CONTINUED AIRWORTHINESS:

If any bank of LEDs fail, the lighthead module should be checked. If
the module checks good, replace the flasher.

Note: An anti-collision light will automatically shut-off after 9-10
flashes if a failure is detected.

INSTALLATION PROCEDURES:

1. Consider areas or locations designated by the aircraft
manufacturer. Check that breakers are properly rated.

2. Attach the flasher using the (4) 0.156 dia. mounting holes.

3. Connect the inputs according to the chart shown. Connections
to be in accordance with FAA approved methods.

4. Check all avionic systems for interference from the installation

5. A flight check should be performed by a certified pilot

6. Update aircraft records, complete form 337 and obtain FAA
field approval for installation, as necessary
