Narrative:
On approach into dca, we lowered the gear in preparation for landing. Upon lowering the gear, a loud noise was heard in the back of the plane and the hydraulic gauges were checked for any landing gear abnormalities. System a fluid quantity read 0 and company procedures were followed for the situation. The captain then decided to proceed to iad where we would have a longer runway. Crew and passenger were briefed on the possibility of an emergency evacuate/evacuation. A normal approach and landing was made to 1L, and an emergency evacuate/evacuation was not needed. The plane was brought to a stop and the passenger were deplaned.

Title: ACR LGT SUFFERS LOSS OF 'A' HYDRAULIC SYSTEM ON APCH TO DCA, DIVERTS TO IAD FOR LONGER RWY.
Narrative: ON APCH INTO DCA, WE LOWERED THE GEAR IN PREPARATION FOR LNDG. UPON LOWERING THE GEAR, A LOUD NOISE WAS HEARD IN THE BACK OF THE PLANE AND THE HYD GAUGES WERE CHKED FOR ANY LNDG GEAR ABNORMALITIES. SYS A FLUID QUANTITY READ 0 AND COMPANY PROCS WERE FOLLOWED FOR THE SITUATION. THE CAPT THEN DECIDED TO PROCEED TO IAD WHERE WE WOULD HAVE A LONGER RWY. CREW AND PAX WERE BRIEFED ON THE POSSIBILITY OF AN EMER EVAC. A NORMAL APCH AND LNDG WAS MADE TO 1L, AND AN EMER EVAC WAS NOT NEEDED. THE PLANE WAS BROUGHT TO A STOP AND THE PAX WERE DEPLANED.
