On March 14, 2014, about 1730 eastern daylight time, a Cessna 402B, N419AR, was substantially damaged when it collided with terrain while making a forced landing following loss of power in both engines while on short final approach to Witham Field Airport, Stuart, Florida. The commercial pilot sustained minor injuries. The airplane was registered to and operated by the commercial pilot under the provisions of 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed and no flight plan was filed for the personal flight. The flight departed from St. Lucie County International Airport (FPR), Fort Pierce Florida at 1705. According to the pilot, prior to departing he checked the fuel gauges and determined that he had approximately 28 gallons of fuel onboard, which he calculated as 1 hour of flight time. He did not indicate that he visually checked the fuel level in the tanks before departure. As he approached his destination airport he was instructed by air traffic control (ATC) to enter a 2 mile left base. Approximately 3 miles from the airport, ATC advised him to intercept a 6 mile final. The pilot stated that, at the time, he wasn't aware he had a fuel shortage situation. After turning final, the pilot configured the airplane for landing, and approximately one and a half miles from the runway, the left engine "quit." The pilot elected not to feather the left propeller because it would take six seconds to complete. Instead, he turned the left fuel valve to the left inboard fuel tank and the left engine restarted successfully; however, the right engine then "quit." The pilot then attempted to turn the right fuel valve to the right inboard tank, but the left engine quit again. The pilot made a forced landing in a field and impacted a tree before colliding with the ground, which resulted in substantial damage to both wings and the fuselage. The pilot stated that, upon exiting the airplane, he saw that a section of the right wing was inverted and "fuel was coming out of the right vent." The Federal Aviation Administration (FAA) inspector who responded to the scene about 3.5 hours after the accident reported that he did not detect any fuel odor at the scene and that examination of the airplane revealed no evidence of fuel leakage. The FAA inspector stated that a law enforcement officer on scene informed him that the fire department personnel who responded to the scene did not spray any foam on the airplane because there was no fuel leaking from it. Examination of the engines by the FAA revealed that due to external damage, an engine run could not be performed on either engine. An examination of the engines revealed that both engines were rotated by hand and valve train continuity and cylinder compression was obtained. Further examination revealed that spark was obtained on all ignition leads. Examination of the aircraft systems did not revealed any anomalies that would have precluded normal operation. Examination of the left wing tanks revealed that they were void of fuel. The right wing was separated from the fuselage and, although they were breached, no evidence of fuel was noted in any of the right wing tank. In the pilot's written statement submitted to the NTSB, he indicated that the airplane was topped off with fuel the night before the accident. His statement described that, on the day of the accident, he flew several short flights before the accident flight. He provided his fuel endurance calculation for the airplane with full fuel then subtracted the "flight time" for each of the previous flights from that total endurance time to determine that, before departing on the accident flight, the airplane should have had "2 hours 23 minutes fuel left, without takeoff and landing." The pilot explained the approaches for each of these flights and indicated that he taxied to the ramp to pick up and drop off friends at each destination.
