## Probable cause

THE PILOT'S FAILURE TO MAINTAIN AIRSPEED WHICH RESULTED IN AN INADVERTENT STALL AND UNCONTROLLED DESCENT TO THE GROUND. FACTOR RELATED TO THE ACCIDENT WERE THE PILOT'S LACK OF EXPEREINCE IN THE TYPE OF AIRPLANE AND THE PARTIAL LOSS OF ENGINE POWER.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of engine power, approach - vfr pattern - final approach
  - reason for occurrence undetermined (contributing factor)
- Loss of control - in flight, approach - vfr pattern - final approach
  - lack of familiarity with aircraft, pilot in command (contributing factor)
  - airspeed - not maintained, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - grass

## Analysis

WORK WAS ACCOMPLISHED ON THE ENGINE OF THE HOMEBUILT AIRPLANE PRIOR TO DEPARTURE.  THE AIRPLANE WAS OBSERVED TO RETURN TO THE AIRPORT AFTER A FEW MINUTES, IN A SHALLOW DESCENT AND FLYING VERY SLOW, 'POSSIBLY NEAR STALL SPEED.'  WITNESSES REPORTED THE ENGINE WAS RUNNING BUT DID NOT APPEAR TO BE DEVELOPING FULL POWER.  AS THE AIRPLANE CROSSED THE AIRPORT BOUNDARY, WITNESSES REPORTED IT APPEARED TO PULL UP, STALL, AND DESCEND TO THE GROUND.  THE AIRPLANE STRUCK THE GROUND ON THE RIGHT WING, CARTWHEELED, AND LANDED UPSIDE DOWN.  THE PILOT CRAWLED OUT OF THE BURNING WRECKAGE. DUE TO IMPACT AND POST CRASH FIRE, THE CAUSE OF THE PARTIAL POWER LOSS WAS NOT DETERMINED.

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.
