Narrative:

Air carrier X was cleared to land on 26L while passing the OM. Air carrier Y seemed somewhat close ahead, so I slowed to approach speed early. Air carrier Y landed and continued to roll along. I requested confirmation from the copilot that we were cleared to land. He said, 'yes.' no other instructions or cautions were issued by the tower. I had expected air carrier Y to clear at any moment--he did not. I landed while the other aircraft was at the far end of 26L. Supplemental information from acn 169622: approximately 3 mi north trail of another aircraft for the same runway, there were also aircraft on visibility approachs to runway 26R and 25. We switched over to the tower controller and were cleared to land on 26L with no mention of the aircraft ahead. We executed a normal approach and landing with no incident. On landing the preceding aircraft was still on the active runway, as it had failed to make one of the earlier turnoffs and was in the process of clearing as we landed. Also just prior to our arrival the tower controller had the aircraft that was approaching runway 25 execute a missed approach due to an aircraft on runway 25. I feel a serious lapse of safety occurred due to: tightness of arrival spacing on visibility approachs west/O regard to different aircraft approach speeds, 3 aircraft approaching and landing together on runways 26L, 26R and 25, the tower controller being distracted by having to order aircraft on approach to runway 25 to execute a missed approach, failure of landing aircraft to exit runway quickly, and heavy controller workload.

Title: ACR X LANDED ON OCCUPIED RWY HAD LESS THAN STANDARD SEPARATION FROM ACR Y. OPERATIONAL DEVIATION. SYSTEM ERROR.

Narrative: ACR X WAS CLRED TO LAND ON 26L WHILE PASSING THE OM. ACR Y SEEMED SOMEWHAT CLOSE AHEAD, SO I SLOWED TO APCH SPD EARLY. ACR Y LANDED AND CONTINUED TO ROLL ALONG. I REQUESTED CONFIRMATION FROM THE COPLT THAT WE WERE CLRED TO LAND. HE SAID, 'YES.' NO OTHER INSTRUCTIONS OR CAUTIONS WERE ISSUED BY THE TWR. I HAD EXPECTED ACR Y TO CLR AT ANY MOMENT--HE DID NOT. I LANDED WHILE THE OTHER ACFT WAS AT THE FAR END OF 26L. SUPPLEMENTAL INFO FROM ACN 169622: APPROX 3 MI N TRAIL OF ANOTHER ACFT FOR THE SAME RWY, THERE WERE ALSO ACFT ON VIS APCHS TO RWY 26R AND 25. WE SWITCHED OVER TO THE TWR CTLR AND WERE CLRED TO LAND ON 26L WITH NO MENTION OF THE ACFT AHEAD. WE EXECUTED A NORMAL APCH AND LNDG WITH NO INCIDENT. ON LNDG THE PRECEDING ACFT WAS STILL ON THE ACTIVE RWY, AS IT HAD FAILED TO MAKE ONE OF THE EARLIER TURNOFFS AND WAS IN THE PROCESS OF CLRING AS WE LANDED. ALSO JUST PRIOR TO OUR ARR THE TWR CTLR HAD THE ACFT THAT WAS APCHING RWY 25 EXECUTE A MISSED APCH DUE TO AN ACFT ON RWY 25. I FEEL A SERIOUS LAPSE OF SAFETY OCCURRED DUE TO: TIGHTNESS OF ARR SPACING ON VIS APCHS W/O REGARD TO DIFFERENT ACFT APCH SPDS, 3 ACFT APCHING AND LNDG TOGETHER ON RWYS 26L, 26R AND 25, THE TWR CTLR BEING DISTRACTED BY HAVING TO ORDER ACFT ON APCH TO RWY 25 TO EXECUTE A MISSED APCH, FAILURE OF LNDG ACFT TO EXIT RWY QUICKLY, AND HEAVY CTLR WORKLOAD.
