Self Contained Light Assemblies - 70900( ) Series - Whelen Engineering Company OR5001V Installation And Service Manual

SELF CONTAINED LIGHT ASSEMBLIES
MODEL 70900 ( ) SERIES
FLASHING ANTI-COLLISION LIGHT ASSEMBLY
70900 series are FAA TSO compliant self-contained anti-collision lights for fixed wing aircraft. An external power
unit is not required. Conservative lab life results greater than 20,000 hours. No EMI or RFI produced. All units meet
the minimum requirements stated in FAR Parts 23 & 25 for anti-collision light systems used on fixed wing aircraft,
Ref; Class III (100 effective candela) of SAE AS8017a minimum performance standards. STC SA615EA approved.
Models 7090004 & 7090005 are designed to replace existing light assemblies with the 3-3/4" (95mm) dia. mount-
ing pattern (Ref. Whelen HRCFA series, 90081 series, and "old style" rotating beacons). It has the same mounting
hole pattern. No modification to the aircraft is required.

Operation
Equipment Limitations: The Model 70900 series LED anti-collision
light assembly meets the requirements of FAR 23.1401, 25.1401 and
91.205(c)(3). "If certification for night operations is requested, the
airplane must have an anti-collision light system that consists of one
or more approved anti-collision lights located so that their light will
not impair the flight crew members vision or detract from the con-
spicuity of the position lights."
Continued Airworthiness: The 70900 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.
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. Prepare the aircraft for means to secure the LED Flashing
Anti-Collision Light assembly (see reference AC 43.13-2A, Ch. 4).
3. 14 and 28 VDC (+) and (-) ground leads equipped with an appro-
priate sized breaker to be supplied to the LED Flashing Anti-Colli-
sion 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 securing to aircraft using #6-32 x
3/8" (maximum length) approved hardware. Note: Lens mount-
ing screws installed at 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 unused mounting holes. An application of single-part sili-
cone (RTV) or equivalent applied into mounting holes is recom-
mended (see illustration on page 11, Fig.11A). Inverted and/or
standard mounted units, when necessary, may require water-
proofing around any open area where water could get in.
Specifically, the lens to the flasher base assembly, and the flash-
er base assembly to the aircraft.
8. Update aircraft records, complete Form 337 and obtain FAA field
approval for installation. If not covered under STC eligibility list.
