Aviation Accident Summary CEN21LA302

Wichita, KS, USA

Aircraft #1

N10HK

PIPER AEROSTAR 600A

Analysis

The pilot was conducting a cross-country flight in the multiengine airplane when, about 8 miles north of the intended destination, the right engine began “sputtering and popping,” and he shut it down and feathered the propeller. Shortly thereafter, the left engine began “slowly spooling down” and the airplane was not able to maintain airspeed and altitude. The pilot performed a forced landing to a flat, muddy wheat field, resulting in substantial damage. A postaccident examination of the airplane revealed no anomalies. There was no evidence of fuel at the accident site or in the airplane. During the recovery of the airplane from the field, no fuel was found in the three intact fuel tanks nor in any of the engine fuel lines. The pilot later stated that he ran the airplane out of fuel.

Factual Information

On July 1, 2021, about 1908 central daylight time, a Piper Aerostar 600A, N10HK, was substantially damaged when it was involved in an accident near Wichita, Kansas. The commercial pilot sustained serious injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot was conducting a cross-country flight when, about 8 miles north of his intended destination, he reduced engine power, pitched for level flight, and waited for indicated airspeed to drop below 174 kts to add 20° of flaps. As soon as the drag was introduced, the airplane began to “buck back and forward,” and the two engines were “throttling up and down on their own.” He noted that the right engine seemed to be “sputtering and popping” more than the left engine, so he decided to raise the flaps and to shut down and feather the right engine. He declared an emergency to air traffic control. The pilot then noticed that the left engine was “slowly spooling down” and the airplane was not able to maintain airspeed and altitude. The pilot performed a forced landing to a flat, muddy wheat field about 4 nautical miles from the airport. The airplane sustained substantial damage to the fuselage and to both wings. A Federal Aviation Administration inspector traveled to the accident site to examine the airplane. Flight control and engine control continuity were confirmed. The master switch was turned on and the fuel gauges showed a zero indication. There was no evidence of fuel at the accident site or in the airplane. During the recovery of the airplane from the field, no fuel was found in the three intact fuel tanks, nor in any of the engine fuel lines. The pilot later stated that he ran the airplane out of fuel during the accident flight. The pilot reported that, during the preflight checks and twice during the accident flight, he activated the low fuel warning light, and no anomalies were noted. Postaccident testing of the low fuel warning light in an exemplar Piper Aerostar 602P revealed no anomalies.

Probable Cause and Findings

The pilot’s improper fuel planning and management, which resulted in a total loss of engine power due to fuel exhaustion.
