3.1.2.5. Installation
To facilitate the rigging process, pre-set the forks in the front struts to eight
threads past jam nut and five threads past the jam nut on the rear struts.
Raise wing to bring spar fittings into position in the wing fittings on the
fuselage.
Install the forward bolt first then the rear bolt.
Install the forward strut beginning with the upper attach point first. Make
sure to install the tie-down ring before the strut.
With the forward strut attached to the wing, raise the wing tip and slide the
fork down on the fuselage fitting and install the bolt.
Repeat the above steps for the opposite wing.
To check dihedral angle, first insure that the fuselage is level laterally, then
stretch a string from wing tip to wing tip along the front spar.
Measure down from the string to the top of the fuselage front wing hinge
fitting. The measurement should be three inches plus or minus 1/8-inch.If
the measurement is too low, adjust the forks on the front struts an equal
amount on each side.
One half turn adjustment on both forks results in a 1/8 inch change in the
height of the string.
Once the proper measurement is obtained the wings must be checked to
insure that they are set square with the fuselage.
Assemble a tool to check the rigging by using a piece of straight aluminum
angle of sufficient thickness to not be flexible. On one end attach a metal or
wood block that is 13/22 inches thick. Place this bar with the block facing
outboard along the front spar in the area between the jury strut attach fitting
and the strut attach fitting. Place the level along this bar. The reading
should be the same on each wing. If not, it indicates that one wing is
adjusted higher than the other. To correct, shorten the strut on the high
wing side and lengthen the strut on the low wing side and equal amount.
When the level reading is the same on both sides recheck total dihedral
again with the string.
Once dihedral is set, the rear struts can be installed and the washout of each
wing set. Start by installing the rear strut on one wing. To check washout,
attach another block 3/8 inch thick to the rigging tool. Check the angle the
fuselage is sitting at by placing the digital level along the tube at the lower
door sill. This is the baseline number. Hold the tool with the 3/8 inch block

toward the rear along the last full rib at the outboard end of the aileron bay.
Place the level on the bar. This measurement should match the fuselage
number. If not, adjust the fork in or out until the numbers match. Repeat
the process for the opposite wing.
NOTE
It is very important that the washout of the wings be equal. If washout is
unequal it will cause the airplane to constantly bank and not fly straight.
Repeat the process for the other wing.
Attach the jury struts to the wing and the jury strut clamps to the struts.
Anti-chafe tape should be put on the jury strut clamp where it will make
contact with the strut.
The jury strut lugs and the spreader bar should be attached to the bottom of
both jury struts before attaching the lugs to the clamps on the struts.
Check the jury struts to make sure they are vertical before tightening the
clamp bolts.
Run the aileron direct cable through the fairleads on the front strut, around
the pulley and up into the wing.
Put the aileron balance cable back through the fuselage fairlead and attach
to the opposite wing cable.
Install and rig aileron (See section 3.5.2, Aileron Installation and Rigging).
Install and rig flap (See items 3.5.9, Flap Removal/Installation, and 3.5.10,
Flap Control Mechanism Removal/Installation)

Assemble the LH and RH elevator to the stabilizers using four AN394-55
clevis pins, four AN960-10 washers and four AN380-2-2 cotter pins.
Attach the two 350-TL0015 turnbuckle forks to the two elevator links using
one AN3-6 bolt, two AN960-10 washers, one AN310-3 nut, and one AN380-
2-2 cotter pin per fork.
Join the top of the elevator bell cranks together using one 310-TL0023 upper
link, one AN3-5 bolt, one AN960-10 washer, one AN310-3 nut, one AN380-2-
2 cotter pin, one AN6-5A bolt, one AN960-616 washer, and one MS21083N6
Nut.
Install the 310-TL0025 lower link using the AN393-13 clevis pin, one AN960-
10 washer, and one MS24665-208 cotter pin.
Attach the cables to the forks threading the ends into the turnbuckle barrel
evenly.
With the elevators against the down stop, tighten the lower cable turnbuckle
to pull the rear control stick away from the back of the front seat. The top
turnbuckle may need to be loosened during this process. When the back
stick is rearward enough to clear the seat, tighten up the top turnbuckle to
remove slack from the system. Final tightening will be done later.
Using a digital level or other suitable device, measure the up and down
travel of the elevators. Proper travels are listed in Table 3-1.When using a
digital level, there is no need to level the fuselage. Measure the angle of the
fuselage at the tube on the lower door sill. This will be the zero point. For
example, if fuselage is sitting at 12 degrees tail down from level 25 degrees
up travel will be obtained when the level reads 13 degrees up from level.
You must add 12 degrees to the number displayed because the zero point is
12 degrees down from level. Likewise to measure down travel you must
subtract the 12 degrees from the number displayed because the zero point is
12 degrees down from level. In this case proper down travel is obtained
when the level reads 41 degrees down from level. The travels can also be
checked using a bubble protractor but the fuselage must be leveled before
starting.
3.5.4.5. Verification
After proper travels are verified, insure that both cables are tensioned
equally at 2.75 ± .25 in deflection with 4 pounds of pressure measured from
bottom of jack screw.
Also ensure that the control stick moves easily. Turnbuckles may not have
more than three threads exposed on either end of the barrel. Safety
turnbuckles with safety clips or safety wire.

If new liner tubes are being installed, they will have to be drilled to match
the stabilizers. If new stabilizers are being installed you must use new liner
tubes.
To set and drill new liner tubes and stabilizers, first install the tubes in the
fuselage with equal amounts extending out on either side. Mark the tubes
with a marker for a reference point to maintain positioning while drilling.
Take each stabilizer and make a mark ¾ inch from the open end of the
forward and aft tubes on both sides of the stabilizer.
Lay a straight edge on the stabilizer so that the ends rest on the marks made
in the previous step. Make a mark where the straight edge touches the
tubes. This will be the tangent point on the tube ¾ of an inch from the edge
of the tube. Drill through the tubes at each of the four points marked using a
#12 drill. Do not try to drill straight through the tube from one side. If the

measuring was done properly the holes will be directly across from one
another.
After the stabilizers are drilled, take one stabilizer and install the forward and
aft liner tubes in it up to the reference marks made previously.
Match drill the liner tubes on one side of the stabilizer.
Put a short 3/16 inch diameter bolt in the hole just drilled in the liner tube.
This will keep the tube from moving when drilling the other side.
Flip the stabilizer over and match drill the other side.
Remove the short bolt and install the AN3-14 bolt in the forward side and the
AN3-16 bolt in the aft side. This will create a subassembly to be installed on
the airplane.
Slide the stabilizer onto the fuselage.
Slide the other stabilizer onto the other side of the fuselage. Match drill the
top and bottom of the liner tubes in the same manner described above and
install the bolts.
Next, attach the upper and lower tail brace wires using the appropriate
hardware.
Level the fuselage laterally.
Tighten the upper tail brace wires and check with a level until the stabilizers
are level.
Tight the lower tail brace wires evenly to achieve proper tension and adjust
the upper wires as necessary to make sure that the stabilizers remain level.
Proper tension on both upper and lower tail brace wires are adjusted as
follows. Tail brace wires shall be adjusted to obtain 7/16 deflection (+or-
1/16 inch) with a centered 10 lb. (+or- 1 lb.) load.

Attach Mounting Hub Half
o Be certain that the magneto switch is “OFF” and that both magnetos
are grounded. Chock the aircraft wheels to prevent movement. Clean
dirt and oil residue from the engine flange. Refer to Figure 6-1 for
views of the propeller assembly.
o Be certain the two springs are installed in the mounting half of the
hub.
o Place spacer (if applicable), rear spinner bulkhead, and the hub
mount half, as shown in Figure 6-1, on the engine mounting flange.
Vertical orientation of the hub is recommended for ease of assembly.
The hub and spacer (if applicable) must sit flush on the mounting
flange and the rear spinner bulkhead. NOTE: Bolt breakage will occur
if not flush. Place special lock washers, under the bolt heads, on 6
mounting bolts (AN6-XXA) and insert into the 6 mounting holes inside
the hub mount half. Each special lock washer works in pairs with the
“ramped” sides facing each other. See Figure 6-2. Position the hub
mount half, rear bulkhead, and spacer (if applicable) on the engine
flange with the six mounting bolts running through the engine flange.
Torque the 6 mounting bolts using a star pattern similar to Figure
6-3. See Table 1 for mounting bolt torques.
Insert Blades in Hub Mounting Half
o Each blade has a camber, round side (decal) and a flat side. With the
round side facing forward, and the hub in the vertical position, insert
one blade at a time into the hub mounting half. You may need to hold
the upper blade with one hand.
o Place the hub clamp half over the blade shanks. Place special lock
washers, under the heads, on clamp bolts (AN6-15A) and insert into
the hub cover half. Hand tighten the clamp bolts into the threaded
clamp bushings, taking care to start with an even gap between hub
halves on both sides. NOTE: Once fully torqued, the gap will close up
and the hub halves will meet on the hub sides.
o Rotate each blade’s leading edge slightly towards the aircraft. Insert
the pitch cartridge into the slot of the hub clamp half. You should be
able to feel the springs depress and push back when you press on the
cartridge. Take a blade with one hand and depress the pitch
cartridge. Rotate the blade’s leading edge, away from the aircraft,
Legend Aircraft Maintenance Manual – AL18 54

