During the takeoff the Captain proceeded to place the power levers to the power set notch. We observed normal indications on the engine instruments. As we continued the takeoff roll the Number 2 Engine torque began to rise above 90%. Reaching 95% the Captain pulled the Number 2 Engine power lever back below the power lever notch. With the Number 2 power lever below the notch I observed the Number 2 engine ITT reach 775 degrees and called for 'Aborted Takeoff'. The Captain decided to abort the takeoff. Once slowed to a normal taxi speed while still on the runway we got a momentary flash of low oil pressure on the CAP and low oil pressure light on the Number 2 Engine oil gauge. The Captain decided to shut the Number 2 Engine down. When the Captain brought the Number 2 condition lever to feather a scraping noise could be heard coming from the Number 2 Engine. On the post flight inspection I found that the Number 2 Engine propeller would not rotate. The Captain proceeded to call Maintenance Control and reported the discrepancy.
When we got cleared for takeoff; I proceeded to place the power levers to the power set notch. I observed normal indications on the engine instruments. As we continued on the takeoff roll the Number 2 Engine torque began to rise above 90% torque. Reaching 95% torque I reduced the Number 2 power lever below the power set notch. With the power lever below the power set notch I noticed the Number 2 Engine ITT was at 775 degrees Celsius. I decided to abort the takeoff. Once slowed to normal taxi speed while still on the runway I got a momentary flash of low oil pressure on the CAP and low oil pressure light on the Number 2 Engine oil gauge. I decided to shut the Number 2 Engine down. When I brought the Number 2 condition lever to feather a scraping noise could be heard coming from the Number 2 Engine. When I placed the Number 2 condition lever to fuel shut off I noticed the propeller came to a sudden stop. On the post flight inspection I found the Number 2 engine propeller would not rotate. I proceeded to call Maintenance Control and reported the discrepancy.
An ATR-72 Captain rejected the takeoff when he detected the number two engine beginning to over torque. During the reject they shut the engine down when the low oil pressure illuminated as the engine seized.
