1.0 Introduction & Description
Introduction: Airglas, Inc. has designed and manufactured for more than fifty-five years, a full line of
composite skis that dramatically increases the usefulness of the aircraft by allowing it to operate on snow
or frozen surfaces. The installation of the GLH3000 Hydraulic Wheel Ski Kit allows the Piper PA-18, PA-
12, CC-18, S-18-180 and Sky International, Inc. (Aviat) A-1 series aircraft to operate on paved or
hard surfaces, and snow. The ski is pushed down as a sliding door closes the opening in the ski and
causes the tire to ride up on top of the door. The skis are actuated by a hydraulic cylinder on each
ski and an electric/hydraulic or hand pump to provide operating pressure. The door closes off the
wheel opening, thus creating the performance characteristics of a “straight ski”. When the airplane is
on snow, deploying to the ski position dramatically improves the takeoff performance (compared to
other skis). The simplicity of this design allows for a low maintenance high performance ski kit. This
is a design that Airglas, Inc. started in the year 2004, using the successful LH4000 as a platform.
Description: The GLH3000 ski installation consists of essentially 3 systems;
1. The Mechanical System – This includes the ski with all attaching hardware (interface to the
gear leg) and the rigging components.
2. The Hydraulic System – This includes hydraulic lines (both onboard and external), hydraulic
actuating cylinders (on the skis), all the hydraulic fittings on the skis, and the hydraulic pump.
3. The Electrical System – This includes pressure switches, a circuit breaker, wiring, a control
switch and indicator lights (the electric pump is covered under the hydraulic system).
Instructions for installation of this kit are detailed within this manual.

3.0 Installation
A modification to the landing gear must be accomplished at Airglas, Inc. for installation of the
skis. If the aircraft landing gear has been previously modified for the Airglas, Inc. LW2500 fixed
penetration skis, then no modification is necessary. 8.50 x 6 tires are required. Because there is a
hydraulic pump that is required to actuate the skis, provision for this pump installation must be
considered too. Airglas Inc. has designed the skis to work with an electric/hydraulic pump, but
they can also be operated with a hand pump.
Refer to drawings:
GLH3000-1-PA18 Installation (Piper type)
GLH3000-1-A1 Installation (Aviat)
GLH3000-6 Hydraulic System
GLH3000-7 Electrical Schematic
SKI ATTACHMENT
1. The existing brake caliper torque plate will need to be rotated about 45 degrees upwards to
provide clearance for the yoke. The torque plate on the caliper may need to have 4 new holes
drilled halfway between the exiting holes.
2. The brake lines may have to be modified or changed to allow for the new position of the
caliper.
3. Prior to initial ski installation, the aircraft will need to be hoisted or jacked to attain clearance
enough to slide the ski beneath the tire. Once the ski is positioned, the aircraft may be
lowered to the ground.
4. The rod ends on the yoke can next be thru-bolted to the weldments.
5. The use of mechanical means to extend the forward Bungee, Safety Cable Assy. far enough to
attach it to the forward gear bolt will be necessary. Use caution when stretching the bungee.
(If a hoist is used to lift the aircraft, it may be possible to lift it
high enough to pivot the ski and attach the bungee assembly
without stretching it.)
6. Once the forward Bungee, Safety Cable Assy. is attached with the aircraft on the ground, the
rear Check Cable may be attached to the aft gear bolt.
7. Confirm the skis are at +1.5° (+1/-0) tip up in the ski position in flight with the ski in the
down position. (Measure relative to aircraft horizontal level position) No adjustment is provided
in cables. Contact
Airglas, Inc. if ski position is not within tolerance.
8. Make sure all hardware is installed, torqued, and cotter pinned as necessary.
Note: All hardware in this kit shall be installed and torqued IAW AC 43.13-1B Chapter 7, Par 7-40,
Table7-1 and table 7-2 .

(3.0 Installation, Continued)
COCKPIT CONTROLS
1. Select an appropriate location for the control panel in the cockpit within view and reach of the
pilot. (Usually an unoccupied instrument hole is sufficient.)
2. Determine the lengths of wire required to reach the Master side of the bus and route the wires
IAW AC 43.13 recommended practices.
3. Follow the wiring diagram provided to insure the connections are correct.
HYDRAULIC PUMP & LINE ROUTING
1. Use the original battery location for the hydraulic pump if it is available.
2. If the battery compartment cannot be used, a location in the baggage compartment may be
used (See Note #1).
3. The pump mounting must be able to sustain a 9G forward impact and remain secure.
4. Hydraulic lines must be routed and secured so that they do not interfere with flight controls
and are not able to chafe (See Note #1).
5. Power supply and control wires for the pump must be routed through the aircraft IAW AC
43.13 recommended practices.
Note #1: All electrical and hydraulic components located in the baggage or passenger
compartments must be protected (shielded) from damage by shifting cargo or other
damage.
Installation instructions for the Parker-Electro/Hydraulic pump.
(LH4000 and GLH3000)
1. Make sure that the polarity for the pump is correct.
BLUE 12 V or Black 24V (SKIS)GREEN 12V or Orange 24 V (WHEELS)
a. Switch sends power to blue or black wire during “Ski” selection.
This will pressurize the “UP” port of the pump.
b. Switch sends power to the green or orange wire when “Wheels” are selected.
This will pressurize the “DOWN” side of the pump.
On (GLH3000) skis make sure the “UP” Port on the pump goes to the FWD fitting on
the deployment Cylinder.
2. When arranging the switch and indicator lights on the control panel, make sure that the
switch “UP” position is for Skis (Yellow Lights) and switch “DOWN” is for Wheels (green
lights).
NOT following these instructions WILL make the system OPERATE INCORRECTLY.

