LED Flashing Anti-Collision

Light Assembly

OPERATING INSTRUCTIONS:

Operational Voltage: . . . . . . . . .28 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.

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.

CONTINUED AIRWORTHINESS: The 70905 series LED anti-collision
light assembly is designed with 10 vertical columns consisting of 3 LEDs
each. Should any one LED or any vertical column fail, the unit must be
repaired or replaced.

INSTALLATION PROCEDURES: The following information is to assist in
the installation of a Whelen LED Flashing Anti-collision 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.

Using the “suggested mounting hole pattern” prepare the aircraft for
means to secure the LED Flashing Anti-collision Light assembly.

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.

Install the light assembly by first removing the lens. Insert the
appropriate hardware through the counter-bored holes, secure the
assembly and re-install the lens screws with 5-7 in./lbs. torque.

Check all avionics systems for interference from this installation.

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

TSO-C96a CLASS I
APPROVED

MADE IN THE U.S.A.

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.

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” hole in the center of the lens for bottom mount units.

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