Narrative:
On our flight from ege to atl we experienced a left hydraulic system failure with a complete loss of fluid from the left system. An emergency was declared upon our arrival in the atlanta area. Due to our hydraulic problems an extra long final approach was flown to give us time to lower the landing gear and flaps using our alternate system. An uneventful approach and landing was accomplished with the aircraft being towed to the gate. Callback conversation with reporter revealed the following information: the reporter stated the cause of the left hydraulic system failure is unknown as maintenance has not reported what component failed and maintenance action taken.

Narrative: ON OUR FLT FROM EGE TO ATL WE EXPERIENCED A L HYD SYS FAILURE WITH A COMPLETE LOSS OF FLUID FROM THE L SYS. AN EMER WAS DECLARED UPON OUR ARR IN THE ATLANTA AREA. DUE TO OUR HYD PROBS AN EXTRA LONG FINAL APCH WAS FLOWN TO GIVE US TIME TO LOWER THE LNDG GEAR AND FLAPS USING OUR ALTERNATE SYS. AN UNEVENTFUL APCH AND LNDG WAS ACCOMPLISHED WITH THE ACFT BEING TOWED TO THE GATE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE CAUSE OF THE L HYD SYS FAILURE IS UNKNOWN AS MAINT HAS NOT RPTED WHAT COMPONENT FAILED AND MAINT ACTION TAKEN.
