## Probable cause

A total loss of engine power due to oil starvation to the rear crankshaft journal.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

## Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event best describes what happened.

- [Enroute: Loss of engine power (total)](https://openairdocs.org/ntsb-events/341) (defining event); cases with it: [Rudolph Ralph Monroe STARLITE, 1 case](https://openairdocs.org/ntsb-events/341/sequence.md?model=05612BU), [All aircraft, 3,820 cases](https://openairdocs.org/ntsb-events/341/sequence.md)
- [Emergency descent: Off-field or emergency landing](https://openairdocs.org/ntsb-events/440); cases with it: [Rudolph Ralph Monroe STARLITE, 1 case](https://openairdocs.org/ntsb-events/440/sequence.md?model=05612BU), [All aircraft, 3,365 cases](https://openairdocs.org/ntsb-events/440/sequence.md)

## Analysis

During a local personal flight, the engine of the amateur-built airplane lost power without warning. The pilot looked for a field to land in, but overshot the field and impacted desert terrain. During the crash sequence, the aircraft sustained substantial damage to both of the wings, the landing gear, and the firewall. Examination of the engine found that the rear connecting rod at the crankshaft journal was separated and exhibited severe heat distress signatures consistent with oil starvation to the bearing. The respective crankshaft journal displayed a dark black/blue coloration consistent with heat distress. The forward crankshaft journal and connecting rod remained undamaged.

## Factual narrative

During a local personal flight the engine lost power without warning. The pilot looked for a field to land in, but overshot the field and impacted desert terrain. During the crash sequence, the aircraft sustained substantial damage to both of the wings, the landing gear, and the firewall. The National Transportation Safety Board investigator-in-charge examined the engine and found the rear connecting rod at the crankshaft journal was separated and exhibited severe heat distress signatures consistent with lubrication depravation. The respective crankshaft journal displayed a dark black/blue coloration consistent with heat distress. The forward crankshaft journal and connecting rod remained undamaged.

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.
