We must inform you that the wiring harness on your UH-60 Fleet requires an immediate
Safety check. Insummary, the Attitude Heading Reference System (AHRS) includes
Equipment, hardware and three wiring harnesses. Maintenance technicians have reported that
since bolt the pilot and the copilot have the same P3 connector, It is possible for the dual J1
and J2 connectors to be swapped during installation. If the connectors are inadvertently
swapped, the AHRS will continue to function but the information provide will be shown on the
opposite Horizontal Situation Indicator / Vertical Situation Indicator ( HIS / VSI) displays.
We advice yours your aviation technicians perform a one – time visual inspection for correc
Installation of the W1 and W2 Harness. Technical Publications will be update.
