I was departing the runway with a student for training purposes. The preflight and run up of the aircraft checked out fine, indicating no problems. After takeoff while turning crosswind there was a sudden power loss and the engine operation became very rough. I immediately applied carburetor heat and turned inbound for the runway. I did not deem that it was safe to try to continue the traffic pattern at the present altitude and engine condition. I declared engine problems and an emergency landing to ATC. While I turned inbound I was cleared to land on any available surface. I made the landing on 19L, the same runway I departed. The engine ran poorly after landing also. I proceeded to the run up area and did another thorough run up. The roughness smoothes out. After everything checked out, I departed the airport and went to the practice area. The aircraft ran fine after the one incident. After some maneuvers and several takeoffs and lndgs, I brought the aircraft back in and landed it. The tower called and wanted me to contact them by phone after shutdown. After shutdown I called the tower and was told to contact a person at FSDO. I turn I called him and gave a description of the situation. The mechanic at the company that I work for and I determined that the problem was that the engine had gotten some water in its system causing the initial power loss. No water contamination had shown during the preflight, though. I deem that I acted accordingly and promptly to the situation, west/O putting any person or properly or the aircraft in danger. I departed 1R and made the emergency landing on 19L at the fairbanks international airport.

Title: ACFT EXPERIENCED A ROUGH RUNNING ENGINE AND SOME POWER LOSS IMMEDIATELY AFTER TKOF. REPORTER IMMEDIATELY RETURNED TO THE DEP ARPT AND LANDED.
Narrative: I WAS DEPARTING THE RWY WITH A STUDENT FOR TRNING PURPOSES. THE PREFLT AND RUN UP OF THE ACFT CHKED OUT FINE, INDICATING NO PROBS. AFTER TKOF WHILE TURNING XWIND THERE WAS A SUDDEN PWR LOSS AND THE ENG OPERATION BECAME VERY ROUGH. I IMMEDIATELY APPLIED CARB HEAT AND TURNED INBND FOR THE RWY. I DID NOT DEEM THAT IT WAS SAFE TO TRY TO CONTINUE THE TFC PATTERN AT THE PRESENT ALT AND ENG CONDITION. I DECLARED ENG PROBS AND AN EMER LNDG TO ATC. WHILE I TURNED INBND I WAS CLRED TO LAND ON ANY AVAILABLE SURFACE. I MADE THE LNDG ON 19L, THE SAME RWY I DEPARTED. THE ENG RAN POORLY AFTER LNDG ALSO. I PROCEEDED TO THE RUN UP AREA AND DID ANOTHER THOROUGH RUN UP. THE ROUGHNESS SMOOTHES OUT. AFTER EVERYTHING CHKED OUT, I DEPARTED THE ARPT AND WENT TO THE PRACTICE AREA. THE ACFT RAN FINE AFTER THE ONE INCIDENT. AFTER SOME MANEUVERS AND SEVERAL TKOFS AND LNDGS, I BROUGHT THE ACFT BACK IN AND LANDED IT. THE TWR CALLED AND WANTED ME TO CONTACT THEM BY PHONE AFTER SHUTDOWN. AFTER SHUTDOWN I CALLED THE TWR AND WAS TOLD TO CONTACT A PERSON AT FSDO. I TURN I CALLED HIM AND GAVE A DESCRIPTION OF THE SITUATION. THE MECH AT THE COMPANY THAT I WORK FOR AND I DETERMINED THAT THE PROB WAS THAT THE ENG HAD GOTTEN SOME WATER IN ITS SYS CAUSING THE INITIAL PWR LOSS. NO WATER CONTAMINATION HAD SHOWN DURING THE PREFLT, THOUGH. I DEEM THAT I ACTED ACCORDINGLY AND PROMPTLY TO THE SITUATION, W/O PUTTING ANY PERSON OR PROPERLY OR THE ACFT IN DANGER. I DEPARTED 1R AND MADE THE EMER LNDG ON 19L AT THE FAIRBANKS INTL ARPT.
