## Probable cause

CARBURETOR ICE, DUE TO THE PILOT'S IMPROPER USE OF CARBURETOR HEAT.  FACTORS RELATED TO THE ACCIDENT WERE: CARBURETOR ICING (WEATHER) CONDITIONS, AND OBSTRUCTIONS (HOUSES AND UTILITY POLE) IN THE EMERGENCY LANDING AREA.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, maneuvering
  - weather condition - carburetor icing conditions (contributing factor)
  - fuel system,carburetor - ice (cause)
  - carburetor heat - improper use of, pilot in command (cause)
- Forced landing, descent - emergency
- In flight collision with object, landing
  - object - residence (contributing factor)
  - object - utility pole (contributing factor)

## Analysis

THE PILOT TOOK OFF, FLEW TO ANOTHER AIRPORT, AND MADE A LANDING.  AFTER LANDING, HE TAXIED BACK TO THE RUNWAY FOR THE RETURN FLIGHT.  AFTER TAKEOFF, HE CLIMBED ABOUT 500 TO 750 FEET AND BEGAN A TURN TO DOWNWIND, THEN NOTICED THE AIRPLANE WOULD NOT CLIMB DESPITE FULL THROTTLE.  HE TRIED TO LAND BACK ON THE AIRPORT.  HE SAID HE 'RECHECKED THE THROTTLE, FUEL SHUTOFF VALVE ON, IGNITION SWITCH BOTH, CARBURETOR HEAT, OFF, MIXTURE, IN.'  SUBSEQUENTLY, THE AIRPLANE DESCENDED, STRUCK THE TOPS OF 2 HOUSES AND A UTILITY POLE, THEN CAME TO REST IN THE FRONT YARD OF A RESIDENCE.  NO PREIMPACT PART FAILURE WAS FOUND, AND FUEL WAS DRAINED FROM THE CARBURETOR.  THE TEMPERATURE AND DEW POINT WERE 76 & 60 DEGREES, RESPECTIVELY.  ACCORDING TO ICING PROBABILITY CURVES, CONDITIONS WERE CONDUCIVE FOR CARBURETOR ICE.
