Narrative:

Moderate turbulence below FL220 on arrival to den area. Long final at centennial for ILS to the right runway. Cleared to land over the OM. At approximately 100-200 ft AGL, I thought I might have seen something on the runway but it seemed to disappear. I landed the aircraft and planned to exit approximately 7000-8000 ft down the runway. As I progressed down the runway I saw the single engine cessna turning off about 5000 ft beyond me. I exited the runway about 4000 ft prior to him. Nothing was ever said between any ATC facility and either aircraft. I should have questioned ATC about what I thought I might have seen but at 100 ft the only way to do this would have been to go around. I was not excited about the possibility of another long approach in moderate turbulence. ATC was obviously aware there would be a conflict but not a word was ever spoken either before or after the event. We all waited and hoped a little too long instead of taking decisive action.

Title: A PIPER CHEYENNE PLT LANDS ON AN OCCUPIED RWY AT CENTENNIAL ARPT WITHOUT ANY ADVISORY BY THE TWR CTLR.

Narrative: MODERATE TURB BELOW FL220 ON ARR TO DEN AREA. LONG FINAL AT CENTENNIAL FOR ILS TO THE R RWY. CLRED TO LAND OVER THE OM. AT APPROX 100-200 FT AGL, I THOUGHT I MIGHT HAVE SEEN SOMETHING ON THE RWY BUT IT SEEMED TO DISAPPEAR. I LANDED THE ACFT AND PLANNED TO EXIT APPROX 7000-8000 FT DOWN THE RWY. AS I PROGRESSED DOWN THE RWY I SAW THE SINGLE ENG CESSNA TURNING OFF ABOUT 5000 FT BEYOND ME. I EXITED THE RWY ABOUT 4000 FT PRIOR TO HIM. NOTHING WAS EVER SAID BTWN ANY ATC FACILITY AND EITHER ACFT. I SHOULD HAVE QUESTIONED ATC ABOUT WHAT I THOUGHT I MIGHT HAVE SEEN BUT AT 100 FT THE ONLY WAY TO DO THIS WOULD HAVE BEEN TO GO AROUND. I WAS NOT EXCITED ABOUT THE POSSIBILITY OF ANOTHER LONG APCH IN MODERATE TURB. ATC WAS OBVIOUSLY AWARE THERE WOULD BE A CONFLICT BUT NOT A WORD WAS EVER SPOKEN EITHER BEFORE OR AFTER THE EVENT. WE ALL WAITED AND HOPED A LITTLE TOO LONG INSTEAD OF TAKING DECISIVE ACTION.
