overheat sensing circuit found during a scheduled inspection.
The actions specified by this AD are intended to correct the
connection of the thermal switch to the cockpit indicator light, to
notify the flight crew of an overheated battery, and to prevent a
thermal runaway of the battery, an in-flight fire, and subsequent
loss of control of the helicopter.
