LED Flashing Anti-Collision
Light Assembly
OPERATING INSTRUCTIONS:
Operational Voltage: . . . . .24 - 32 VDC
Average Input Current: . . .0.45 Amps
Peak Input Current: . . . . . .2.5 Amps @ .25 Seconds
EQUIPMENT LIMITATIONS:
Rotorcraft for which type certificate was applied for after
April 1, 1957 to August 11,1971:
The anti-collision system must produce a minimum of 100
effective candelas in Aviation Red or White, 360° around the
vertical axis, 30° above and below the horizontal plane. A single
beacon will meet this requirement.
Rotorcraft for which type certificate was applied for after
August 11, 1971 to February 5, 1976:
The anti-collision system must produce a minimum of 400
effective candelas in Aviation Red or White, 360° around the
vertical axis, 30° above and below t he horizontal plane. This
beacon does not meet this requirement.
Rotorcraft for which type certificate was applied for after
February 5, 1976:
The anti-collision system must produce a minimum of 150
effective candelas in Aviation Red, 360° around the vertical
axis, 30° above and below the horizontal plane. A single
beacon will meet this requirement.
Certain types of installations may require additional testing.
CONTINUED AIRWORTHINESS: The 70905 series LED anti-
collision light assembly is designed with 5 columns consisting of
5 LEDs each, and 5 columns consisting of 4 LEDs each. Should
any one LED or any vertical column fail, the unit must be
repaired or replaced.
NOTE: To reduce eye strain, use an optical filter s uch as dark
glasses or a blue covering dome during LED inspection. Inspect
the lens. Replace if there is any excessiv e scratching, pitting,
discoloration or cracking.
INSTALLATION PROCEDURES: The following information is
to assist in the installation of a Whelen LED Flashing Anticollision Light System.
1. The installation procedure described in the following text
Aviation
will be confined to a single li ght in stallation, but is identical
for multiple light installations.
2. Prepare the aircraft for means to secure the LED Flashing
Anti-collision Light assembly (see reference AC 43.13-2A
Chapter 4)
3. 28 VDC (+) and (-) ground leads equipped with an
appropriate sized breaker to be supplied to the LED
Flashing Anti-collisio n Light Assembly System. Both leads
must be connected by an approved FAA connection.
TSO-C96a CLASS I
APPROVED
The conditions and tests required for TSO approval of this
article are minimum performance standards. It is the
responsibility of those installing this a rticle either on or w ithin
a specific type or class of aircr aft to determi ne that the ai rcraft
installation conditions are within the TSO standards. TSO
articles must have separate approval for inst allatio n in aircraf t.
The article may be installed only if perform ed under 14 CFR
part 43 or the applicable airworthiness requirements.
Insure that the wire leads are all clear of any obstructions and
ty-wrap as required.
4. Install the light assembly by securing to aircraft using the
appropriate, approved hardware. Note: Lens mounting screws
installed with 5-7 in./lbs. of torque.
5. Check all avionics systems for interference from this
installation.
6. A flight check should be performed by a properly certified pilot.
7. All inverted (bottom) mounted units shall require waterproofing
of the mounting hardware. An applicati on of si ngle-part silic one
(RTV) or equivalent applied over top of the mounting hardware,
after installation, is recommended. Reference page 2 for an
illustration. Inverted and/or standard mounted units, when
necessary, may require waterproofing around any open area
where water could get in. Specifically, the lens to the flasher
base assembly, and the flasher base assembly to the aircraft.
Note: It is permissable to drill a 1/8” drain hole in the center of
the lens for bottom mount units.
8. Update aircraft records, complete Form 337 and obtain FAA
field approval for installation, as necessary.
