AV-426-ICAO
Radio Controlled Solar Aviation Light
Installing the Light Assembly to the Frangible Stake Mount
The completed AV-426-ICAO - mount plate assembly is to be mounted on the stake in firm soil (not
loose sand, screenings or other unbound material).
a. Fit the AV-426-ICAO on the top of the mounting plate. Insert bolts through the four holes in the
mount, entering from the bottom. Install a penny washer and a Nylock nut on each bolt. Tighten
Nylock nuts.
b. Use a sledge hammer to drive the stake into the soil at the chosen location. Drive the stake down
until the bottom of the stake sleeve is at ground level.
c. Fit the AV-426-ICAO and mounting plate assembly on top of the stake. The point of frangibility
should be completely clear of the stake sleeve or ground support hardware. Use the socket head
cap screws supplied to hold the frangibility point above the sleeve. Using a 6mm Allen key, tighten
the bottom socket head cap screws against the stake sleeve.
Note:
After adjustments, ensure all nuts and bolts are tightened securely and all tools, spares and
packaging are removed from the runway.

a. Mount the base plate to the concrete using 4 x M8 concrete bolts.
b. Fit the frangible mounting plate onto the concrete base plate and secure using the M8 x 16 SHCS
c. Level the light mounting plate using a spirit level.
d. Fit the AV-426-ICAO to the light mounting plate using M8 SHCS, large flat washers and Nylock
nuts.
e. For further adjustments on levelling the light, see next section on leveling the light.