4.0 Control and Operation
Control and Operation Information: The door for the GLH3000 Ski is actuated by the
electric/hydraulic pump (preferred) or a manually operated hand pump in the cockpit. The
electric/hydraulic pump is controlled via a 3 position toggle switch and indicator lights that are
located on the instrument panel.
1. When the switch is lifted up, the cylinder will extend and slide the door under the tire. While
the switch is held up an operation indicator yellow light will illuminate showing the ski position
has been selected and the pump is cycling. When the cycle is complete, a second (Skis
Locked) yellow light will illuminate and stay on to confirm full deployment of the skis. As the
switch is released the operation light will extinguish, but the position locked light will remain lit
as long as the skis are extended.
2. When the switch is pressed down, the door will retract and expose the tire. While the switch is
held down an operation indicator green light will illuminate showing the wheel position has
been selected. When the cycle is complete, a second (Wheels Locked) green light will
illuminate and stay on to confirm retraction of the skis. When the switch is released the
selector light will extinguish, but the position locked light will remain lit as long as the skis are
retracted.
3. Low speed taxiing and steering may be enhanced by applying one brake during the cycling of
the door to the open position. Holding the brake will impede the actuation of the door and
allow the opposite sliding door to cycle independently. By extending only one wheel at a time,
the pilot will have increased maneuvering capability on certain snow conditions. This would be
particularly advantageous during solo operations.
CAUTION
Avoid landing on non-frozen surfaces while in the ski configuration. High friction contact on the ski
bottoms may cause high drag and increased wear to ski bottoms.
WARNING
Partial or incomplete actuation of the skis to either configuration is not recommended during landing
or take-off procedures.

5.0 Servicing Information
Mechanical System – The skis themselves are virtually maintenance free with the top of the
ski being Carbon Fiber and Fiber Glass and the bottom of the ski is Ultra High Molecular
Weight Poly-ethylene (UHMW). The ski bottom has two runners that run the full length of the
ski and are made out of ¼” UHMW. The runners are designed to give tracking stability to the
ski and protect the bottom of the ski. When the runners have worn down more than 50%,
they will need to be replaced. Waxing the ski bottoms for decreased friction and improved
glide is recommended, especially in wet snow.
The Yoke Assembly (GLH3000-5), and Retaining Rod (GLH3000-5-6) need to be checked for
security and proper lubrication. Yoke pivots require light greasing (with any multipurpose
heavy duty wheel bearing grease) every 25 hours and the HMX-6G rod ends will need light
oiling (with LPS-2 or equivalent low viscosity oil) every 25 hours. The yoke is made out 4130
Chromoly Steel. The (GLH3000-10) Yoke Safety Restraining Cable system is designed to keep
the yoke from traveling over-center in the unlikely event of a rigging failure.
The Tail Wheel Bracket Kit (LW2500-18) is made of stainless steel angled brackets with a 5”
aluminum wheel with a solid urethane tire. The cartridge wheel bearings should be replaced
when damaged. When the tire has worn more than 50% the wheel should be replaced.
The rigging is made up of galvanized steel 5/32 cable for the ice cutter, safety cable, and
natural rubber 8020CW cold weather bungee rings for the front assembly and 5/32 cables for
the check cable assembly. The bungees should be kept out of direct sunlight and must not
come in contact with fuel or other chemicals. Any fraying of the sheathing should be noted
and inspected for rubber strand damage or degradation. Swaged ends and cables should be
inspected for fraying and slippage. Hardware should be inspected for security. Replace any
damaged components. Bungee’s should be replaced after 5 years in service or when defects
are noted.
Hydraulic System – The hydraulic system supplied with the skis uses an Electric/Hydraulic
Pump, (a hand pump is optional but not offered through Airglas, Inc.) to pump fluid to a
hydraulic actuating cylinder mounted on the ski. The Electric/Hydraulic Pump is intended to be
mounted behind the cabin area, preferably in the original aircraft battery location. Location is
optional, but G load must be accounted for in the mounting design and method. Hydraulic
lines are routed through the aircraft under the floor and out to the gear legs. Use bulkhead
style fittings clamped to the fuselage structure, and cable ties or clamps to mount the external
hydraulic lines to the landing gear and then connect to the hydraulic fittings on the ski
cylinder. The air is bled from the hydraulic system by cycling the skis several times. The
electric pump is self bleeding. MIL-H-5606 or compatible hydraulic fluid is required for filling,
