Section A. Main Landing Gear <strong>Assembly</strong><br />
The Super Sport aircraft can have either a conventional or tricycle landing gear<br />
configuration. The configuration can be changed at any time during assembly<br />
or even after the aircraft has been completed and flown.<br />
These instructions describe the installation of the landing gear as though this<br />
were the final assembly, however the gear will have to be removed to cover and<br />
paint the aircraft. Therefore, all illustrations showing finalization of hardware<br />
(such as torqued nuts, cotter pins, safety wire, etc.) are there for your future<br />
reference.<br />
The Super Sport main landing gear consists of a single-piece aluminum gear<br />
bow that is mounted to the fuselage between two points that allow the gear to<br />
pivot as loads are applied.<br />
Axles bolt to the gear legs to mount the wheels and disc brake assemblies.<br />
This gear design has proven to be extremely rugged, has low aerodynamic drag,<br />
and is virtually maintenance free.<br />
This section is illustrated with the landing gear in its normal, upright position.<br />
You may find it advantageous to invert the fuselage while installing the gear -<br />
this helps keep the hardware in place while you get the nuts threaded on the<br />
bolts. If you choose to invert the fuselage, invert the illustrations as well to<br />
reduce confusion while you are working.<br />

2. Ream the four fuselage gear attach bushings to .3750". Drill out the<br />
5<br />
/16" holes in P/N: 13016.102 lower pivot blocks to 3 /8"<br />
3. Press the four roll pins into the gear leg at the locations shown. Use an<br />
arbor press if one is available. If not, the pins can be carefully driven in<br />
with a small hammer. If you use a hammer to drive the pins in, hold them<br />
with a pair of pliers initially to keep your fingers out of the way.<br />
4. Attach the gear leg to the fuselage with the hardware called out in Figure<br />
A-3. Note that the gear is not symmetrical - the tapered face must be<br />
installed toward the rear. Figure A-3 shows the tricycle (aft mounting)<br />
configuration. The conventional landing gear configuration is similar,<br />
although longer bolts are used.<br />
NOTE<br />
To help you achieve the proper fit of the gear leg between the rocker and<br />
separator disks, the mounting hole through the rocker disks has been<br />
drilled .010" off center. If the gear leg seems too tight or too loose between<br />
the disks, rotate one or both of the disks on each side 180° until the<br />
leg is held with as little play as possible without binding.<br />
NOTE<br />
There are threaded holes in the Delrin ® gear rocker blocks. They will not<br />
affect the installation - they are from the tooling process. Deburr the threaded<br />
holes as required to remove any remaining material on the surface from<br />
the threading process.<br />
OPTIONAL WHEEL PANTS<br />
If you are installing wheel pants, refer to the instructions that came with<br />
the wheel pant kit before installing the axles.<br />

5. Bolt the axles and brake torque plates to the gear legs using the<br />
hardware shown. The plates should be oriented at about the 4 o’clock<br />
position, viewed from the axle end. Torque the nuts to 50 to 70 inchpounds.<br />

Section B. Wheel and Brake <strong>Assembly</strong><br />
1. Working on a clean workbench, remove the wheel bearing retaining<br />
spring ring, the cover washers, the felt wiper, and the bearing from the<br />
wheel halves. Work on one wheel half and bearing at a time to prevent<br />
mixing the parts. Pack the bearing with wheel bearing grease by putting<br />
a golf ball sized lump of grease in the palm of one hand and pressing the<br />
edge of the bearing into the grease. Rotate the bearing a little and repeat<br />
the packing motion. You should see the grease oozing up between the<br />
rollers. Turn the bearing over and pack the grease in from the other side,<br />
all the way around. When the bearing is fully packed with grease, put<br />
it and the rest of the bearing hardware back into the wheel half and<br />
reinstall the retaining ring, making sure that it is fully seated in its<br />
groove. Repeat for the bearing in the other wheel half and repeat the<br />
whole process on the other wheel.<br />
2. Remove the nuts and bolts holding the wheel halves together and<br />
separate the wheel. Insert a tire tube into a tire, dusting the tube with tire<br />
talc to eliminate friction between the two. If the tire has a red dot painted<br />
on the sidewall, align the valve stem with the dot. Press the valve stem<br />
through the hole in the wheel half, and then press the wheel half fully<br />
into the tire. It is helpful to put a very small amount of air in the tube,<br />
just enough to help it hold its shape. Press the opposite wheel half into<br />
the tire from the other side, visually aligning the mounting holes. Pass<br />
a bolt through the wheel halves and brake disc, press the halves<br />
together, and start a nut on the bolt threads. Install the other bolts in a<br />
similar manner and torque them to 90 inch-pounds.<br />
CAUTION<br />
Be careful not to pinch the tube between the halves of the wheel as<br />
they come together. Listen and feel for crisp, metal-to-metal contact<br />
of the wheel halves before tightening the bolts. If you have difficulty<br />
ensuring that the tube is not caught between the wheel halves, a ring<br />
of thin cardboard can be taped in place around the wheel half split<br />
line to help guard the tube.<br />
WARNING<br />
Completion Date<br />
_______________<br />
Never inflate the tire unless all the wheel bolts are installed and properly<br />
torqued. Always deflate the tire before loosening any wheel bolt.<br />
The wheel halves will be very forcefully ejected by the tire pressure if<br />
these precautions are overlooked.<br />

