## Sequence of events

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

- Loss of engine power, cruise
  - carburetor heat control - jammed (cause)
  - carburetor heat control - inoperative (cause)
  - weather condition - carburetor icing conditions (contributing factor)
  - fuel system,carburetor - ice (cause)
- Nose gear collapsed, landing - roll
  - terrain condition - rough/uneven (contributing factor)

## Analysis

DURING CRUISE THE PILOT NOTICED A GRADUAL LOSS OF RPM. CARBURETOR HEAT WAS APPLIED BUT THE PILOT STATED THAT HE NOTED NO IMPROVEMENT IN THE ENGINE POWER. THE POWER LOSS CONTINUED TO DETERIORATE SO A LANDING WAS MADE ONTO A ROUGH FIELD WHERE THE NOSE GEAR COLLAPSED DURING THE LANDING ROLL. EXAMINATION OF THE AIRCRAFT AND ENGINE BY A MECHANIC REVEALED THE CARBURETOR HEAT CONTROL JAMMED IN THE COLD POSITION.
