## Probable cause

CARBURETOR ICE AND THE PILOT'S IMPROPER USE OF CARBURETOR HEAT.  CARBURETOR ICING CONDITION WAS A RELATED FACTOR.

## 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 - not used, pilot in command (cause)

## Analysis

THE AIRPLANE WAS FLOWN ABOUT TEN MILES FROM THE AIRPORT WHERE THE PILOT CIRCLED HIS SON'S OFFICE AT ABOUT 400 FEET AGL. HE SAID THE ENGINE RPM WAS ABOUT 2300. THE ENGINE LOST POWER & THE PILOT LANDED THE ACFT IN A RESIDENTIAL YARD. DURING THE LANDING, THE ACFT HIT A TREE & CRASHED. THE TEMP & DEW POINT WERE ABOUT 75 & 66 DEG, RESPECTIVELY. ACCORDING TO CARB ICING CHARTS, CONDITIONS WERE CONDUCIVE TO CARB ICE. THE PILOT SAID HE CHECKED THE CARB HEAT DURING RUNUP, BUT DID NOT USE IT IN FLT.
