Factual narrative

AT LIFT-OFF DURING THE DEPARTURE, THE PLT NOTICED OIL SPRAY ON THE WINDSHIELD. HE INITIATED AN ABORTED TAKEOFF BY RETARDING THE THROTTLE, THEN REALIZED THERE WAS INSUFFICIENT RWY REMAINING, SO HE APPLIED FULL THROTTLE AGAIN. HOWEVER, THE ENG DID NOT RESPOND TO THE RAPID THROTTLE ADVANCEMENT. SUBSEQUENTLY, THE ACFT WENT OFF THE RWY NEAR THE DEPARTURE END, HIT A DIRT BANK ADJACENT TO A DITCH & NOSED OVER. ARPT PERSONNEL REPORTED THAT THE PLT HAD SERVICED THE ACFT WITH OIL, BUT HAD FORGOTTEN TO REINSTALL THE OIL FILLER CAP.
