A BA3201 FLT LOSES ITS HYD SYS AND HAS TO MAKE AN EMER; 0 DEG FLAP LNDG AT IAD. ACFT LEFT TO MAINT ON THE RWY.

Narrative

I WAS ACTING AS PIC OF FLT IAD-BUF ON JAN/XA/98. I WAS IN THE R SEAT COMPLETING CAPT IOE ON MR X; STUDENT CAPT; AND WAS THE PF FROM BUF-IAD. AS WE WERE IN CRUISE; MY FLYING PARTNER NOTICED THE FLAPS WERE INDICATING 10 DEGS. WE HAD ALREADY COMPLETED THE AFTER TKOF AND THE CRUISE CHKLISTS SO THE INDICATION WAS ABNORMAL. I ASKED AT WHAT POS THE FLAP HANDLE WAS IN AND HE STATED IT WAS IN THE FLAPS 0 POS; NORMAL FOR CRUISE. I TOOK THE ATC RADIO; CONTINUED FLYING THE ACFT AND ASKED HIM TO CHK THE FLAP CTL CIRCUIT BREAKER WHILE I SLOWED BELOW 170 KTS. I ADVISED ATC (ZNY 134.8) OF OUR REDUCED SPD AND REQUESTED A DSCNT TO 15000 FT AND WAS GRANTED BOTH WITHOUT ANY FURTHER COM. MR X CHKED THE CIRCUIT BREAKER AND NOTICED IT WAS NOT TRIPPED. I THEN EXCHANGED CTL WITH HIM AND CHKED THE FLAP INDICATOR/OXYGEN BREAKER ON THE MAIN CIRCUIT BREAKER PANEL AND NOTICED IT TOO WAS NOT TRIPPED. WE THEN CONTACTED MAINT CTL VIA ARINC AND CONFERRED WITH THEM ABOUT OUR SIT AND THEY SUGGESTED WE CONTINUE TO DULLES. I ELECTED; SINCE THERE IS NO QRH PROC; TO ATTEMPT TO CYCLE THE FLAPS FROM THE 0-10 DEG POS. WHILE I FLEW THE ACFT; MR X SELECTED THE FLAP HANDLE FROM 0-10 AND NO INDICATION ON THE HYD PANEL OR NO CHANGE IN AERODYNAMIC FEEL WAS NOTED. WE THEN; AS A CREW; DECIDED THE BEST COURSE OF ACTION WOULD BE TO APCH AND LAND AT DULLES WITH 0 DEG FLAPS. I HAD MR X FLY THE ACFT WHILE I INFORMED DISPATCH AND MAINT; AS WELL AS DULLES OPS OF OUR INTENTIONS. I RECEIVED A CALL FROM DISPATCH THAT STATED THERE WAS 'NO PENALTY' FOR A 0 DEG FLAP LNDG AT DULLES ON ANY RWY. BY THIS TIME WE WERE CLOSE TO LNDG AT DULLES AND DECIDED IT BEST TO ATTEMPT TO PLACE THE LNDG GEAR DOWN TO SEE IF WE WOULD NEED TO PUMP THE LNDG GEAR DOWN UNDER THE EMER GEAR EXTENSION. THE LNDG GEAR LOWERED NORMALLY; YET DURING THE EXTENSION; THE HYD PANEL SHOWED BOTH L AND R PUMPS TO RUN CONTINUOUSLY AFTER WE RECEIVED 3 GREEN LIGHTS IN THE COCKPIT. WE THEN COMPLETED THE LOSS OF HYD; 0 DEG FLAP LNDG; LOSS OF NORMAL BRAKING PRESSURE AND THE NORMAL DSCNT AND APCH CHKLISTS AND TOLD THE CUSTOMERS AS WELL AS DULLES APCH THAT WE WOULD INDEED SHUT DOWN ON THE RWY. AFTER BEING CLRED FOR THE VISUAL APCH TO RWY 19L AND THEN CLRED TO LAND; WE STOPPED THE ACFT USING THE RESIDUAL HYD PRESSURE IN THE ACCUMULATOR AND COMPLETED THE AFTER LNDG AND SHUTDOWN CHKLISTS THEN DEPLANED THE CUSTOMERS VIA THE MAIN CABIN DOOR. A POSTFLT INSPECTION BY ME REVEALED THE FLAPS TO BE IN THE 0 DEG POS AND A LARGE QUANTITY OF HYD FLUID STREAKED FROM THE R TRAILING EDGE OF THE WING; INBOARD OF THE ENG NACELLE OVER THE REMAINDER OF THE R REAR FUSELAGE.
