Narrative:

ILS to runway 27R at mia flown with runway sighted near minimums in very heavy rain. Upon touchdown, rain intensity increased, visibility decreased, and crosswind component increased. Runway lights remained in view, but runway surface on approach end was completely covered by standing water of unknown depth. Aircraft was probably completely hydroplaning at this time. Aircraft drifted towards right runway edge lights but did not cross them. Taxi in and parking were normal except that mia tower and ground control requested verbal position reports. I infer from this that they were unable to see the runway and taxi route. Postflt inspection revealed a cut #4 main landing gear tire and muddy water and loose grass around right main landing gear area. A subsequent physical inspection after the rainstorm passed by airport personnel indicated no damage to any runway lights nor any evidence of a runway excursion.

Title: DC9-30 PARTIAL LOSS OF CTL LNDG MIA WITH POOR VISIBILITY AND ACFT HYDROPLANING.

Narrative: ILS TO RWY 27R AT MIA FLOWN WITH RWY SIGHTED NEAR MINIMUMS IN VERY HVY RAIN. UPON TOUCHDOWN, RAIN INTENSITY INCREASED, VISIBILITY DECREASED, AND XWIND COMPONENT INCREASED. RWY LIGHTS REMAINED IN VIEW, BUT RWY SURFACE ON APCH END WAS COMPLETELY COVERED BY STANDING WATER OF UNKNOWN DEPTH. ACFT WAS PROBABLY COMPLETELY HYDROPLANING AT THIS TIME. ACFT DRIFTED TOWARDS R RWY EDGE LIGHTS BUT DID NOT CROSS THEM. TAXI IN AND PARKING WERE NORMAL EXCEPT THAT MIA TWR AND GND CTL REQUESTED VERBAL POS RPTS. I INFER FROM THIS THAT THEY WERE UNABLE TO SEE THE RWY AND TAXI RTE. POSTFLT INSPECTION REVEALED A CUT #4 MAIN LNDG GEAR TIRE AND MUDDY WATER AND LOOSE GRASS AROUND R MAIN LNDG GEAR AREA. A SUBSEQUENT PHYSICAL INSPECTION AFTER THE RAINSTORM PASSED BY ARPT PERSONNEL INDICATED NO DAMAGE TO ANY RWY LIGHTS NOR ANY EVIDENCE OF A RWY EXCURSION.
