## Probable cause

A COMPLETE POWER LOSS FROM MECHANICAL FAILURE.  A FACTOR WAS: A POND, WHICH THE AIRCRAFT ENTERED DURING LANDING ROLL.

## 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, cruise - normal
  - ignition system,magneto - shorted (cause)
  - exhaust system,turbocharger - failure,total (cause)
- Forced landing, descent - emergency
- Nose over, landing - roll
  - terrain condition - open field
  - terrain condition - water (contributing factor)

## Analysis

DURING CRUISE FLIGHT, THE ENGINE BEGAN TO RUN ROUGH FOLLOWED BY A COMPLETE POWER LOSS.  A FORCED LANDING WAS MADE IN A FIELD AND DURING LANDING ROLL, THE AIRCRAFT WENT INTO A POND AND NOSED OVER.  EXAMINATION REVEALED A SHORTED RIGHT MAGNETO AND MECHANICAL FAILURE OF THE TURBOCHARGER.

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

- [Accident 19930302004129A](https://openairdocs.org/incident/19930302004129A), Mar 2, 1993: Cessna T210N, Walsh, CO, Substantial damage. Lost power en route. Landed in a pond and nosed over. Magneto shorted out and turbocharger bearing had failed.

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.
