Narrative:

Upon arrival for our originating flight; we found our aircraft had already been deiced. The aircraft and surrounding ramp area were clearly wet with deice fluid; but preflight revealed no obvious fluid leaks. All preflight procedures were followed and we departed the gate without incident. The aircraft was taxied to the runway for departure where takeoff procedures/speeds for fluids applied were again reviewed. Once cleared for takeoff; we taxied into position; held the brakes and advanced power levers to 40% for 10 seconds. All parameters were normal and the takeoff was commenced.shortly after reaching takeoff torque; the #1 and #2 engine oil pressure warning lights simultaneously illuminated. I called 'reject;' assumed control of the aircraft and executed the rejected takeoff procedure. Several seconds later; both warning lights extinguished again at the same time. After clearing the runway; all engine parameters appeared normal. Operations; dispatch; and maintenance were contacted and the flight returned to the gate. An appropriate write-up was then made in the aircraft maintenance log.

Title: A Dash-8 flight crew rejected their takeoff and returned to the gate for maintenance upon receipt of simultaneous low oil pressure warnings on both engines during the takeoff roll.

Narrative: Upon arrival for our originating flight; we found our aircraft had already been deiced.

All preflight procedures were followed and we departed the gate without incident. The aircraft was taxied to the runway for departure where takeoff procedures/speeds for fluids applied were again reviewed. Once cleared for takeoff; we taxied into position; held the brakes and advanced power levers to 40% for 10 seconds. All parameters were normal and the takeoff was commenced.Shortly after reaching takeoff torque; the #1 and #2 engine oil pressure warning lights simultaneously illuminated. I called 'reject;' assumed control of the aircraft and executed the rejected takeoff procedure. Several seconds later; both warning lights extinguished again at the same time. After clearing the runway; all engine parameters appeared normal. Operations; Dispatch; and Maintenance were contacted and the flight returned to the gate.
