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

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.
