## Sequence of events

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

- Loss of control - in flight, go-around (vfr)
  - emergency procedure - simulated, pilot in command(cfi) (cause)
  - in-flight planning/decision - poor, pilot in command(cfi) (cause)
  - go-around - misjudged, pilot in command(cfi) (cause)
  - stall - not corrected, pilot in command(cfi) (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE CFI GAVE THE STUDENT A SIMULATED FORCED LANDING AND THE STUDENT SPIRALED DOWN TO 400 FT AGL. WHEN THE CFI SAID 'I'VEGOT THE AIRPLANE' THE ACFT NOSE CAME UP AND THE ACFT STARTED TO SETTLE. THE CFI STATED HE APPLIED POWER BUT THE ACFT CONTINUED TO SETTLE, STALLING INTO A SUGAR CANE FIELD. THE CFI BLAMED THE ACCIDENT ON THE SLOW RESPONSE OF THE ENGINE. THE ENGINE WAS FUNCTIONALLY CHECKED AND NO DISCREPANCIES WERE FOUND.
