Aviation Accident Summary LAX96LA198

LOS ANGELES, CA, USA

Aircraft #1

N58KD

Beech 58

Analysis

The pilot reported that in preparation for the flight he added 60 gallons of fuel to his airplane. He performed a preflight inspection which included draining the fuel sumps and no evidence of contaminants. Both engines started normally and no discrepancies were observed during the pre-takeoff engine and propeller checks. The pilot reported that during takeoff, the airplane lifted off the runway at the same approximate location. A positive rate of climb was established, and the landing gear was retracted. The right engine suddenly lost all power and the fuel flow indicator read 0 gallons per hour. The pilot turned on the fuel boost pump, but the engine did not restart and the propeller was feathered. Afterwards, the pilot unfeathered the right engine's propeller, pushed the right throttle forward, and again turned the boost pump on. None of these actions restored the engine's power and the airplane would not maintain altitude. Unable to return to the airport, the pilot made a forced landing on the rough terrain of a nearby golf course. The FAA examined the airplane and associated maintenance records. No discrepancies were found with the fuel pump, fuel metering unit, manifold valve, and the injector lines and nozzles.

Factual Information

HISTORY OF FLIGHT On May 18, 1996, at 1144 hours Pacific daylight time, a Beech 58, N58KD, owned and operated by the pilot, experienced a loss of right engine power during takeoff from the Whiteman Airport, Los Angeles, California. The airplane collided with terrain near the airport and was substantially damaged. Neither the private pilot nor the two passengers were injured. Visual meteorological conditions prevailed at the time of the personal flight which was originating at the time of the accident. The local air traffic controller reported that seconds after the airplane became airborne from runway 12, the pilot reported he was losing power in his right engine. The controller cleared the pilot to land using any runway. The controller stated that he did not hear an acknowledgment from the pilot, but he did observe the airplane in a descending right turn. The pilot made a forced landing in rough terrain near the 15th hole of the Hanson Dam golf course. In the pilot's completed accident report, he indicated that in preparation for his personal flight to Santa Ynez with his wife and daughter, he had arrived at the Whiteman Airport around 1100. Sixty gallons of fuel were added (30 gallons per wing tank) to the hangared airplane, and the three fuel sumps were drained with no evidence of contaminants. The pilot further reported that both engines started normally, and no discrepancies were observed during the pre-takeoff engine and propeller checks. The pilot reported that during takeoff the airplane "lifted off the runway at the same approximate location we normally do," a positive rate of climb was established, and the landing gear was retracted. Suddenly and without warning, the right engine lost all power, and the right engine's fuel flow indicator read 0 gallons per hour. The pilot turned on the fuel boost pump for the right engine, but the engine did not restart. The pilot said he then feathered the right engine's propeller, made a slight left turn toward the golf course, and tried to maintain altitude. The pilot further reported that he then unfeathered the right engine's propeller, pushed the right throttle forward and turned the boost pump on (again). None of these actions restored the engine's power, and the airplane did not maintain altitude. TESTS AND RESEARCH Federal Aviation Administration (FAA) airworthiness inspectors reviewed the airplane's maintenance records and examined the airframe and engine. The FAA found no evidence of fuel contamination, and reported that the "aircraft tear down revealed no abnormal conditions or findings." The following right engine components were removed and examined under FAA supervision: the fuel pump and drive coupling; the throttle/fuel control metering unit; the manifold valve; and the injector lines and nozzles. Following the examinations, the FAA reported that no discrepancies were found with any of these components.

Probable Cause and Findings

an interruption of fuel flow to the right engine for undetermined nonmechanical reasons. A contributing factor was the pilot's failure to keep the right engine's propeller feathered which reduced the airplane single engine performance capabilities.
