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 and proper angle for
alignment.
C. Install left and right elevator using P/N 40065-1 spacer, AN4-12A bolt and AN4-11A bolts in center
and outboard hinges. Connect elevator control arm and check travel 27° ±1° up and 17°±1° down.
D. Connect elevator trims tabs and check for proper travel.
E. Vertical Stabilizer: Install forward attachment loosely with NAS6207-68 bolt. Using either no shims
(normal) or if a gap exist, use one or more of the following P/N 21209T001 (.125") and/or P/N
21209T002 (.250") shim(s) at upper attach and P/N 21208T001 (.125") and/or P/N 21208T002
(.250") shim(s) at lower attach. Install hardware upper and lower and navigation light ground wire
(lower attach); tighten all vertical fin hardware per torque table (fig. 2-7). Using a string pulled tight
through upper rudder hinge and lower rudder hinge, check hinges for alignment fore, aft, left and
right. It is permissible to add (1) P/N 40207T005 (.050") or 40207T007 (.063") between the center
hinge bearing housing and vertical fin rear spar to achieve proper alignment.
F. Install the wire deflector cable and allow sufficient turnbuckle travel to permit tensioning of the
deflector cable. Attach and tension cable to 35 ±3 Lbs.
G. Install the rudder using AN4-11A bolts, connect navigation light ground wire to rudder horn
bolt, and connect navigation light power wire. Install rudder cables and check travel 22° left
and right from center.
