## Probable cause

THE ENGINE POWER LOSS FOR UNDETERMINED REASONS AND THE LACK OF SUITABLE TERRAIN FOR A 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, takeoff - initial climb
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - none suitable (cause)
  - terrain condition - rough/uneven

## Analysis

ACCORDING TO THE OPERATOR, THE PILOT EXPERIENCED A COMPLETE POWER LOSS AFTER LIFTOFF FROM A PRIVATE AGRICULTURAL STRIP. HE SUBSEQUENTLY EXECUTED A FORCED LANDING, STRAIGHT AHEAD, INTO ROUGH TERRAIN. THE ENGINE WAS DISPOSED OF PRIOR TO THE REASON FOR THE FAILURE BEING DETERMINED. THE ENGINE HAD RECENTLY BEEN INSTALLED IN THE AIRPLANE AND HAD ACCUMULATED A TOTAL OF 2.7 HOURS SINCE MAJOR OVERHAUL.

## Factual narrative

On June 15, 1993, at approximately 1030 central daylight time, a Rockwell International S-2R, N4955X, was substantially damaged during a forced landing near Wynne, Arkansas.  The airplane had just departed on what was to have been a local aerial application flight.  There was no flight plan filed and visual meteorological conditions prevailed throughout the area.  The pilot, the sole occupant, was not injured.

According to the operator, the pilot experienced a complete power loss after liftoff from a private ag strip.  He subsequently executed a forced landing, straight ahead, into rough terrain.  The operator disposed of the wreckage prior to a determination being made as to the cause of the engine failure.  However, it was noted that there was fuel on the airplane at the time and the pilot stated that the power loss came without warning.  The engine had been recently installed and had accumulated a total of 2.7 hours since major overhaul.

## FAA reports on this event (1)

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

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.
