HISTORY OF FLIGHT On December 9, 2005, at 2240 eastern standard time, an Embraer EMB-110P1, N790RA, registered to and operated by Business Air Incorporated, doing business as Air Now, operating as a 14 CFR Part 91 positioning flight, lost power in both engines, and collided with trees during a forced landing a quarter-mile away from Orangeburg Municipal Airport, Orangeburg, South Carolina. Visual meteorological conditions prevailed and an instrument flight rules flight plan was filed. The airplane received substantial damage. The commercial-rated pilot reported serious injuries. The flight departed Savannah International Airport, Savannah, Georgia, en route to Columbia, South Carolina, on December 9, 2005, at 2100. The pilot stated she had flown the airplane the day before the accident and after she landed at the Savannah International Airport, on the morning of the accident, she ordered fuel for the airplane. While exiting the airplane another pilot informed her that he had heard a "popping noise" coming from one of the engines. The pilot of the accident airplane elected to start the airplane and taxied to a run up area to conduct an engine run up. The fuel truck arrived at the run up area and the pilot elected not to refuel the airplane at that time and continued the run up. No anomalies were noted during the run up and the airplane was taxied back to the ramp and parked. The pilot arrived back at the airport later that day. She did not re-order fuel for the airplane nor did she recall checking the fuel tanks during the preflight inspection of the airplane. The pilot stated she departed Savannah and was in cruise flight when she noticed the fuel light on the annunciator panel flickering. The pilot checked the fuel gauges and observed less than 100 pounds of fuel per-side indicated. The pilot declared low fuel with Columbia Approach Control personnel, and requested to divert to the nearest airport, Orangeburg Municipal. The air traffic controller cleared the pilot for a visual approach to the airport. The pilot keyed the microphone to turn the runway lights on and lowered the landing gear. The left engine quit followed by the right engine. The pilot made a forced landing into the trees about 1/4 mile from the approach end of runway 36. The pilot exited the airplane and telephoned 911 emergency operators on her cell phone. The pilot stated she did not experience any mechanical problems with the airplane before the accident.
