5.2 Elevator Trim Tab
The action is transmitted from the trim lever via a Bowden cable to the trim tab,
reacted by a pair of springs. The mechanism will be fitted later
.
5.2.1 Elevator trim tab
a) If desired paint the elevator trim tab hinge
The hinge is steel and being downwind of the exhaust outlet can be subject to
corrosion. Painting or keeping it greased will ensure longevity.
b) Tap the elevator trim tab hinge pin out about 10mm, and cut this off. Tap the
pin back into place.
c) Drill a tiny hole, lockwire size, at each end of the hinge, either side of the hinge
pin but not through the hinge pin.
d) Wirelock these holes, to prevent any chance of the hinge pin falling out as it
wears over time.
e) If not already done, rivet the elevator trim tab hinge to the trim tab.
f) Rivet the trim tab to the lower side of the trailing edge of the starboard elevator
half, Figure 92.
Elevator halves are handed, choose the correct one to place the slots
for the eyebolt nuts to the underside.
Align the tapered part of the trim tab with the tapered part of the
elevator.
Use between five and ten 3.2mm diameter steel rivets, rather than
anything larger due to the small diameter of the trailing edge tube. Drill
the underside of the elevator trailing edge.
If desired, leave the actual riveting on of the tab until the elevator
halves are mounted on the aircraft, to keep the tab out of the way.
However, it is worth drilling all the holes at this stage.
