## Probable cause

The non-certificated pilot’s failure to configure the airplane for takeoff, which resulted in a runway excursion.

## Findings

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

- [Propeller system: propeller governor](https://openairdocs.org/ntsb-findings/01046122): Aircraft › Aircraft propeller/rotor · Incorrect use/operation (probable cause); cases with it: [All aircraft, 16 cases](https://openairdocs.org/ntsb-findings/01046122/cases.md)
- [Experience/qualifications: qualification/certification](https://openairdocs.org/ntsb-findings/02031010): Personnel issues › Experience/knowledge · Other (probable cause); cases with it: [All aircraft, 280 cases](https://openairdocs.org/ntsb-findings/02031010/cases.md)

## Sequence of events

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

- [Takeoff: Runway excursion](https://openairdocs.org/ntsb-events/300) (defining event); cases with it: [All aircraft, 3,643 cases](https://openairdocs.org/ntsb-events/300/sequence.md)

## Analysis

The non-certificated pilot reported that he forgot to adjust the airplane’s propeller control before takeoff from his private airstrip. During takeoff, the airplane overran the runway and impacted parked machinery on his personal property. The airplane sustained substantial damage to its fuselage. The pilot did not make the airplane available for examination and did not cooperate with local and federal investigators; therefore, further information could not be obtained.

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.
