## Sequence of events

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

- Loss of engine power(total) - nonmechanical, approach - vfr pattern - final approach
  - weather condition - carburetor icing conditions (contributing factor)
  - carburetor heat - improper use of, pilot in command (cause)
  - fuel system,carburetor - ice (cause)
- Hard landing, landing - flare/touchdown

## Analysis

THE STUDENT PLT ENTERED THE TRAFFIC PATTERN AFTER MAKING A LOCAL SOLO TRAINING FLT. HE STATED THAT DURING THE LANDING PATTERN, HE REDUCED THE THE THROTTLE INCREMENTALLY & DID NOT USE CARBURETOR HEAT. AS THE ACFT WAS ON FINAL APCH AT ABOUT 50 FT AGL, THE PROPELLER SLOWED DOWN & THE ACFT'S RATE OF DESCENT INCREASED RAPIDLY. SUBSEQUENTLY, THE ACFT TOUCHED DOWN HARD & WAS SUBSTANTIALLY DAMAGED. THE TEMP & DEW POINT WERE 87 & 65 DEG, RESPECTIVELY. ACCORDING TO ICING PROBABILITY CHARTS, SERIOUS CARBURETOR ICING WAS PROBABLE AT GLIDE POWER.
