Horizontal Stabilizer |
|
| Step 1: Cleco the
HS-1014 and HS-1015 Long and Short Stringers together making two
stringer assemblies as shown in Figure 1. With #30 drill final-drill the
five outboard holes on each of the stringers witch are common to both
stringers. Leave the eight inboard holes alone for now. Insert the two
stringers assemblies into the stabilizer by pulling back the skins (not
shown in the figure) and dropping them into the notches in the inspar
ribs. This will require lifting the entire assembly out of the cradles
slightly . Cleco the skins to all the ribs and stringers.

| Step 2: Cleco the rear
spar assembly to the inspar ribs , then final-drill the holes common to
the spar and ribs using a #30 drill. The rear assembly is symmetrical;
There is no left or right. |
|
| Step 3: Cleco the
HS-1016 Stringer web to the forward side of the two stringer assemblies,
then, using an angle drill, final-drill the holes common to the
stringers and stringer web with a #30 drill. Match-drill the four holes
in both flanges of the stringer web into the inspar ribs using the same
drill. |
|
| Step 4: Final-Drill all
skin holes to size with a #40 drill. Try to follow a system of drilling
and moving clecos to prevent missing any holes. |
 |
| Step 5: Mark the
empennage fairing screw holes on the skins and the inboard nose and
inboard inspar so that they are not dimpled or riveted later. |
|
| Step 6: Mark the parts
as you disassemble the stabilizer and deburr all edges and holes |
|
| Step 7: Dimple the
skins and rib flanges for the exterior rivets. However, do not dimple
the holes marked in step 5 or the hole in each small tab of the inspar
ribs. |
|
| Step 8: Machine
countersink the holes in the flanges of the front and rear spars and the
3/32" holes of the stringers |
|
| Step : 9 Prime all parts
if desired, in preparation for final assembly. |
