## Probable cause

The loss of engine power due the failure of a connecting rod.  A contributing factor was the lack of suitable terrain for the forced landing.

## 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, maneuvering
  - engine assembly,connecting rod - failure (contributing factor)
- Forced landing, emergency descent/landing
- On ground/water collision with object, emergency landing
  - terrain condition - none suitable (contributing factor)
  - object - fence

## Analysis

The 10,300-hour commercial pilot was conducting an aerial application flight.  During the flight the airplane's engine experienced a drop in RPM.  The pilot elected to return to the airport.  While en route, the engine experienced a drop in manifold pressure and a emitted a large puff of smoke from the engine.  The engine subsequently experienced a total loss of power and the pilot executed an emergency landing to a pasture.  Upon roll out the airplane struck a barbwire fence and came to rest in an upright position.  Examination of the engine revealed a hole on the top of the engine case, consistent with a connecting rod failure.  The engine was found to have accumulated a total time of 766 hours, with 122 hours since its last inspection.
