## Sequence of events

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

- Loss of engine power, descent - normal
  - weather condition - carburetor icing conditions (cause)
  - in-flight planning/decision - inadequate, pilot in command (cause)
  - carburetor heat - not selected, pilot in command (cause)
- Forced landing, descent - normal
- In flight collision with object, landing - flare/touchdown

## Analysis

THE PILOT DESCENDED THE AIRPLANE FROM 5000 FEET USING REDUCED POWER BUT WITHOUT USING CARBURETOR HEAT.  AT 3500 FEET THE PILOT ADVANCED THE THROTTLE BUT THE ENGINE DID NOT ACCELERATE AND THEN STOPPED PRODUCING POWER COMPLETELY. DESPITE CORRECTIVE MEASURES BY THE PILOT, THE ENGINE WOULD NOT RUN. DURING THE FORCED LANDING, THE LEFT WING HIT A TREE. NO FUEL WAS FOUND IN THE FUEL SYSTEM BUT THE CARBURETOR WAS BROKEN OPEN DURING GROUND IMPACT.  THE PILOT STATED HE SAW THE FUEL QUANTITY GAUGE AND FUEL PRESSURE GAUGE INDICATING PROPERLY BEFORE THE TREE IMPACT.  THE ICING PROBABILITY CHART INDICATES THE TEMPERATURE/DEW POINT WAS RIGHT FOR SERIOUS CARBURETOR ICING AT GLIDE POWER.

## Other investigations on N5932P (1)

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.
