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 the horizontal plane. This beacon does not meet this
requirement.

Aviation

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 such as dark glasses or
a blue covering dome during LED inspection. Inspect the lens. Replace if
there is any excessive scratching, pitting, discoloration or cracking.

INSTALLATION PROCEDURES: The following information is to assist in
the installation of a Whelen LED Flashing Anti-collision 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. Using the “suggested mounting hole pattern” prepa re the aircraf t for
means to secure the LED Flashing Anti-collision Light assembly.

3. 28 VDC (+) and (-) ground leads equipped with an appropriate
sized breaker to be supplied to the LED Flashing Anti-collision
Light Assembly System. Both leads must be connected by an
approved FAA connection. Insure that the wire leads and the
pressure venting tube are all clear of any obstructions and ty-wrap
as required. The pressure venting tube may be trimmed to
minimum length of 1” from base.

4. Install the light assembly by first removing the lens. Remove the 3
screws that attach the mounting adaptor plate.

5. Install adaptor plate onto aircraft. Re-mount the unit onto the
adaptor plate and re-install lens with 5-7 in./lbs. of torque.

6. Check all avionics systems for interference from this installation.

7. A flight check should be performed by a properly certified pilot.

TSO-C96a CLASS I
APPROVED

Page 1

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.

8. All inverted (bottom) mounted units shall require waterproofing of
the mounting hardware. An application of single-part silicone (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.

9. Update aircraft records, complete Form 337 and obtain FAA field
approval for installation.
