Flight Crew Rejected Takeoff; General Maintenance Action
Aircraft
We were cleared for takeoff and I advanced levers and commenced takeoff roll. The auto feather armed and the engines continued to increase power. Upon reaching about 70-80% torque; the number one engine low oil PSI master warning light flashed about 3 times. I retarded the power levers; aborted the takeoff and we notified ATC. The low oil pressure light went out and oil PSI remained above 55 PSI. I called for the rejected takeoff checklist. We finished all appropriate checklists; advised passengers; and called maintenance to advise them. We both agreed to taxi back to the gate. We advised ground of our decision and taxied back to gate.
Dash 8-300 Captain reported rejecting the takeoff when he noticed Number 1 engine low oil pressure warning light had flashed several times.
