o
NOT
use chip detector, part number (PN) 70351-08249-101, in the UH-
60A/L accessory module or in the UH-60L input module. Its probe is too short to
open the self-closing valves in these modules. That means oil and metal chips do
not pass the detector. The result is that there may be delayed warning of an
impending failure of an internal component.
Dispose of all on-hand stock of the bad chip detectors and inspect all Black
Hawks to see if any are installed. The bad chip detectors have PN 70351-08249-
101 stamped on the electronics pod attached to the end of the chip detector
cable. The vendor number—G5034—is stamped on the end of the chip detector
probe.
If you find bad chip detectors, replace them. The current TM 1-1520-237-23P-
2 (Nov 98), shows PN 70351-08249-103 (NSN 1615-01-263-8725) as the re-
placement. But, PN 70351-08249-102 (NSN 1615-01-106-1944) is also OK.
The TM will soon be updated to add PN 70351-08249-104 (NSN 1615-01-
459-7960) and the following:
CAUTION
Do not use PN 70351-08249-101 chip detector. If installed,
replace with chip detector PN 70351-08249-104.