3. Slip the inner brake pads onto the caliper pins if they were removed for<br />
any reason. Lubricate the brake caliper pins with a dry film lubricant<br />
such as LPS-1.<br />
4. Slide the brake caliper onto the brake torque plate from the inboard side.<br />
The caliper should have its bleeder fitting oriented downward.<br />
5. Slide the wheel and tire assembly onto the axle, followed by the axle<br />
spacer and the axle nut. Tighten the axle nut firmly and rotate the tire<br />
by hand to squeeze out the extra grease from the bearing rollers and<br />
races. Loosen the nut one-half turn, then re-tighten it slowly until all<br />
play has been removed from the bearings. This play can be felt by<br />
grasping the tire at the top and pushing it in and out. When the nut is<br />
adjusted, advance or retreat it just far enough to align the closest cotter<br />
pin hole. Double check the bearing play and readjust as required. A<br />
very small amount of play is preferable to having the bearing being too<br />
tightly preloaded.<br />
6. Install a cotter pin to secure the axle nut.<br />

7. Set the outer brake pad in place, trapping the brake disc between the two<br />
pads. Secure it with the bolts that were supplied with the wheel and<br />
brake kit. Torque the nuts to 75 to 80 inch-pounds for final assembly.<br />

Section C. Tailwheel Installation<br />
The tailwheel assembly consists of an aluminum tail spring, a steerable, fullswiveling<br />
tailwheel, and steering chains and springs that are connected to the<br />
rudder to allow maneuverability of the aircraft during ground operations.<br />
1. Round the corners of the tailspring clamp plate with a file.<br />
2. Ream the mounting holes in the clamp plate to .1875"<br />
3. Ream the fuselage bushing to .3125" for the tailspring mounting bolt.<br />
4. Ream the two holes in the fuselage mounted tailspring clamp plate to<br />
.1875".<br />
5. Install the tailwheel springs using the hardware shown. Torque the<br />
tailspring clamp plate bolts to 20 to 25 inch- pounds and the forward tail<br />
spring attach bolt to 100-140 inch-pounds.<br />
6. Bolt the tailwheel assembly to the tailwheel spring using the bolt, nut,<br />
and washer shown. Torque the tailwheel mounting bolt to 270 to 300<br />
inch-pounds.<br />
NOTE<br />
The steering springs and chains will be installed when the aircraft is complete<br />
and is at its empty weight (refer to the Final <strong>Assembly</strong> chapter for the<br />
weight and balance definitions and procedures) prior to initial taxi testing.<br />
Completion Date<br />
_______________<br />
7. Install a tailwheel steering chain to each lower control horn on the<br />
rudder using a P/N: 10055.000 wire clip. Attach a steering spring<br />
between each steering arm on the tailwheel and the corresponding<br />
chains with a minium of slack. Leave two or three extra links on the<br />
chain to allow for further adjustments until you are satisfied with the<br />
ground handling characteristics of the aircraft.<br />

