EQUIPMENT LIMITATIONS:

An approved Anti-Collision / Position Light System consists of at least 2 flasher/current source units, each connected to a LED anticollision and position light lighthead.

Certain types of installations may require additional testing.

CONTINUED AIRWORTHINESS:

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

Note: To reduce eye strain, use an optical filter such as dark glasses or a blue covering dome during LED inspection.

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

The conditions and tests required for TSO approval of this article are minimum performance standards. It is the responsibility of those installing this article either on or within a specific type or class of aircraft to determine that the aircraft installation conditions are within the TSO standards. TSO articles must have separate approval for installation in aircraft. The article may be installed only if performed under 14 CFR part 43 or the applicable airworthiness requirements.
