C. Rigging and Adjustment
CAUTION: VERIFY FREE AND CORRECT MOVEMENT OF STABILATOR TAB. WHILE IT
WOULD SEEM SELF-EVIDENT, FIELD EXPERIENCE HAS SHOWN THAT THIS
CHECK IS FREQUENTLY MISINTERPRETED OR NOT PERFORMED AT ALL.
ACCORDINGLY, UPON COMPLETION OF STABILATOR TRIM RIGGING AND
ADJUSTMENT, VERIFY THAT THE STABILATOR TAB MOVES UP WHEN THE TRIM
WHEEL IS TRIMMED DOWN; AND, THAT THE STABILATOR TAB MOVES DOWN
WHEN THE TRIM WHEEL IS TRIMMED UP.
(1) Level the airplane. (See 8-20-00.)
(2) Position control wheel by adjusting the turnbuckles on the stabilator control cables to obtain
7/8 ± 1/8 inch of control shaft travel between contact with the primary up stop on the stabilator
and secondary stop on the left hand control column shaft.
(3) Position and secure tee bar (control column) 1/2 inch ± 1/4 inch off forward tee bar stop.
(4) Check for proper stabilator trim cable tension as given in Figure 2. If cables were
disconnected, rotate trim control wheel several times to allow cables to seat and recheck
tension.
(5) Recheck control wheel position for 7/8 ± 1/8 inch of control shaft travel between contact with
the primary up stop on the stabilator and secondary stop on the left hand control column shaft.
With the control wheel forward and stabilator on primary down stop, check for 1/4 inch
minimum clearance between tee bar and secondary forward stop.
(6) Secure stabilator in neutral position. Refer to Figures 2 and 3.
(7) Turn trim control wheel until aft end of turn buckle of right trim cable is approximately two
inches forward of double pulleys at top of rear bulkhead.
(8) Check that trim screw is turned down until cotter pin stop in top of screw is contacting plate on
horizontal support rib of trim assembly.
(a) If stop is not contacting plate, and links between the screw and trim control arm are not
disconnected, disconnect the two by removing nut, washers and bolt.
(b) With turnbuckle still two inches from pulley, turn screw down until pin contacts plate.
(9) Check rod end on tab actuating arm for approximately six threads forward of jam nut.
(10) Connect links to trim screw and secure with bolt, washers and nut.
(11) Turn the trim wheel until trim tab streamlines with neutral stabilator.
(12) Check bubble of protractor over neutral tab; then check tab travels specified in Figure 2.
Degree of travel on protractor is determined by taking difference between protractor reading at
neutral and up position, and neutral and down. With airplane level, bubble must be centered at
each reading. To obtain correct travel:
(a) Disconnect links at actuating arm rod end.
(b) Turn rod end in or out, as required.
(c) Connect links to actuating arm rod end.
(d) Secure jam nut on actuating arm rod link
(13) Turn trim wheel full travel. Check for turnbuckle clearance and location of tab indicator.
(14) With the stabilator and trim in all extremes of travel, check to insure that there is no
interference between turnbuckles and pulleys.
(15) Check to insure that stabilator up and down stops are contacted before the tee bar stops are
contacted.
(16) With the stabilator held securely against either stop, determine the free play of the stabilator
tab. Total free play, measured at the tab trailing edge, shall not exceed 0.06 inches.
