Narrative:
During climbout just before reaching 16;000 ft; I noticed the right prop RPM gauge was fluctuating. I brought it to the captains attention and we noticed it was fluctuating between 1230 and 1270 but all other gauges were normal at this time. At 16;000 ft; the fluctuation was increasing and getting more consistent. The captain then called for the emergency/non-normal engines checklist. We then started to hear a sound difference in the right prop. We then noticed that the torque gauge was now fluctuating and I then turned to the erratic engine checklist. Just then the itt spiked to 1004 degrees and the over temp light came on. At that point the captain decided to shutdown the right engine due to the excessive temperature and called for the engine shutdown checklist. As I began the checklist; the captain asked for direct the previously departed station and told ATC to stand by. The captain then started the turn and while in the turn we reduced the power back to 20 -30 percent. He then told me to wait on the condition lever until we were finished with the turn so that we were at level flight. The over temperature light was still illuminated at this time. After the level out; he confirmed the right condition lever to fuel off and I then proceeded with the remainder of the checklist. The captain took control of the radios; gave the proper information to ATC then spoke to the flight attendant; then made a PA to the passengers. Once the checklist was finished; the captain gave me control of the radios and he then tried to contact dispatch with no success. He then called operations to tell them the situation and to have them tell dispatch to try and contact us. We then proceeded to the airport. The captain then performed a visual approach to runway 7. Emergency equipment was on the field waiting for us. The captain landed the airplane and we taxied to the gate and shutdown the airplane. Due to the fluctuations in prop RPM and torque; followed by itt temperatures that were out of normal limits; the captain decided to shut down the right engine.
