## 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, descent - normal
  - lubricating system,oil filter/screen - worn (cause)
  - lubricating system,oil filter/screen - leak (cause)
- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ditch (contributing factor)
- Nose gear collapsed, landing - roll
  - landing gear,nose gear - overload
  - landing gear,nose gear - separation

## Analysis

A LOSS OF POWER OCCURRED DURING DESCENT FOR LANDING. DURING FORCED LANDING THE AIRCRAFT STRUCK AN IRRIGATION DITCH, COLLAPSING THE NOSE GEAR. THE REASON FOR THE ENGINE FAILURE WAS A COMPLETE LOSS OF OIL COMING FROM WORN THREADS AND A WORN O RING TO THE OIL FILTER ADAPTER.
