## Sequence of events

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

- Loss of engine power(total) - nonmechanical, cruise - normal
  - fuel system,carburetor - ice (cause)
  - carburetor heat - improper use of, pilot in command (cause)
  - in-flight planning/decision - improper, pilot in command (contributing factor)
- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, landing - roll
  - proper touchdown point - misjudged, pilot in command (contributing factor)
  - terrain condition - rough/uneven (contributing factor)

## Analysis

DURING A PLEASURE FLIGHT, THE PILOT REDUCED THE ENGINE POWER TO TALK TO THE PASSENGER. WHEN THE PILOT APPLIED POWER, THE ENGINE DID NOT RESPOND. THE AIRPLANE WAS GLIDED TO A NEARBY AIRPORT; HOWEVER, THE AIRPLANE LANDED SHORT. THE PILOT VERBALLY REPORTED THERE WERE NO MECHANICAL FAILURES OR MALFUNCTIONS. THE CONDITIONS WERE CONDUCIVE FOR CARBURETOR ICE DURING ENGINE IDLE OPERATIONS.

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.
