## Probable cause

ENGINE FAILURE DUE TO CARBURETOR ICE.

## 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 - final approach
  - fuel system,carburetor - ice (cause)
  - anti-ice/deice system,carburetor/heat - not installed (cause)
- Forced landing, descent - emergency
- In flight collision with object, approach - vfr pattern - final approach
  - object - airport facility

## Analysis

THE HOMEBUILT AIRCRAFT COLLIDED WITH A HANGER WHILE ON FINAL APPROACH TO LAND AFTER A LOSS OF POWER. THE TEMP/DEW POINT RATIO WAS 76/55. THIS WAS A DEMONSTRATION FLT WHICH FOLLOWED A SOLO, CHECK OUT FLIGHT AROUND THE PATTERN AND TWO OTHER DEMONSTRATION FLIGHTS. ON-SITE EXAMINATION REVEALED THE PRESENCE OF FUEL AND THAT THE PROPELLER WAS TURNING AT IMPACT. THE DAMAGED PROPELLER AND CARBURETOR WERE REPLACED BECAUSE THE MOUNT FOR THE CARBURETOR WAS BENT, THE GAP AROUND THE CARBURETOR AND FLANG WAS SEALED WITH A SILICONE SEALER AND THE ENGINE RAN SMOOTHLY DURING A TEST RUN.

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.
