## Probable cause

THE IMPROPER INSTALLATION/MAINTENANCE OF THE CARBURETOR HEAT CONTROL. A FACTOR WAS THE PILOT'S RESTRICTED VISUAL OUTLOOK.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, takeoff - initial climb
  - carburetor heat control - inoperative
  - maintenance,installation - improper, other maintenance personnel (cause)
  - weather condition - carburetor icing conditions
  - carburetor heat - unavailable
- Forced landing, descent - emergency
- On ground/water collision with object, landing - roll
  - object - fence post
  - visual lookout - restricted, pilot in command (contributing factor)

## Analysis

THE PILOT STATED THERE WAS A LOSS OF ENGINE POWER AS THE HOMEBUILT AIRPLANE REACHED ABOUT 500 FEET ABOVE THE GROUND DURING INITIAL CLIMB. HE PERFORMED A FORCED LANDING WITH THE RETRACTABLE NOSE GEAR UP AND LOCKED.  THE AIRPLANE STRUCK A FENCE POST THAT WAS OBSCURED BY THE NOSE OF THE AIRPLANE DURING THE APPROACH AND LANDING FLARE.  THE ENGINE OPERATED NORMALLY DURING A POSTACCIDENT RUN UP. INVESTIGATION REVEALED THE CARBURETOR HEAT HOSE WAS DISCONNECTED. WEATHER CONDITIONS WERE CONDUCIVE TO THE FORMATION OF CARBURETOR ICE.
