2.6. INSTALLATION PROCEDURES FOR
THE DK100/DK120 AND THE N30A26 SE-
RIES MOUNTING KIT.
2.6.1. GENERAL. Model N30A26 Series Mounting
Kit (Cradle Type) is an aluminum extrusion with a
screw attached securing plate that provides rugged
mounting and protection of the beacon within the aircraft.
See Figure 3. The beacon should be mounted horizontal-
ly with the switch end forward, if possible. If vertical
mounting is necessary, switch end must be mounted
downward to prevent accumulation of dirt, grease and
water on the switch end.
2.6.2. CRADLE MOUNTING PROCEDURE.
A. Using Figure 3 as a guide, locate the four 0.290
inch (0.737 cm) diameter holes on 1.500 by 2.400 inch
(3.810 by 6.096 cm) centers. Be sure access to the se-
curing plate end is available for future beacon installa-
tion and removal. Approximately 4.5 inches (11.43 cm)
clearance should be allowed for beacon removal.
NOTE
The mounting bracket can be used as a template
to mark for drilling the holes prior to the instal-
lation of beacon. Always remove beacon from
mount prior to marking or drilling.
CAUTION
WHEN MOUNTING TO THE AIR-
FRAME, CHECK THE OPPOSITE SIDE
OF THE FRAME OR BULKHEAD FOR
DRILLING CLEARANCE.
WARNING
USE PROTECTIVE EYE EQUIPMENT
DURING DRILLING OPERATION.
B. After the four 0.290 inch (0.737 cm) diameter
holes have been located, drill the holes with an “L”
twist drill.
C. Secure the mounting cradle to the aircraft structure
with four 1/4-20 stainless steel screws and associat-
ed washers and nuts (not furnished), as shown in
Figure 3. Alternate mounting with threaded holes may
be employed where structure does not permit nuts on
rear side.
CAUTION
DO NOT ADD ANY UNAPPROVED
STAMP, ETCHING, OR LABEL TO
THE BEACON CASE OR END CAPS.
2.6.3. INSTALLING DK100/DK120 BEACON IN-
TO N30A26 SERIES MOUNTING KIT.
A. If the securing plate and its attaching hardware
are already attached to the main body of the mounting
cradle, remove them.
B. Make sure that the beacon case and water
switch are free of grease or film. If in doubt, wipe
clean with mild detergent.
