Narrative:

On takeoff roll at approximately 90-100 KIAS, captain tapped with fingers on oil pressure gauge for #2 engine and called 'reject the takeoff,' and pulled throttles to idle power. I initiated reverse thrust and manually extended speed brakes and felt onset of automatic antiskid rejected takeoff braking. Coordination with tower, flight attendants, passenger and company operations were completed in a timely manner and we were inspected and released by our maintenance personnel. I inquired of the captain if we should get a re-release from our dispatchers to continue. He stated to me it was not required and to continue with a checklist prior to start. We continued the flight to destination uneventfully under the original flight number, release, flight plan, and a revised weight and balance. Reviewing flight operations manual dated dec/xx/96, the captain and dispatcher must agree on the terms of release for the flight. I questioned the captain for a new release believing our dispatch time had elapsed and continue to believe a new release time should have been obtained. Since the item was a 'paper legality item' and not an immediate threat to flight safety, I followed the captain's direction and proceeded with checklist items as requested. Supplemental information from acn 364459: considered calling for new flight plan but it was still open with ATC and we thought we were within 1 hour valid time. Actually the valid time had expired by the time we pushed back again. Should have contacted dispatch for a re-release to cover us. The valid time on the flight plan is actually 10 mins prior to scheduled push time and for 1 hour after that. It took a few mins more than we thought at the last min to get going. We were approximately 20 mins or so over legal time.

Title: ACR MLG RETURNS TO THE RAMP AFTER AN ABORTED TKOF DUE TO NO OIL PRESSURE INDICATION. THE RELEASE TIME FROM DISPATCHER RUNS OUT BUT PIC, UNDER THE IMPRESSION THAT THE RELEASE TIME IS STILL VALID, DEPARTS THE GATE WHEN 20 MINS OVER THE EXPIRATION TIME.

Narrative: ON TKOF ROLL AT APPROX 90-100 KIAS, CAPT TAPPED WITH FINGERS ON OIL PRESSURE GAUGE FOR #2 ENG AND CALLED 'REJECT THE TKOF,' AND PULLED THROTTLES TO IDLE PWR. I INITIATED REVERSE THRUST AND MANUALLY EXTENDED SPD BRAKES AND FELT ONSET OF AUTOMATIC ANTISKID REJECTED TKOF BRAKING. COORD WITH TWR, FLT ATTENDANTS, PAX AND COMPANY OPS WERE COMPLETED IN A TIMELY MANNER AND WE WERE INSPECTED AND RELEASED BY OUR MAINT PERSONNEL. I INQUIRED OF THE CAPT IF WE SHOULD GET A RE-RELEASE FROM OUR DISPATCHERS TO CONTINUE. HE STATED TO ME IT WAS NOT REQUIRED AND TO CONTINUE WITH A CHKLIST PRIOR TO START. WE CONTINUED THE FLT TO DEST UNEVENTFULLY UNDER THE ORIGINAL FLT NUMBER, RELEASE, FLT PLAN, AND A REVISED WT AND BAL. REVIEWING FLT OPS MANUAL DATED DEC/XX/96, THE CAPT AND DISPATCHER MUST AGREE ON THE TERMS OF RELEASE FOR THE FLT. I QUESTIONED THE CAPT FOR A NEW RELEASE BELIEVING OUR DISPATCH TIME HAD ELAPSED AND CONTINUE TO BELIEVE A NEW RELEASE TIME SHOULD HAVE BEEN OBTAINED. SINCE THE ITEM WAS A 'PAPER LEGALITY ITEM' AND NOT AN IMMEDIATE THREAT TO FLT SAFETY, I FOLLOWED THE CAPT'S DIRECTION AND PROCEEDED WITH CHKLIST ITEMS AS REQUESTED. SUPPLEMENTAL INFO FROM ACN 364459: CONSIDERED CALLING FOR NEW FLT PLAN BUT IT WAS STILL OPEN WITH ATC AND WE THOUGHT WE WERE WITHIN 1 HR VALID TIME. ACTUALLY THE VALID TIME HAD EXPIRED BY THE TIME WE PUSHED BACK AGAIN. SHOULD HAVE CONTACTED DISPATCH FOR A RE-RELEASE TO COVER US. THE VALID TIME ON THE FLT PLAN IS ACTUALLY 10 MINS PRIOR TO SCHEDULED PUSH TIME AND FOR 1 HR AFTER THAT. IT TOOK A FEW MINS MORE THAN WE THOUGHT AT THE LAST MIN TO GET GOING. WE WERE APPROX 20 MINS OR SO OVER LEGAL TIME.