7. Install the elastomer springs and friction washers onto the nose gear<br />
piston in the order shown. The AN4-5A bolt, washers, and rubber stop<br />
washer are installed by lining up the piston in the piston rod bearing and<br />
compressing the elastomer springs by using the strut as a lever.<br />
Carefully thread in the AN4-5A bolt a minimum of one turn and then<br />
you can relax pressure on the strut. Use a liquid thread locker on the<br />
AN5-4A bolt to back up the lock washer for final assembly and torque<br />
the bolt to 60 to 85 inch-pounds. As with the main gear legs, the system<br />
is very robust and virtually maintenance free.<br />

with structural adhesive and let cure. When positioning the plug, be sure<br />
to get it far enough into the pivot shaft to clear the cotter pin hole.<br />
9. Press the nose wheel fork bearings in place using a liquid bearing lock<br />
to secure the installation. The upper fork bearing will need to have a flat<br />
section filed into the flange to clear the wheel pant attach tab.<br />

10. Lubricate the lower end of the nose gear strut with wheel bearing<br />
grease. Assemble the stack of Belleville washers, being very careful to<br />
orient them as shown. Place a thrust washer above and below the stack.<br />
Install the fork assembly and washer stack on the gear strut and secure<br />
with the axle nut and cotter pin. Attach a fish scale to one of the ends<br />
of the axle. Tighten the nut until it requires a pull of 10 to 12 lbs on the<br />
fish scale to keep the fork moving. Note that the force required to start<br />
the fork moving will likely be higher than this. You may wish to only<br />
temporarily install the cotter pin in the strut at this time, as the nut may<br />
need slight adjustment later once taxi testing begins and all of the<br />
components have 'seated' in their proper positions.<br />

11. Remove the nuts and bolts holding the halves of the nose wheel together<br />
and separate them. Insert the inner tube into the tire, dusting the tube<br />
with tire talc to eliminate friction between the two. If the tire has a red<br />
dot painted on the sidewall, align the valve stem with the dot. Press the<br />
valve stem through the hole in the wheel half, then press the wheel half<br />
fully into the tire. If the valve stem comes equipped with a nut and<br />
washer, remove them and press the stem through the wheel hole. Once<br />
the stem is in place, reinstall the nut and washer and carefully tighten.<br />
It is helpful if you put a very small amount of air in the tube, just enough<br />
to help the tube hold its shape. Insert the bearing spacer into the wheel<br />
and press the opposite wheel half into the tire from the other side,<br />
visually aligning the mounting holes. Put a bolt through the wheel<br />
halves, press the halves together, and start a nut on the bolt threads.<br />
Install the other bolts in a similar manner and torque the nuts to 100 to<br />
140 inch-pounds. Inflate the tire to 20-25 psi.<br />
CAUTION<br />
Be careful not to pinch the tube between the halves of the wheel as<br />
they come together. Listen and feel for crisp metal-to-metal contact of<br />
the wheel halves before tightening the bolts. If you have difficulty<br />
ensuring that the tube is not caught between the wheel halves, a ring<br />
of thin cardboard can be taped in place around the wheel half split<br />
line to help guard the tube.<br />
WARNING<br />
Never inflate the tire unless all the wheel bolts are installed and properly<br />
torqued. Always deflate the tire before loosening any wheel bolt.<br />
The wheel halves will be forcefully ejected by the tire pressure if these<br />
precautions are overlooked.<br />

12. Install the two spacers into the wheel and install the wheel assembly<br />
onto the fork. Slide the nose wheel axle into the wheel until the same<br />
amount of axle shows on both sides of the fork. Install a washer and an<br />
axle nut evenly onto each end of the axle. Put a cotter pin through one<br />
of the axle nuts to hold it in place and adjust the wheel bearing preload<br />
by tightening the other nut until all bearing play is eliminated. Rotate the<br />
tire to ensure that it does not bind or drag, then install the final cotter pin.<br />
Again, do not completely bend over the legs of the cotter pins until final<br />
assembly.<br />

Section E. Tail Skid Installation<br />
A tail skid is mounted to the aft, lower empennage to prevent damage in the<br />
event of over-rotation during takeoff or landing. It also provides an excellent tiedown<br />
point for the tail of the aircraft.<br />
1. Ream the forward attachment bushing in the fuselage to .3125".<br />
2. Ream the mounting holes in the clamp plate and the tail skid plate to<br />
.1875".<br />
3. Attach the tail skid to the fuselage at the aft attachment plate.<br />
4. Align the tail skid so the forward attachment tab is centered over the<br />
forward attachment bushing. Match-drill the forward attachment tab on<br />
the tail skid with a 5 /16" bit. Remove the tail skid and deburr.<br />
Completion Date<br />