Date of Revision: 9/27/2013
until it engages the pitch cartridge. Rotate the second blade until it
engages the pitch cartridge. Grab each blade together and rock into
the pitch cartridge. You should hear a click when the blades are
seated properly. Slight play is normal after blades are locked in. Rock
the blades back and forth to center the pitch cartridge in the slot.
o Using a calibrated torque wrench and following the pattern shown in
Figure 6-3. Tighten the bolts in ¼ to ½ turn increments (this will take
several passes) until the proper torque given in Table 1is reached.
o NOTE: Have your tachometer calibrated by a professional before
performing this next operation. With the brakes on, run the engine
full throttle to verify your desired static RPM. CAUTION: YOU
SHOULD NEVER EXCEED THE MAXIMUM RPM RATING FOR
YOUR ENGINE. If you are not seeing your correct static RPM, be
certain the tach was properly calibrated. You may contact Sensenich
to purchase a slightly lower or higher pitch cartridge if you feel this is
the problem due to your density altitude. CAUTION: YOU SHOULD
NEVER MASK AN ENGINE PROBLEM WITH A PITCH CHANGE. If
you are unsure, please contact the factory.
Changing the Pitch
o If changing the pitch is necessary, first loosen the 6 clamp bolts until
the blades are loose, then hand tighten the bolts to maintain an even
hub gap in each side. NOTE: The special lock washers will click
loudly when loosened. Unlock each blade by depressing the pitch
cartridge while rotating each blade’s leading edge towards the
aircraft. Remove the first pitch cartridge. Follow steps 6 and 7 of the
Installation Procedure. NOTE: This is considered a model
change and must be noted in the logbook.

10. Structural Repair
No major structural repairs or structural alterations, as outlined in ASTM
F2483, AC 43.13, or in this manual are authorized at this time.
American Legend Aircraft Company must be contacted for guidance on any
repairs required. Please go to American Legend’s website for latest contact
information at http://www.legend.aero
Upon contacting Legend Aero and describing the structural or major repair a
mechanic wants to handle, American Legend Aircraft Company will upon its
sole approval provide guidance to the mechanic or repair shop including
internal work instructions for assembly, assembly drawings if applicable and
technical support and guidance for specific repair and testing through a
letter of authorization (LOA). This LOA needs to be referenced in the repair
aircraft logbook. Items such as repairing covering and painting can be
handled per instructions and guidance in the subsequent section of this
manual and are not considered structural repair. American Legend Aircraft
Company may simply sell replacement parts to the repair facility or mechanic
to replace and install in lieu of guidance for repairing the part to maintain
quality and compliance to applicable design and quality standards.
Legend Aircraft Maintenance Manual – AL18 65

Date of Revision: 9/27/2013
11. Painting and Coating
All aircraft are covered, maintained, and repaired using the Star Gloss
covering system (STC SA4503NM)
Aircraft can be washed with a mild detergent and after 90 days from paint
application can be waxed with a quality automotive product.
Other than normal washing and waxing no maintenance is required.
For more detailed information refer to manufactures covering and painting
manuals.
Inspection Procedure for fabric. The basic concept is that the paint and
coatings should remain in good shape to protect the fabric.
Inspect the overall condition of the paint and coatings
If the fabric is flexible and resilient when pushed hard with a knuckle it is
good and no further inspection is required.
If the paint is brittle, cracked and ring wormed and readily cracks when
pushed hard with a knuckle it is subject to further inspection. As long as
there are no big chucks out of the paint, and there is no sun exposed fabric,
the airplane is still considered air worthy, but should be monitored for
problems continually until the next annual inspection
If there are significant areas of the paint and coatings missing, advanced
peeling, sun-exposed fabric the aircraft could be considered un-airworthy
and the American Legend Aircraft company should be contacted for further
repair instructions.
