## Probable cause

PILOT'S FAILURE TO ATTAIN PROPER RUNWAY ALIGNMENT PRIOR TO TOUCHDOWN. A FACTOR IN THE ACCIDENT WAS THE BUILDER'S IMPROPER MODIFICATION OF THE CARBURETORS.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, approach - vfr pattern - base leg/base to final
  - maintenance,modification - improper, pilot in command (contributing factor)
- On ground/water encounter with terrain/water, landing - roll
  - proper alignment - not attained, pilot in command (cause)

## Analysis

A HOMEBUILT AIRPLANE ON ITS INITIAL FLIGHT EXPERIENCED ENGINE STOPPAGE DURING DEPARTURE FROM THE FIELD. THE PRIVATE PILOT STATES HE RESTARTED THE ENGINE AND RETURNED TO HOME FIELD. HE COMMENCED AN APPROACH WITH ANOTHER AIRPLANE ON THE RUNWAY FOR TAKEOFF. HE WAS MAKING A TURN FOR DISPLACEMENT WHEN THE ENGINE QUIT AGAIN. THE OTHER AIRPLANE ROLLED AND THE ACCIDENT PILOT RESUMED HIS APPROACH. THE ACCIDENT AIRPLANE LANDED IN A LEFT BANK, ANGLED OFF THE RUNWAY AND STRUCK A DITCH. EXAMINATION OF THE ENGINE SHOWED THE TWIN CARBURETORS MODIFIED TO A CONFIGURATION AND JETTING NOT APPROVED BY THE ENGINE MANUFACTURER AND FOR WHICH NO TEST OR ENGINEERING DATA WAS AVAILABLE.

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.
