History of flight

On October 9, 2001, at 1322 central daylight time, a Beech C90 (King Air) twin-turboprop airplane, N690JP, was substantially damaged when it impacted a residential area during a forced landing following a loss of engine power while on approach to the Dallas Love Airport, Dallas, Texas. The airplane was registered to J & D Aircraft Sales LLC of Pasco, Washington. The airplane was operated by private individuals, who were in the process of purchasing the aircraft. The commercial pilot, who was the sole occupant, sustained serious injuries. Visual meteorological conditions prevailed and an instrument flight rules flight plan was filed for the 14 Code of Federal Regulations Part 91 business flight. The cross-country flight originated from Taos, New Mexico, at 1115 (2 hours and 7 minutes prior to the accident).

According to reports from Dallas Love Air Traffic Control Tower, the flight was on a visual approach to runway 13L. When the airplane was on final approach, the controller noticed the airplane in "level flight descending out of sight behind hangars." The controller asked the pilot if he was experiencing a problem; however, the controller did not receive a reply. The airplane descended into a residential area where it struck power lines, a tree, a natural gas meter, two private residences, and a fence.

According to an FAA inspector, who responded to the accident site, the flight departed from Dallas Love Airport at 0757 on the morning of the accident after the pilot had the fuel tanks topped off with 244 gallons of fuel. Air traffic control data indicated that the airplane descended from radar coverage into Taos at 1044 (2 hours and 47 minutes after departure). According to service personnel in Taos, the airplane was on the ground for approximately 15 minutes, and departed for Dallas with just the pilot on board.

An FAA inspector, who interviewed the pilot on October 10, 2001, stated that the pilot reported that while the airplane was on base leg to runway 13L at Dallas Love, the right engine began to surge. The pilot turned on the boost pumps and retracted the landing gear. The pilot reported that the right engine lost total power and the airplane's airspeed was approaching the minimum controllable airspeed (Vmc); therefore, he reduced power on the left engine and attempted a forced landing to the residential area.

In a written statement, submitted to the NTSB investigator-in-charge (IIC) on January 4, 2002, the pilot reported that the return flight from Taos was uneventful until the flight approached Wichita Falls, Texas, when the pilot noticed that the right hand fuel gauge "spiked to zero and returned to its previous indication." The pilot reported that the "anomaly happened twice and did not occur again for the remainder of the flight." He added that the flight continued "normally" until the airplane turned onto short final for runway 13L. The right engine "began to surge violently, so [he] brought the power back and increased power to the left engine. This made the airplane aircraft roll to the right, so [he] brought [the left] engine back as well." The pilot realized that the airplane would not make it to the runway and he looked for a place to land. The pilot found an alley in a residential area and attempted to land there. He stated that the airplane was about to impact the power lines, so he "retracted the landing gear, brought the condition levers back to cut-off, and kept flying until [he] blacked out."

One witness, who was located in the residential area, stated that she heard a "crackling sound," which caused her to look up and see the airplane "barely hitting the electric tower. The motor wasn't on." She added that one of the wings clipped a television satellite dish and the side of a house. The aircraft continued across the street and impacted a garage and a tree where it came to rest.

Another witness, who was also located in the residential area, stated that he noticed the airplane flying very low. He observed the airplane impact electrical wires with the lower left wing and "sparks flew everywhere." The airplane then disappeared from his view. He added that he thought the "engines were missing or sputtering."

Personnel information

The commercial pilot held a second class medical certificate without limitations that was issued on May 25, 2001. The pilot reported having accumulated approximately 7,000 total flight hours, of which 5,000 hours were in multi-engine airplanes and 100 hours were in the same make and model as the accident airplane.

Aircraft information

The aircraft was equipped with two 550 shaft-horsepower Pratt & Whitney PT6A-21 engines. Review of maintenance records revealed that the aircraft underwent Phase 2 and Phase 3 inspections in accordance with the Beech King Air inspection procedures on April 27, 2001, at an aircraft total time of 7,325.2 hours. At the time of the last inspection, the engines had accumulated a total of 7,325.2 hours, and had accumulated 3,892.2 and 3,669.8 hours since the last overhaul on the left and right engines, respectively. The left and right engines had accumulated 1,405.2 and 1,182.8 hours since their last hot section inspections, respectively. During the aircraft's last inspection, McCauley 4-bladed propellers were installed in accordance with Supplemental Type Certificate (STC) SA1241GL at propeller total times of 50.8 hours for both the left and right propellers. At the time of the accident, the airplane had accumulated a total of 7,356 hours.

According to the King Air C90 Pilot Operating Handbook fuel system description, "the fuel system consists of two separate systems connected by a crossfeed system. Fuel for each engine is supplied from a nacelle tank and four interconnected wing tanks for a total of 192 gallons of usable fuel for each side with all tanks full. The outboard wing tanks supply the center section wing tank by gravity flow. The nacelle tank draws its fuel supply from the center section tank. Since the center section tank is lower than the other wing tanks and the nacelle tank, the fuel is transferred to the nacelle tank by the fuel transfer pump in the low spot of the center section tank. Each system has two filler openings, one in the nacelle tank and one in the leading edge tank. To assure that the system is properly filled, service the nacelle tank first, then the wing tanks."

In written statements provided by the fueling service in Dallas, the aircraft refueling personnel, who fueled the airplane on the morning of the accident, stated that they filled the nacelle fuel tanks prior to filling the wing fuel tanks.

Wreckage and impact information

The airplane came to rest upright in the yard of a residence. A tree was crushed under the belly of the aircraft. Review of photographs taken at the accident site revealed that the airplane's wings, outboard of both engines, sustained impact damage, which compromised the fuel system. The propellers remained attached to the engines. The left and right propeller blades were intact and attached to the propeller hubs and were bent and twisted. The engines remained attached to their wings; however, they were deflected downward. The left horizontal stabilizer was torn from its attachment fitting.

FAA inspectors arrived at the accident site at 1415, and documented the cockpit. Cockpit documentation revealed that the fuel boost and transfer pumps were in the OFF position, the power levers were in the mid-range position, the propeller levers were in the full forward position, and the condition levers were at the low idle position. The rudder trim was set in the neutral position, the aileron trim was found in the maximum (5 degrees) right wing down trim, and the elevator trim was set at a 7 degree up position.

The aircraft was transported to Air Salvage of Dallas, Lancaster, Texas, for furthe
