LED Position, Anti-Collision and
Infrared Light Assembly
©2010 Whelen Engineering Company Inc.
Form No.14419A (060711)
EQUIPMENT LIMITATIONS:
An approved lighting system consists of two lights, one located
on each wingtip. The baseplate must be mounted parallel to the
vertical and horizontal centerlines of the aircraft to project the
patterns properly. A separate flasher assembly, such as model
7145750 or 7145751 is required for each light assembly.
The Infrared light is a non-TSO function.
Certain types of installations may require additional testing.
CONTINUED AIRWORTHINESS:
The forward position light is designed with 4 Green LEDs or 5
Red LEDs. The tail position light is designed with 2 LEDs. The
Infrared light is designed with 12 LEDs. The anti-collision light is
designed with 36 LEDs.
If any one bank of LEDs fails, the flasher module should be
checked. If module checks good, replace the lighthead. If any
one LED 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. Inspect the lens.
Replace if there is excessive scratching, pitting, discoloration or
cracking.
Note: The anti-collision light will automatically shut-off after 9-10
flashes if a failure is detected.
INSTALLATION PROCEDURES:
The following information is to assist you in installing a Whelen
light system. The installation procedure described in the
following text will be confined to a single light installation, but is
identical for multiple light installations.
1.
Choose the appropriate Model 90569( ) light assembly.
2.
Using the mounting detail information on page 2, prepare
the aircraft for means to secure the LED light assembly.
Remove any existing mounting adapters.
3.
Connect the light inputs according to the chart shown.
Connections to be in accordance with FAA approved
methods.
4.
Remove the lens retainers and carefully remove the lens.
Using appropriate hardware, install the light assembly and
insure that all leads are clear of any obstructions. Ty-rap
as required. Secure the light assembly using vibration
resistant threaded fasteners. #6, 100° countersink is
recommended.
5.
Carefully reinstall the lens and retainers.
6.
Waterproof the lightbase to aircraft. Apply single-part
Silicone (RTV) or equivalent around any open area
where water could get in.
7.
Check all avionics systems for interference from this
installation.
8.
A flight check should be performed by a properly
certified pilot.
9.
Update aircraft records, complete Form 337 and obtain
FAA field approval for installation, as required.
