Narrative:

On the arrival into clt at approximately 11000 ft, the preliminary landing check was accomplished during which the hydraulic pumps are placed to high from low setting. Approximately 2-3 mins later, the left hydraulic system pressure low light was noticed to illuminate. System pressure was 0 and quantity was empty. An emergency was declared and all emergency and normal checklists were completed. We requested some additional vectoring while the checklists were accomplished, talked to our company dispatcher, flight attendants were notified and the passenger were briefed of the situation. An ILS approach was flown to runway 36L. WX was 300 ft overcast 1 1/2 mi visibility, rain and fog. Approach and landing were normal during somewhat gusty wind conditions. Brakes were applied normally and, often slowing to a taxi speed, cleared the runway. Emergency was terminated and taxied to gate. Upon arrival at gate, the mechanic came up and said he observed the hydraulic fluid in right wheel well. He also informed us that the #3 tire (inboard on right side) was a recapped tire and the capping had separated from the tire and a piece had been thrown up into the trailing edge flaps on landing and some marks on the cowling of the right engine. Passenger were deplaned with no injuries. Supplemental information from acn 259469: as the passenger were beginning to disembark, a uniformed airport police officer, gun and all, appeared in our cockpit. The officer had a pad and pencil and was politely requesting information from us, including our names, bases, details of the system failure which caused us to declare an emergency, fuel on board, and other such questions. All of the rubber had separated from the tire. I walked back to the right engine and observed a few black marks on the inboard side, and I pointed this out to 1 of the mechanics, who had not noticed it yet. I think that after an airliner lands after having declared an emergency, the crew should not have to be faced with distrs such as armed officers in the cockpit and also 'urgent' messages to contact crew schedulers who are only interested in getting the crew onto another airplane.

Title: EMER DECLARED ON ACR MLG WITH LOSS OF ONE HYD SYS ON APCH IN A NIGHT OP. FO RPTS LEVELS OF NEAR HARASSMENT AT GATE.

Narrative: ON THE ARR INTO CLT AT APPROX 11000 FT, THE PRELIMINARY LNDG CHK WAS ACCOMPLISHED DURING WHICH THE HYD PUMPS ARE PLACED TO HIGH FROM LOW SETTING. APPROX 2-3 MINS LATER, THE L HYD SYS PRESSURE LOW LIGHT WAS NOTICED TO ILLUMINATE. SYS PRESSURE WAS 0 AND QUANTITY WAS EMPTY. AN EMER WAS DECLARED AND ALL EMER AND NORMAL CHKLISTS WERE COMPLETED. WE REQUESTED SOME ADDITIONAL VECTORING WHILE THE CHKLISTS WERE ACCOMPLISHED, TALKED TO OUR COMPANY DISPATCHER, FLT ATTENDANTS WERE NOTIFIED AND THE PAX WERE BRIEFED OF THE SIT. AN ILS APCH WAS FLOWN TO RWY 36L. WX WAS 300 FT OVCST 1 1/2 MI VISIBILITY, RAIN AND FOG. APCH AND LNDG WERE NORMAL DURING SOMEWHAT GUSTY WIND CONDITIONS. BRAKES WERE APPLIED NORMALLY AND, OFTEN SLOWING TO A TAXI SPD, CLRED THE RWY. EMER WAS TERMINATED AND TAXIED TO GATE. UPON ARR AT GATE, THE MECH CAME UP AND SAID HE OBSERVED THE HYD FLUID IN R WHEEL WELL. HE ALSO INFORMED US THAT THE #3 TIRE (INBOARD ON R SIDE) WAS A RECAPPED TIRE AND THE CAPPING HAD SEPARATED FROM THE TIRE AND A PIECE HAD BEEN THROWN UP INTO THE TRAILING EDGE FLAPS ON LNDG AND SOME MARKS ON THE COWLING OF THE R ENG. PAX WERE DEPLANED WITH NO INJURIES. SUPPLEMENTAL INFO FROM ACN 259469: AS THE PAX WERE BEGINNING TO DISEMBARK, A UNIFORMED ARPT POLICE OFFICER, GUN AND ALL, APPEARED IN OUR COCKPIT. THE OFFICER HAD A PAD AND PENCIL AND WAS POLITELY REQUESTING INFO FROM US, INCLUDING OUR NAMES, BASES, DETAILS OF THE SYS FAILURE WHICH CAUSED US TO DECLARE AN EMER, FUEL ON BOARD, AND OTHER SUCH QUESTIONS. ALL OF THE RUBBER HAD SEPARATED FROM THE TIRE. I WALKED BACK TO THE R ENG AND OBSERVED A FEW BLACK MARKS ON THE INBOARD SIDE, AND I POINTED THIS OUT TO 1 OF THE MECHS, WHO HAD NOT NOTICED IT YET. I THINK THAT AFTER AN AIRLINER LANDS AFTER HAVING DECLARED AN EMER, THE CREW SHOULD NOT HAVE TO BE FACED WITH DISTRS SUCH AS ARMED OFFICERS IN THE COCKPIT AND ALSO 'URGENT' MESSAGES TO CONTACT CREW SCHEDULERS WHO ARE ONLY INTERESTED IN GETTING THE CREW ONTO ANOTHER AIRPLANE.
