Probable cause

The pilot's improper in-flight decision making and inadequate fuel consumption calculations that resulted in fuel exhaustion.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot took off with 38 gallons of fuel on board, and planned a 3-hour flight to his refueling stop. After departure he followed the wrong highway northeast. He realized his mistake, adjusted his course to intercept the correct highway, and continued on to his destination. He flew at 4,500 feet mean sea level (msl) and 110 miles per hour (mph) ground speed according to his global positioning system (GPS). Winds aloft at 4,950 feet msl were from 320 degrees at 21 knots, providing a strong headwind. After 4.4 hours of flight, the airplane ran out of fuel near his refueling stop, and the pilot made a forced landing into a vineyard near the airport.

Factual narrative

In a written statement, the pilot reported that he took off with 38 gallons of fuel on board. The flight northwest from Van Nuys, California, to Rohnerville, California, should have taken 3 hours 30 minutes. After departure the pilot believed he was following highway I-5, but became confused when he did not recognize landmarks. He realized he had followed highway 14 through Palmdale, California. When the airplane was north of Palmdale, he corrected his course toward I-5 and his destination. He descended from 8,500 feet mean sea level (msl) to 2,500 feet msl in an attempt to find smooth air and fastest ground speed. He climbed to 4,500 feet msl and flew at 110 miles per hour (mph) ground speed according to his global positioning system (GPS). He did not keep track of the elapsed time from takeoff because he had made the trip to his refueling stop, Santa Rosa, California, in 3 hours before. He began a descent into Santa Rosa, and at 800 feet above ground level (agl), the engine rpm (revolutions per minute) dropped abruptly and the pilot realized the airplane had run out of fuel. He made a forced landing into a vineyard near the airport. At the time of the accident, the Hobbs meter showed an elapsed flight time of 4.4 hours. The pilot indicated that the airplane and engine had no mechanical failures or malfunctions during the flight.

At 1700 Pacific daylight time, winds aloft at Oakland International Airport were reported from 290 degrees at 14 knots at 2,585 feet msl. At 4,950 feet msl, winds were reported from 320 degrees at 21 knots. At 6,351 feet msl, winds were reported from 324 degrees at 22 knots.
