Narrative:

On the above described flight, we lost hydraulic system 'a' pressure and fluid as the flaps were raised from 5 degrees to 2 degrees. After coordination with company dispatch, we diverted to jfk because the winds were more favorable, runway longer, response equipment better and aircraft weight would be below 150000 pounds. All of the appropriate checklists were accomplished (including alternate gear and flap extension) and an uneventful landing at jfk was accomplished. Callback conversation with reporter revealed the following information: reporter states he was the first officer on this flight and the aircraft was a B727- 200. The only details he can supply on what failed is a split hydraulic pressure line. He has no knowledge of what system the line was connected to or supplied.

Original NASA ASRS Text

Title: A B727-200 AFTER TKOF ON GEAR AND FLAP RETRACTION EXPERIENCED LOSS OF 'A' HYD SYS.

Narrative: ON THE ABOVE DESCRIBED FLT, WE LOST HYD SYS 'A' PRESSURE AND FLUID AS THE FLAPS WERE RAISED FROM 5 DEGS TO 2 DEGS. AFTER COORD WITH COMPANY DISPATCH, WE DIVERTED TO JFK BECAUSE THE WINDS WERE MORE FAVORABLE, RWY LONGER, RESPONSE EQUIP BETTER AND ACFT WT WOULD BE BELOW 150000 LBS. ALL OF THE APPROPRIATE CHKLISTS WERE ACCOMPLISHED (INCLUDING ALTERNATE GEAR AND FLAP EXTENSION) AND AN UNEVENTFUL LNDG AT JFK WAS ACCOMPLISHED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES HE WAS THE FO ON THIS FLT AND THE ACFT WAS A B727- 200. THE ONLY DETAILS HE CAN SUPPLY ON WHAT FAILED IS A SPLIT HYD PRESSURE LINE. HE HAS NO KNOWLEDGE OF WHAT SYS THE LINE WAS CONNECTED TO OR SUPPLIED.
