Narrative:

I was the captain and PF on air carrier X flight abcd. Started our takeoff roll on runway 4L. At approximately 60 KTS, the first officer's cockpit window opened. I immediately aborted the takeoff and notified jfk tower. As we taxied back to ramp, company was notified. Also, logbook entry was made. Maintenance inspected first officer's cockpit window. Maintenance wrote off logbook discrepancy as cockpit window working properly. Prior to this incident, all company procedures and checklists were followed. One item on the checklist is 'doors/cockpit windows...closed/locked.' the response is to be made by both pilots. I always ensure the captain's cockpit window is closed/locked by doing a push/pull motion on the handle of the captain's cockpit window. The first officer's cockpit window was prior to responding to it being 'closed/locked.' he stated that he 'pushed' the handle of the cockpit window. When maintenance asked him to try it again, and then he 'pulled' on the handle, the first officer's cockpit window opened. Corrective actions: a push/pull method should be used to ensure the cockpit window is closed/locked. If the window opens when you pull the handle, 1) close the window, 2) push the handle to lock the window, and 3) pull the handle to ensure the cockpit window is closed/locked.

Narrative: I WAS THE CAPT AND PF ON ACR X FLT ABCD. STARTED OUR TKOF ROLL ON RWY 4L. AT APPROX 60 KTS, THE FO'S COCKPIT WINDOW OPENED. I IMMEDIATELY ABORTED THE TKOF AND NOTIFIED JFK TWR. AS WE TAXIED BACK TO RAMP, COMPANY WAS NOTIFIED. ALSO, LOGBOOK ENTRY WAS MADE. MAINT INSPECTED FO'S COCKPIT WINDOW. MAINT WROTE OFF LOGBOOK DISCREPANCY AS COCKPIT WINDOW WORKING PROPERLY. PRIOR TO THIS INCIDENT, ALL COMPANY PROCS AND CHKLISTS WERE FOLLOWED. ONE ITEM ON THE CHKLIST IS 'DOORS/COCKPIT WINDOWS...CLOSED/LOCKED.' THE RESPONSE IS TO BE MADE BY BOTH PLTS. I ALWAYS ENSURE THE CAPT'S COCKPIT WINDOW IS CLOSED/LOCKED BY DOING A PUSH/PULL MOTION ON THE HANDLE OF THE CAPT'S COCKPIT WINDOW. THE FO'S COCKPIT WINDOW WAS PRIOR TO RESPONDING TO IT BEING 'CLOSED/LOCKED.' HE STATED THAT HE 'PUSHED' THE HANDLE OF THE COCKPIT WINDOW. WHEN MAINT ASKED HIM TO TRY IT AGAIN, AND THEN HE 'PULLED' ON THE HANDLE, THE FO'S COCKPIT WINDOW OPENED. CORRECTIVE ACTIONS: A PUSH/PULL METHOD SHOULD BE USED TO ENSURE THE COCKPIT WINDOW IS CLOSED/LOCKED.
