## Probable cause

LOSS OF ENGINE POWER FOR AN UNDETERMINED REASON. THE SOFT TERRAIN WAS A CONTRIBUTING FACTOR.

## Sequence of events

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

- Loss of engine power, takeoff - initial climb
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
- Nose over, landing - roll
  - terrain condition - soft (contributing factor)

## Analysis

THE AG ACFT WAS DEPARTING A PVT STRIP WITH A LOAD OF CHEMICALS. AS IT WAS CLIMBING THRU APRX 100' AGL, THE PLT STARTED TO REDUCE POWER, THEN THE ENG LOST ALL POWER. THE PLT DUMPED THE CHEMICAL LOAD & MADE A FORCED LANDING IN A BEAN FIELD. DURING THE LANDING ROLL, THE WHEELS ENCOUNTERED SOFT TERRAIN & THE ACFT NOSED OVER. AN EXAM OF THE ENG REVEALED ONLY A MINOR CRACK ON THE #5 CYLINDER, NEAR THE FRONT SPARK PLUG HOLE. NO REASON FOR THE RPRTD POWER LOSS COULD BE FOUND.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19890615015769A](https://openairdocs.org/incident/19890615015769A), Jun 15, 1989: Scwzer G164A, Morse, LA, Substantial damage. Engine failed on climbout. Nosed over in a bean field after dumping his load. A engine cylinder had cracked.

## Other investigations on N8916H (2)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
