Narrative:

The tower requested flight to exit at taxiway echo and proceed across 6 left and taxi via ramp to gate. After fully retarding the throttles (power levers) and with the first officer receiving taxi instructions from the tower, I turned to taxi up taxiway echo, at which point I advanced the power levers and saw a rapid rise and a momentary overtemp on the engine temperature gauges. At that time I immediately closed the power levers and selected ground fine pitch. The temperatures cooled rapidly and we taxied in, west/O further incident. After shutdown I physically pulled the propellers through and visly inspected the engines, seeing no outward signs of damage I went immediately to the maintenance supervisor and reported the incident. Both the supervisor and myself proceeded to make the appropriate phone calls to system control, maintenance control, lead captain etc.

Title: FLT CREW OF ACR TWI TURBOPROP EXPERIENCES MOMENTARY ENGINE OVERTEMP ON TAXI IN.

Narrative: THE TWR REQUESTED FLT TO EXIT AT TXWY ECHO AND PROCEED ACROSS 6 L AND TAXI VIA RAMP TO GATE. AFTER FULLY RETARDING THE THROTTLES (PWR LEVERS) AND WITH THE F/O RECEIVING TAXI INSTRUCTIONS FROM THE TWR, I TURNED TO TAXI UP TXWY ECHO, AT WHICH POINT I ADVANCED THE PWR LEVERS AND SAW A RAPID RISE AND A MOMENTARY OVERTEMP ON THE ENG TEMP GAUGES. AT THAT TIME I IMMEDIATELY CLOSED THE PWR LEVERS AND SELECTED GND FINE PITCH. THE TEMPS COOLED RAPIDLY AND WE TAXIED IN, W/O FURTHER INCIDENT. AFTER SHUTDOWN I PHYSICALLY PULLED THE PROPS THROUGH AND VISLY INSPECTED THE ENGS, SEEING NO OUTWARD SIGNS OF DAMAGE I WENT IMMEDIATELY TO THE MAINT SUPVR AND RPTED THE INCIDENT. BOTH THE SUPVR AND MYSELF PROCEEDED TO MAKE THE APPROPRIATE PHONE CALLS TO SYS CTL, MAINT CTL, LEAD CAPT ETC.
