## Probable cause

The pilot’s inadequate fuel planning which resulted in a loss of engine power due to fuel exhaustion.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

- [Fluids: fuel](https://openairdocs.org/ntsb-findings/01071010): Aircraft › Fluids/misc hardware · Fluid management (probable cause); cases with it: [Aircraft Mfg & Development CH 2000, 2 cases](https://openairdocs.org/ntsb-findings/01071010/cases.md?model=0033001), [All aircraft, 1,695 cases](https://openairdocs.org/ntsb-findings/01071010/cases.md)

## Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event best describes what happened.

- [Enroute-descent: Off-field or emergency landing](https://openairdocs.org/ntsb-events/440); cases with it: [Aircraft Mfg & Development CH 2000, 3 cases](https://openairdocs.org/ntsb-events/440/sequence.md?model=0033001), [All aircraft, 3,365 cases](https://openairdocs.org/ntsb-events/440/sequence.md)
- [Enroute-descent: Fuel exhaustion](https://openairdocs.org/ntsb-events/192) (defining event); cases with it: [Aircraft Mfg & Development CH 2000, 2 cases](https://openairdocs.org/ntsb-events/192/sequence.md?model=0033001), [All aircraft, 804 cases](https://openairdocs.org/ntsb-events/192/sequence.md)

## Analysis

The pilot reported that, he departed with 28 gallons of fuel onboard for a cross-country flight and he used 100% power during the flight. The flight was uneventful for a little over four hours, until the pilot was approaching his destination and the engine began to run rough and sputter. The pilot was unable to reach a nearby airport and force-landed the airplane in an open field where the nose landing gear collapsed, which resulted in substantial damage to the lower fuselage. The pilot and a law enforcement examined the fuel tank and discovered that the fuel tank was empty. Fuel usage computations indicated the engine likely consumed all the fuel onboard while operating at 100% power. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
