## Probable cause

THE CFI'S POOR IN-FLIGHT DECISION TO DEMONSTRATE THE SIMULATED ENGINE OUT EMERGENCY LANDING AT TOO LOW AN ALTITUDE AND MISJUDGING THE ALTITUDE DURING THE CIRCLING MANEUVER.

## Sequence of events

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

- In flight collision with terrain/water, maneuvering
  - terrain condition - open field
  - in-flight planning/decision - poor, pilot in command(cfi) (cause)
  - altitude - misjudged, pilot in command(cfi) (cause)

## Analysis

WHILE ON A LOCAL TRAINING FLIGHT, THE CFI ELECTED TO DEMONSTRATE A SIMULATED ENGINE OUT, EMERGENCY LANDING TO A PRIVATELY OWNED DIRT AIRSTRIP.  THE AIRCRAFT WAS TOO HIGH TO EXECUTE A STRAIGHT IN APPROACH AND THE CFI ENTERED INTO A LEFT CIRCLING TURN.  THE CFI MISJUDGED THE AIRCRAFT'S ALTITUDE AND ITS LEFT WING STRUCK THE GROUND DURING THE TURN ONTO THE FINAL APPROACH COURSE.
