PIC of a DO328 leveled off from descent and, as he added power for maintaining speed, he exceeded the manufacturer's recommended torque on both engines. Reporter cites concerns relative to thunderstorm activity in the tys area and was concentrating on his radar scope.

Narrative:
On flight from pit to tys I was the PF. At approximately XX00 EST we were issued a descent clearance from FL190 to 11000 ft MSL. As we leveled off at 11000 ft MSL I pushed the power levers forward to maintain airspeed. At the time I was concentrating on the WX radar to map a course to avoid level 3-5 thunderstorms. I then noticed the torque gauges in excess of the manufacture's limitations. I reduced power and landed without event. The aircraft engines required inspection and service before the aircraft was returned to service.

I THEN NOTICED THE TORQUE GAUGES IN EXCESS OF THE MANUFACTURE'S LIMITATIONS. I REDUCED PWR AND LANDED WITHOUT EVENT. THE ACFT ENGS REQUIRED INSPECTION AND SVC BEFORE THE ACFT WAS RETURNED TO SVC.
