## Sequence of events

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

- Loss of engine power(partial) - mech failure/malf, maneuvering - aerial application
  - fluid,oil - starvation (cause)
  - engine assembly,bearing - failure,total (cause)
  - eng assembly,blower/impeller/integral supercharger - failure,partial (cause)
- Forced landing, descent - emergency
- Nose over, landing - roll

## Analysis

AS A RESULT OF A SUPERCHARGER FAILURE, A PARTIAL POWER LOSS WAS EXPERIENCED DURING A SWATH RUN. DURING THE LANDING ROLL AFTER A FORCED LANDING, THE ACFT NOSED OVER & CAME TO REST INVERTED. AN ENG TEARDOWN REVEALED THAT BOTH SUPERCHARGER BEARINGS HAD FAILED DUE TO LACK OF LUBRICATION.

## 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 19840717033349A](https://openairdocs.org/incident/19840717033349A), Jul 17, 1984: Scwzer G164B, Roe, AR, Substantial damage. Engine siezed due to lack of lubrication during a spray run. Flipped over on forced landing. Oil lack unexplained.

## Other investigations on N8365K (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.
