MANUAL REVISION B
27 July 2011
THIS MANUAL INCLUDES INFORMATION PROPRIETARY TO
Airglas, Inc.
AND SHALL NOT BE USED TO MANUFACTURE OR REPRODUCE ANY PART OR
ASSEMBLY WITHOUT THE PRIOR WRITTEN PERMISSION OF
Airglas, Inc.
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:

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
w ithout 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.
