aforementioned MWOs. Aircraft are also required to comply with ASAM UH-1-97-ASAM-05 which
reapplies paint to position lights after removal per UH-1-97-ASAM-02,
NOTE
UH-1 H/V aircraft which have the AN/ARC-186 radio and/or the AN/ARC-164 UHF
radio installed must have the lighting to the control disabled until NVG compatible
lighting for the control is available. Procedures for this is as follows:
1 If the C-1 0604/ARC-186 or the C-10606/ARC-186 is installed as a result of MWO
55-1520-210-50-14, disable the control head lighting wire by removing terminal lug for wire number
ARC1 86-19A22 from TB12, Pin 3. Cap and stow wire for future use, This wire may be reconnected when
the control is modified with NVG compatible lighting.
2 If the C-10604 or the C-10606 is not installed via use of an MWO (i.e. AN/ARC-186
radio is located in the rear of the aircraft, right side, on top of the previously installed RT-857/ARC-134
radio mount), disable the control head wire by removing terminal lug for wire number ARC134-35A20
from TB12, Pin 2. Cap and stow the wire for future use. This wire may be reconnected when the control
is modified with NVG compatible lighting.
3 If the RT-1354/ARC-186 (red lighting) is installed in lieu of the AN/ARC-115, the light-
ing must be disabled by cutting wire number ARC 115-3A22 going to pin C of the AN/ARC-115 radio
connector P1151. Cap and stow the wire for future use. This wire may be reconnected when the radio
is modified with NVG compatible lighting.
4 If the AN/ARC-51BX UHF radio or the C-9682B/ARC-164 havequick control is
installed, disable the lighting wire by cutting wire No. L122A20 going to Pin P of the C-6287/ARC-51 BX
or C-9682B/ARC-164 control connector No. P3801.
5 If the C-9682C/ARC-164 have quick control or the C-11721/ARC-164 control is
installed, the lighting may be enabled by reconnecting wire No. L122A20 going to pin Pof radio connector
P3801.
6 If the panel mount ARC 164 radio (RT 1518C) is installed with NVG compatible light-
ing, lighting to the radio may be activated by completing the connection of wire No. ARC 164-3A22 from
the ARC 164 radio connector No. P1, pin C to TB12, Pin 1. If the lighting is not NVG compatible, the
lighting must be disabled by disconnecting wire No. ARC 164-3A22 from TB 12, Pin 1. See para h(2)
below for avionics approved for NVG use.
7 Use of the ID-2192A/ARN-124
indicator is authorized for NVG missions in the
UH-1 H/V aircraft.
(c) OH-58A - MWO 55-1520-228-50-31
is required to be installed for NVG use.
(d) OH-58C - MWO 55-1520-228-50-32
is required to be installed for NVG use.
(e) OH-58D Kiowa Warrior - All aircraft from production and retrofit lines are considered ac-
ceptable for NVG use. No MWO is required. Use of the ANVIS display symbology system optical display
assembly is authorized. NVG use is prohibited when the Hamilton standard Pilot Display Unit (PDU) is
installed.
(f) CH-47D - CH-47D aircraft are authorized for NVG use when delivered with the excep-
tion of aircraft S/N 84-24187 and prior which are required to have MWO 55-1520-240-50-3 installed.
(g) AH-1 S - MWO 55-1520-234-50-1 and MWO 55-1520-234-50-4 are required to be
installed for NVG use.
(h) AH-1E, F, and P - MWO 55-1520-236-50-4 and MWO 55-1520-236-50-5 are re-
quired to be installed for NVG use.
(2) Update on ANVIS blue-green lighting upgrade/modification kits for avionics components.
(a) MWOs have been approved and ANVIS lighting upgrade/modification lighting kits on
avionics components listed below are available from USACECOM. Listed items have been identified
as the primary avionics components requiring ANVIS blue-green lighting modification/upgrade:
