EQUIPMENT LIMITATIONS:
An approved forward position and anti-collision system consists of at
least two lightheads, one mounted on each wingtip mounted behind a
clear lens, and each connected to a model 71234( ) Flasher.
Certain types of installations may require additional testing.
CONTINUED AIRWORTHINESS:
The wingtip anti-collision light is designed with 24 LEDs. The position
light is designed with 6 LEDs. If any one fails, the unit must be
repaired or replaced. NOTE: To reduce eye strain, use an optical filter
(such as dark glasses or a blue covering dome) during LED
inspection.
Note: The anti-collision lights will automatically shut-off after 9-10
flashes if a failure is detected.
SHROUD REMOVAL PROCEDURE:
If justified by the Aircraft installation and additional FAA testing of
compliance to TSO-C30c and TSO-C96a the shroud may be
removed.
1. Remove and discard the two, #6 screws that are used to secure
the shroud. Carefully remove the shroud. CAUTION: Do not
touch the LED lens.
INSTALLATION PROCEDURE:
The following information is to assist you in installing a Whelen anticollision light system.
1. The installation procedure described in the following text will be
confined to a single light installation, but is identical for multiple
light installations.
2. Connect the inputs according to the chart shown. Connections
to be in accordance with FAA approved methods.
