Narrative:

Shortly after pushback started, the tug operator stopped and said we had new paperwork coming from operations. A baggage loader was brought up to the captain's window and a new automated weight and balance was given to the crew. The window was closed and the aircraft was taxied out for takeoff. The takeoff roll was normal and all indicators were normal. At about 80 KTS the captain's window slid slightly open. The captain made 1 attempt to close the window but was not successful. The captain then elected to reject the takeoff. Aircraft speed was 110 KTS. The aircraft was stopped on the runway uneventfully. The captain's window was then closed and locked and a PA was made to the passenger explaining what had occurred. The brake cooling chart was consulted and complied with. The senior flight attendant was consulted and she informed the captain that a female passenger was upset and wished to return to the gate and deplane. The aircraft was returned to the gate, refueled, received new paperwork and continued the flight uneventfully. Since it is not normal for a window to start to open if it is 'closed and locked' it is felt that the window probably was not completely 'locked' after the unusual event of passing new paperwork to the captain.

Original NASA ASRS Text

Title: AN ACR LGT ABORTED ITS TKOF WHEN THE CAPT'S SLIDING WINDOW CAME OPEN.

Narrative: SHORTLY AFTER PUSHBACK STARTED, THE TUG OPERATOR STOPPED AND SAID WE HAD NEW PAPERWORK COMING FROM OPS. A BAGGAGE LOADER WAS BROUGHT UP TO THE CAPT'S WINDOW AND A NEW AUTOMATED WT AND BAL WAS GIVEN TO THE CREW. THE WINDOW WAS CLOSED AND THE ACFT WAS TAXIED OUT FOR TKOF. THE TKOF ROLL WAS NORMAL AND ALL INDICATORS WERE NORMAL. AT ABOUT 80 KTS THE CAPT'S WINDOW SLID SLIGHTLY OPEN. THE CAPT MADE 1 ATTEMPT TO CLOSE THE WINDOW BUT WAS NOT SUCCESSFUL. THE CAPT THEN ELECTED TO REJECT THE TKOF. ACFT SPD WAS 110 KTS. THE ACFT WAS STOPPED ON THE RWY UNEVENTFULLY. THE CAPT'S WINDOW WAS THEN CLOSED AND LOCKED AND A PA WAS MADE TO THE PAX EXPLAINING WHAT HAD OCCURRED. THE BRAKE COOLING CHART WAS CONSULTED AND COMPLIED WITH. THE SENIOR FLT ATTENDANT WAS CONSULTED AND SHE INFORMED THE CAPT THAT A FEMALE PAX WAS UPSET AND WISHED TO RETURN TO THE GATE AND DEPLANE. THE ACFT WAS RETURNED TO THE GATE, REFUELED, RECEIVED NEW PAPERWORK AND CONTINUED THE FLT UNEVENTFULLY. SINCE IT IS NOT NORMAL FOR A WINDOW TO START TO OPEN IF IT IS 'CLOSED AND LOCKED' IT IS FELT THAT THE WINDOW PROBABLY WAS NOT COMPLETELY 'LOCKED' AFTER THE UNUSUAL EVENT OF PASSING NEW PAPERWORK TO THE CAPT.
