F-100 FLC EXPERIENCED HYD FAILURE DURING TKOF ROLL. FLC CONTINUED TKOF AND RETURN LAND. EMER DECLARED.

Narrative

DURING TKOF; AT APPROX 100 KTS; WE GOT A MASTER CAUTION WARNING LIGHT AND AURAL CHIME. WE CONTINUED THE TKOF. AFTER GETTING SAFELY AIRBORNE AND CLEANED UP; WE SAW A HYD SYS 1 FAIL MESSAGE ON THE MULTIFUNCTION DISPLAY UNIT. I (THE CAPT) WAS FLYING AT THE TIME AND I DIRECTED THE FO TO HANDLE THE PROC WHILE I FLEW THE AIRPLANE AND HANDLED THE RADIOS. I DECLARED AN EMER WITH APCH CTL AND REQUESTED THAT THE EQUIP BE STANDING BY. WE USED THE ALTERNATE FLAP AND GEAR EXTENSION. DUE TO THIS HYD LOSS; WE WERE LEFT WITHOUT THRUST REVERSERS AND NOSEWHEEL STEERING. DUE TO HAVING NO NOSEWHEEL STEERING; OUR FLT MANUAL RECOMMENDS THAT WE STOP STRAIGHT AHEAD ON THE RWY; SHUT DOWN THE ENGS AND BE TOWED OFF. DURING THE LNDG ROLLOUT; I CLRED THE RWY AT A HIGH SPD TXWY USING VERY LIGHT DIFFERENTIAL BRAKING AT A VERY LOW SPD. WE STOPPED ON THE HIGH SPD TXWY; SHUT DOWN THE ENGS AFTER MAINT PINNED OUR GEAR; AND WERE TOWED TO THE GATE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: ACFT IS A FOKKER 100 (FK10). RPTR STATES THAT ACFT WAS IN MAINT DURING THE NIGHT PRIOR TO THE TRIP. THE HYD SYS WAS THE SUBJECT OF THE MAINT ACTIVITY. AFTER DECLARING THE EMER; THE CAPT CALLED THE 'A' FLT ATTENDANT TO THE COCKPIT AND BRIEFED. PAX WERE TOLD THAT THEY WERE RETURNING TO LAND TO RESOLVE A HYD MALFUNCTION. AFTER LNDG; THE CAPT RELEASED THE CFR TEAM THROUGH GND CTL FREQ.
