## Probable cause

THE LOSS OF DIRECTIONAL CONTROL AS RESULT OF THE VELOCITY MINIMUM CONTROL AIRSPEED NOT BEING MAINTAINED. A FACTOR WAS THAT THE MANEUVER WAS INITIATED AT AN INADEQUATE ALTITUDE TOO LOW FOR THE PILOT TO RECOVER.

## Sequence of events

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

- Loss of control - in flight, maneuvering
  - emergency procedure - simulated, pilot in command(cfi)
  - altitude - inadequate, pilot in command(cfi) (contributing factor)
  - airspeed(vmc) - not maintained, pilot in command(cfi) (cause)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - open field
- Fire, other

## Analysis

A 250 HOUR PRIVATE PILOT WAS UNDERGOING FINAL INSTRUCTION IN PREPARATION FOR AN UPCOMING MULTIENGINE RATING CHECKRIDE.  THE AIRPLANE WAS OBSERVED ON AN EASTERLY HEADING UNDER A 3,500 CLOUD COVER.  POWER TO BOTH ENGINES WAS INTERRUPTED AND A GLIDE ESTABLISHED WITH GEAR AND FLAPS EXTENDED.  A FEW SECONDS LATER, THE POWER WAS REESTABLISHED AND A CLIMB ATTITUDE ESTABLISHED.  A SMALLER SECONDARY POWER REDUCTION WAS HEARD, AND THE AIRPLANE SNAPPED INTO A SPIN.  RECOVERY WAS INITIATED, BUT IT WAS NOT POSSIBLE DUE TO THE LOW ENTRY ALTITUDE.

## 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 19911116051889A](https://openairdocs.org/incident/19911116051889A), Nov 16, 1991: Cessna 310C, Waller, TX, Destroyed, 2 fatal. Indicates a stall spin occurred on recovery from simulated engine out with gear and flaps down. Too low for safety.

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.
