## Sequence of events

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

- Loss of engine power(partial) - mech failure/malf, takeoff - initial climb
  - engine assembly,cylinder - fatigue (cause)
  - engine assembly - cracked (contributing factor)
- Forced landing, landing - flare/touchdown
- Nose over, landing - roll
  - terrain condition - soft (contributing factor)

## Analysis

DURING TAKEOFF, THE ENGINE BEGAN TO VIBRATE AND LOSE POWER. WHILE LANDING IN THE ONLY AVAILABLE AREA, ONE OF THE MAIN GEAR DUG INTO A SOFT SPOT AND THE AIRCRAFT FLIPPED OVER. AN INVESTIGATION REVEALED THAT THE NO. 4 CYLINDER HAD BECOME CRACKED FROM THE FRONT SPARK PLUG HOLE TO THE REAR SPARK PLUG HOLE.
