## 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 - aerial application
  - engine assembly,cylinder - cracked (cause)
  - lubricating system,oil line - separation (cause)
- Forced landing, landing - flare/touchdown
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ditch (contributing factor)
  - terrain condition - rough/uneven (contributing factor)
- Nose over, landing - roll

## Analysis

THE AIRCRAFT COLLIDED WITH A DITCH DURING A FORCED LANDING AFTER POWER LOSS WHILE ON AN AERIAL APPLICATION FLIGHT. THE ENGINE FAILED BECAUSE OF LOSS OF #2 CYLINDER. THE CYLINDER HEAD CRACKED AND RUPTURED TWO OIL LINES. WITH THE WINDSHIELD COVERED WITH OIL AND THE ENGINE POWER LOST THE PILOT MADE A FORCED LANDING IN A NEARBY FIELD. THE PILOT'S FORWARD VISIONWAS BLOCKED BY THE OIL-COVERED W/SHIELD.

## 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 19830411014079A](https://openairdocs.org/incident/19830411014079A), Apr 11, 1983: Scwzer G164A, Lexington, NC, Substantial damage. Aircraft collided with ditch and flipped over during forced landing. Cylinder head cracked during spray run turn.

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.
