fwd or aft bushings to achieve the
required incidence angle.
B. Install left and right struts using AN5-
6A bolts on lower attach (strut to
fuselage) and AN6-12A bolts on
upper attach (strut to horizontal
stabilizer).
C. When installing a new strut or new strut
parts, accomplish as follows:
Figure 7-9: Empennage Exploded View
1. With new strut(s) adjust fork ends
as required to bring the strut as
close as possible to lower fuselage
attach without touching. The strut
should be centered fore and aft with
fork ends. The forks should be
shimmed with a P/N 40024-3
spacer and P/N 21194 washers as
required (different thicknesses are
available) and at least one P/N
21194-C copper crush washer.
Then torque to 160 - 190 inch-
pounds and align with attach points
simultaneously. The lower strut/
plates can now be trimmed to fit if
needed and drilled with a .312
(5/16") drill bit and bolted into place
using AN5-6A bolts. If only re-
torque is required and torque
cannot be achieved with old shims,
the replacement of the copper crush
washer only should be sufficient to
regain correct torque (100-140 inch-
pounds) and proper angle for
alignment.
