Amateur-built CH601XLB N274AJ accident near Alpine, Texas

Probable cause

The pilot/builder's failure to properly adjust the fuel flow, which resulted in reduced flow to the engine and a subsequent total loss of engine power.

NTSB analysis

The pilot/builder, an airframe and powerplant mechanic, stated that the engine had been experiencing low oil pressure and that he performed work on the oil system the day before the accident. On the day of the accident, he taxied the airplane for about 20 minutes and did not observe any anomalies. He then departed on a postmaintenance test flight. A few minutes after takeoff, the engine sputtered and experienced a total loss of power. The pilot selected a small open area in which to land. During the forced landing approach, the pilot saw wires across the flight path and attempted to fly under them. The airplane contacted the lowest wire and the airplane nosed down into a carport alongside a residence.

The pilot reported that he examined the engine after the accident. He stated that he failed to adjust the fuel flow after installing a high-pressure fuel pump, which resulted in insufficient fuel flow to the engine.
