Narrative:

During descent, first officer noticed abnormal hydraulic pressure on #2 pump. Captain was notified and within 10 seconds both crew observed total loss of hydraulic pressure. Crew confirmed pressure indications by listening to pumps cavitate. Crew consulted QRH and performed required actions. ATC was notified of aircraft status and emergency was declared. Crew decided to land into wind (opposite to direction of traffic pattern in use) due to loss of nosewheel steering and normal brakes. Delay vectors were requested so that crew had time to assess situation and make decisions. Passenger were briefed that gear would be lowered by emergency extension. Subsequent visual approach to runway 18L was uneventful and directional control was maintained easily through rudder, differential reverse thrust and braking. Aircraft was then shut down on runway and passenger exited under supervision of firemen and airport authority/authorized. Crew worked well as team (bounced ideas off each other) and performance of crew duties was positively effected by being able to discuss/suggest procedures. First officer recently attended company cockpit resource management course which helped ensure safe outcome.

Original NASA ASRS Text

Title: LTT LOSES ENTIRE HYD SYS.

Narrative: DURING DSCNT, FO NOTICED ABNORMAL HYD PRESSURE ON #2 PUMP. CAPT WAS NOTIFIED AND WITHIN 10 SECONDS BOTH CREW OBSERVED TOTAL LOSS OF HYD PRESSURE. CREW CONFIRMED PRESSURE INDICATIONS BY LISTENING TO PUMPS CAVITATE. CREW CONSULTED QRH AND PERFORMED REQUIRED ACTIONS. ATC WAS NOTIFIED OF ACFT STATUS AND EMER WAS DECLARED. CREW DECIDED TO LAND INTO WIND (OPPOSITE TO DIRECTION OF TFC PATTERN IN USE) DUE TO LOSS OF NOSEWHEEL STEERING AND NORMAL BRAKES. DELAY VECTORS WERE REQUESTED SO THAT CREW HAD TIME TO ASSESS SIT AND MAKE DECISIONS. PAX WERE BRIEFED THAT GEAR WOULD BE LOWERED BY EMER EXTENSION. SUBSEQUENT VISUAL APCH TO RWY 18L WAS UNEVENTFUL AND DIRECTIONAL CTL WAS MAINTAINED EASILY THROUGH RUDDER, DIFFERENTIAL REVERSE THRUST AND BRAKING. ACFT WAS THEN SHUT DOWN ON RWY AND PAX EXITED UNDER SUPERVISION OF FIREMEN AND ARPT AUTH. CREW WORKED WELL AS TEAM (BOUNCED IDEAS OFF EACH OTHER) AND PERFORMANCE OF CREW DUTIES WAS POSITIVELY EFFECTED BY BEING ABLE TO DISCUSS/SUGGEST PROCS. FO RECENTLY ATTENDED COMPANY COCKPIT RESOURCE MGMNT COURSE WHICH HELPED ENSURE SAFE OUTCOME.
