## Discrepancy

IN A HOVER, WAS AT A HOVER ABOUT TO TAKE OFF WHEN EVERYTHING STARTED SPEEDING UP, LOOKED AT THE TORQUE GAUGE AND SAW 120 PERCENT TORQUE, IMMEDIATELY LOWERED THE COLLECTIVE AND LANDED, AS LOWERED THE COLLECTIVE AND EVERYTHING RETURNED TO NORMAL.  MAINTENANCE IS COMPLYING WITH A OVERTORQUE INSPECTION IAW MM.
