## Sequence of events

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

- Loss of engine power(total) - mech failure/malf, climb - to cruise
  - fluid,oil - improper (cause)
  - aircraft preflight - inadequate, pilot in command (cause)
  - weather condition - temperature extremes (contributing factor)
- Forced landing, landing - flare/touchdown
- Hard landing, landing - flare/touchdown
  - level off - improper, pilot in command (cause)
- Gear collapsed, landing - flare/touchdown
  - landing gear - overload

## Analysis

THE TEMPERATURE WAS APPROXIMATELY A MINUS 15 DEGREES FAHRENHEIT. THE PILOT REPORTED THE ENGINE WAS PREHEATED FOR 30 MINUTES AND THAT EVERYTHING WAS IN THE GREEN BEFORE TAKEOFF. SHORTLY AFTER TAKEOFF, THE ENGINE BEGAN TO OVERSPEED. THE PILOT THROTTLED BACK AND TURNED BACK TOWARD THE AIRPORT; HOWEVER, THE ENGINE SEIZED. DURING A FORCED LANDING, THE AIRCRAFT STALLED ABOUT 25 FT ABOVE THE RUNWAY DAMAGING THE GEAR AND THE WINGS. EXAMINATION OF THE ENGINE REVEALED A CRACKED CRANKCASE, BUT NO OTHER MECHANICAL FAILURES. THE ENGINE HAD AN ADEQUATE SUPPLY OF OIL, BUT THE VISCOSITY WAS ANALYZED AND FOUND TO BE ABOUT SAE 55. THE STANDARD WINTER PROCEDURE REQUIRED A LOWER VISCOSITY AND/OR AN ADEQUATE ENGINE WARM UP AFTER ENGINE START.
