Narrative: I initially was the pilot flying. Passing through 10;000 FT I called for 'props 850; climb checklist below the line.' Shortly after that I noticed high oil temp on #1 engine. We immediately leveled off at 12;000 FT and notified ATC. The Captain pulled out the QRH and read it. I reduced the power 20% to about 68-70% torque. We started the clock for 10 minutes. Next we notified the flight attendants of a potential engine shut down. We tried to text Dispatch several times of the problem. For a while we had a VHF no comm. I tried to get Departure Operations and could not reach them. 10 minutes expired. We completed the QRH which led us to the engine shutdown QRH procedure. I disengaged the autopilot and we shut down the engine per Company procedures. The Captain declared an emergency. I turned the airplane back to the departure airport. We were given direct. Then we received a message saying to monitor the temperature for 2 minutes and it could be an indication failure. At that point we had already shut the engine down. The Captain made a PA. We swapped controls [and] then re-engaged autopilot. We asked for 15R. We were given direct the outer marker. I called the flight attendants and gave them the emergency brief. I told them we shut down the engine as a precaution; about 20-30 from landing; stay on the airplane do not evacuate after landing we will be towed to the gate; and no special bracing. We set up the approach and the Captain briefed it. We were given 10;000 FT. We descended; and completed single engine QRH descent and approach checklist. I used the FMS and sent the landing data and never got numbers back. We used the speed cards for 62;000 LBS. I sent a text message to Dispatch telling them we were using 15R; landing weight 61;500 with an LDF of 1.4. We got no response. I called Operations several times with no response. Then I heard another airplane call Operations with times and I asked them to relay the LDF 1.4 message and I got no response. Then we were given 4;000 FT. We descended. The Captain and I discussed that our normal landing distance is around 4;400 FT. With an LDF of 1.4 it is less than 7;500 FT. 15R is 10;000 FT long. We were within limits. Then given 3;000 FT; we descended. The Captain called for flaps 5. I put flaps 5. We want to blue needles. Localizer captured. I called 'runway in sight' and the Captain said 'landing.' Glide slope alive. The Captain disengaged the autopilot and called for gear down. Then he said flaps 15 single engine before landing checklist. I completed the checklist out loud with him. He followed the localizer and glide slope down and landed on the centerline. He exited the runway to the left. Then we completed the after landing and parking checklist [and] were towed to the gate.




Synopsis: After a Q400 #1 engine oil reached 124C the QRH directed an engine shutdown. An emergency was declared and the flight returned to the departure airport.
