Narrative:

The bos ATIS indicated that the departure runway in use was runway 9. Our takeoff performance settings did not include runway 9 data. We pulled up runway 9 through ACARS on the FMS unit. Additionally, we set up the panel for a runway 9 departure. After pushout (52 mins late) we received taxi instructions for runway 9 and were told to monitor tower on 128.8 at taxiway B hold point. Tower then gave us taxi instructions for runway 4R and monitor 119.1. Just after the frequency change, tower issued taxi and hold orders for runway 4R. At this point, I was scrambling to uplink runway 4R takeoff data on the FMC, review the logan 2 departure, and get started on the before takeoff checklist. We thought everything was set prior to the takeoff. Evidently, we failed to notice or forgot about the 4 NM DME turn point for the 090 degree heading and initiated the turn about 2 NM too early. Obviously, we felt rushed and, in retrospect, should have asked for a few mins delay and reviewed a little more thoroughly.

Original NASA ASRS Text

Title: A B757-200 CREW TURNED EARLY ON A SID AFTER A LAST MIN RWY CHANGE AT BOS.

Narrative: THE BOS ATIS INDICATED THAT THE DEP RWY IN USE WAS RWY 9. OUR TKOF PERFORMANCE SETTINGS DID NOT INCLUDE RWY 9 DATA. WE PULLED UP RWY 9 THROUGH ACARS ON THE FMS UNIT. ADDITIONALLY, WE SET UP THE PANEL FOR A RWY 9 DEP. AFTER PUSHOUT (52 MINS LATE) WE RECEIVED TAXI INSTRUCTIONS FOR RWY 9 AND WERE TOLD TO MONITOR TWR ON 128.8 AT TXWY B HOLD POINT. TWR THEN GAVE US TAXI INSTRUCTIONS FOR RWY 4R AND MONITOR 119.1. JUST AFTER THE FREQ CHANGE, TWR ISSUED TAXI AND HOLD ORDERS FOR RWY 4R. AT THIS POINT, I WAS SCRAMBLING TO UPLINK RWY 4R TKOF DATA ON THE FMC, REVIEW THE LOGAN 2 DEP, AND GET STARTED ON THE BEFORE TKOF CHKLIST. WE THOUGHT EVERYTHING WAS SET PRIOR TO THE TKOF. EVIDENTLY, WE FAILED TO NOTICE OR FORGOT ABOUT THE 4 NM DME TURN POINT FOR THE 090 DEG HDG AND INITIATED THE TURN ABOUT 2 NM TOO EARLY. OBVIOUSLY, WE FELT RUSHED AND, IN RETROSPECT, SHOULD HAVE ASKED FOR A FEW MINS DELAY AND REVIEWED A LITTLE MORE THOROUGHLY.
