfied, use a
#40 bit to drill four index
holes through the
mounting flange of the air
box and the inner
fuselage laminates only.
You will insert clecos into
these holes to hold the
box in position during the
bonding process.
Remove the air box and use coarse sandpaper to roughen the
inside of the fuselage shell around the NACA scoop cutout. Then
clean both the shell and the air box mounting flange with Acetone.
