Beech B23 accident near Jean, Nevada, June 18, 2011

On June 18, 2011 at about 3:00 pm local time, a Beech B23, registered N6991Q, was substantially damaged in an accident during maneuvering near Jean, Nevada. It was an instructional flight under general aviation rules (Part 91). No one was hurt; 1 person was on board or involved. The weather was visual conditions (good weather).

The NTSB's probable cause their words, unchanged

The student pilot’s improper in-flight fuel management when he did not switch to the fullest fuel tank when the engine began to lose power, which resulted in fuel starvation and the complete loss of engine power during maneuvering flight. Contributing to the accident was the pilot's lack of knowledge of the engine's fuel consumption rate and the inaccurate fuel flow calculations that led to an inaccurate fuel quantity prior to takeoff.

The NTSB's narrative final · quoted from the NTSB record

According to the student pilot, while returning to his home base, he established the airplane in a slow flight configuration. About five minutes later, while he was still performing the slow flight maneuver, the engine began to run rough. The pilot then noticed that the left fuel gauge was indicating less than 1/4 full, and the right tank gauge was indicating over 1/2 full; the engine then lost power. Because he was about 500 feet above the ground when the engine lost power, he did not attempt to restart the engine, nor did he switch the fuel selector to the right tank. The pilot attempted to stretch the glide to the lakebed, but he was unable to do so, and the airplane touched down in an area of soft sand and sagebrush. A postaccident examination of the airplane determined that the left fuel tank was empty, and an undetermined amount of fuel was in the right tank. The pilot miscalculated the fuel burn and relied on his inaccurate fuel gauges to determine the pretakeoff fuel quantity.
