B727 LNDS IN RAIN SHOWER; HYDROPLANES TO DRY SURFACE WHERE ALL FOUR MAIN TIRES FAILED. RPTR COMPLAINS OF NUMEROUS ARPT HAZARDS AND PROBS.

Narrative

FLT WAS DISPATCHED WITH THE DESTINATION ARPT METAR WX 360/06KTS 7 SM OVC006 19/13 A3010. THE DESTINATION HAS NO TAF RPTING: FORECAST WEATHER FROM ANOTHER ARPT 60 MI TO THE E IS USED AND THIS SAME ARPT WAS DESIGNATED AS THE ALTERNATE FOR THIS LEG. APCHING THE TERMINAL AREA CB BUILDUPS WERE PRESENT NECESSITATING DEVIATION. FROM THE TONE OF THE OPS IT WAS EVIDENT CTLR WORK LOAD WAS HIGH. THE ATIS FOR THE DESTINATION ARPT RPTED SPECI 350/10KT 4-RBR BKN005 OVC015 18/13. THE REGULAR OBSERVATION APPROX TWENTY FIVE MINS LATER WAS 010/12KT 5 TS-RBR BKN005 OVC015 18/12. OUR WX RADAR SHOWED THE THUNDERSTORM ACTIVITY TO BE WELL BEYOND THE CONFINES OF THE ARPT BUT AT SEVENTEEN MI THE FLT ENGINEER WAS INSTRUCTED TO CONTACT THE TWR FOR THE LATEST RPT. THIS COM LINK WAS KEPT UNTIL WE WERE HANDED TO THE TWR. DUE TO THE AFOREMENTIONED THUNDERSTORM ACTIVITY A REQUEST WAS MADE FOR A NON-STD MISSED APCHED PROCEDURE. DURING THE ILS APCH AND WELL INSIDE THE FAF WE RECEIVED THE RPT OF RAIN MOVING ACROSS THE ARPT BUT ALL CREWMEMBERS NEVER HAD THE REALIZATION THAT IT COULD BE EXTREMELY HVY. THE ARPT WAS ACTUALLY SIGHTED AT THE EXPECTED 500 AGL WITH NO OBSCURATION OF VISIBILITY BTWN THE ACFT AND THE RWY ENVIRONMENT. DURING THE FLARE AND TOUCHDOWN THE RAIN BECAME HVY WITH VISIBILITY GREATLY REDUCED: THE THRUST WAS AT IDLE AND THE ACFT WAS COMMITTED TO LNDG. THE ACFT WHEELS HYDROPLANED WITH MAXIMUM BRAKING AND REVERSE THRUST APPLIED UNTIL A DRIER PORTION OF THE RWY WAS REACHED WHERE ALL FOUR TIRES DEFLATED. THIS IS AN OLDER ARPT THAT HAS RECENTLY BURGEONED INTO A FAR 121 DESTINATION BUT HAS SHORT RWYS; LIMITED WX RPTING CAPABILITY AND A VERY SERIOUS OBSTACLE AT THE DEP OF THE MAIN INSTRUMENT APCH. THE RECIPROCAL RWY HAS NO INSTRUMENT APCH; NECESSITATING A 1000 AND 3 MI; VFR CIRCLING MANEUVER ONLY MAKING THIS AN EXTREMELY DANGEROUS ENVIRONMENT. THESE FACTS COMBINED WITH ANOTHER THAT THIS MODEL TRANSPORT HAD THE MANDATED NOISE STC MODIFICATION INSTALLED THAT GREATLY REDUCES ITS STOPPING CAPABILITY. ARPT MGMNT HAS PLANS TO REMOVE THE OBSTACLE; EXTEND THE RWY AND ADD ANOTHER ILS BUT ENVIRONMENTAL CONCERNS ARE A FACTOR. IN THE INTEREST OF AVIATION SAFETY EXPEDITED HANDLING OF THE PERMITTING PROCESS SHOULD BE GIVEN. EVEN THOUGHT IT IS A SMALL; UNDERUTILIZED ARPT ITS DEFICIENCIES COULD BE GREATLY AUGMENTED WITH ALL OF THE LATEST TECHNOLOGY WEATHER RPTING EQUIP SUCH AS DOPPLER RADAR AND WIND SHEAR DETECTION. THE SIMPLE INSTALLATION OF RWY VISUAL RANGE EQUIP WOULD HAVE MOST ASSUREDLY MEANT THAT WE WOULD HAVE DETECTED THE IMPENDING LOWER VISIBILITY. CALLBACK CONVERSATION WITH THE RPTR REVEALED THE FOLLOWING INFO: RPTR SAID THAT THE REPORTED SHOWER PASSING OVER THE ARPT WAS NOT NOTED AS HVY AND NOW IN VISUAL CONDITIONS HE ELECTED TO CONTINUE AND LND. FINDING HVY RAIN AND WATER ON THE RWY AT TOUCHDOWN HE USED MAXIMUM BRAKING TO ALLOW ANTI SKID TO DO ITS JOB. THIS MODEL ACFT DOES NOT HAVE LOCKED WHEEL PROTECTION AND APPARENTLY THE WHEELS NEVER BEGAN TO TURN RESULTING IN HYDROPLANING TO THE DRY END OF THE RWY AND THE FAILED FOUR MAIN TIRES. THERE MAY BE THE POSSIBILITY BECAUSE OF THE SHOWER THAT THERE WAS A SLIGHT TAILWIND THAT WAS NOT RPTED. LNDG ROLL ENDED 1300 FT FROM THE END OF THE RWY WHICH ALLOWED THE INTERSECTING RWY TO REMAIN OPEN.
