## Probable cause

The pilot's failure to maintain adequate airspeed, which resulted in a stall.

## Findings

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

- [Performance/control parameters: airspeed](https://openairdocs.org/ntsb-findings/01062010): Aircraft › Aircraft oper/perf/capability · Not attained/maintained (probable cause); cases with it: [All aircraft, 1,681 cases](https://openairdocs.org/ntsb-findings/01062010/cases.md)

## Sequence of events

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

- [Initial climb: Loss of control in flight](https://openairdocs.org/ntsb-events/240) (defining event); cases with it: [All aircraft, 5,002 cases](https://openairdocs.org/ntsb-events/240/sequence.md)

## Analysis

The non certificated pilot took off from a private airstrip and performed several touch-and-go landings. He then landed, picked up a passenger, and took off again. After the airplane climbed about 40 feet, it turned slightly, stalled, and descended rapidly before colliding with terrain.

## Factual narrative

According to a Federal Aviation Administration (FAA) inspector, the unregistered airplane did not meet the requirements for an ultralite airplane, and did not have a waiver. The pilot did not hold an FAA pilot certificate. The pilot took off from a private airstrip and performed several touch-and-go landings. He then landed, picked up a passenger, and took off. After the airplane climbed about 40 feet, it turned slightly, stalled, and descended rapidly before colliding with terrain.
