Narrative:

The captain made the approach and landing. All aom procedures for normal ILS, approach, landing and reverse thrust were followed, except #1 and #1 reverse were not used as #1 reverse was deactivated. The runway surface was set with patchy ice. Braking action reported good by tapely meter reading .77/.75/.75. After nose wheel touchdown, normal brakes were applied. On clearing the runway it was apparent to the crew that at least 1 tire was flat. Company maintenance confirmed that the 2 right aft tires were flat. The aircraft was not taxied after clearing the active runway until 1 tire was changed. Post shutdown inspection revealed reverted rubber hydroplaning on both tires.

Title: AN LGT FREIGHTER BLEW 2 TIRES ON LNDG IN HYDROPLANING AND ICY CONDITIONS.

Narrative: THE CAPT MADE THE APCH AND LNDG. ALL AOM PROCS FOR NORMAL ILS, APCH, LNDG AND REVERSE THRUST WERE FOLLOWED, EXCEPT #1 AND #1 REVERSE WERE NOT USED AS #1 REVERSE WAS DEACTIVATED. THE RWY SURFACE WAS SET WITH PATCHY ICE. BRAKING ACTION RPTED GOOD BY TAPELY METER READING .77/.75/.75. AFTER NOSE WHEEL TOUCHDOWN, NORMAL BRAKES WERE APPLIED. ON CLRING THE RWY IT WAS APPARENT TO THE CREW THAT AT LEAST 1 TIRE WAS FLAT. COMPANY MAINT CONFIRMED THAT THE 2 R AFT TIRES WERE FLAT. THE ACFT WAS NOT TAXIED AFTER CLRING THE ACTIVE RWY UNTIL 1 TIRE WAS CHANGED. POST SHUTDOWN INSPECTION REVEALED REVERTED RUBBER HYDROPLANING ON BOTH TIRES.
