## Probable cause

The loss of engine power for undetermined reasons.

## Sequence of events

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

- Loss of engine power, maneuvering - aerial application
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, emergency descent/landing
  - terrain condition - ground

## Analysis

The agricultural spray airplane sustained substantial damage during a forced landing to a field after a loss of engine power.  The pilot reported that the airplane was operating normally after he had departed the airport and had flown about 10 miles to the field he was preparing to spray.  He reported that during the first swath the engine "started to shake badly and power started to decay."  The engine RPM's continued to decay so he executed a forced landing to a field, and the airplane sustained substantial damage from the rough terrain.  The cause of the reported loss of engine power was not determined.

## Flight crew

As NTSB recorded them. NTSB leaves out names.

- Pilot; age 59; injuries: none; commercial; airplane ratings: single-engine land; medical: class 2; flight hours: 2,090 total, 240 in this make and model, 117 in the last 90 days, 45 in the last 30 days, 1 in the last 24 hours

## Weather

- Conditions: Visual (VMC), Day

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.
