## Probable cause

THE INSTRUCTOR PILOT'S FAILURE TO MAINTAIN CREW COORDINATION IN THE COCKPIT, AND THE STUDENT PILOT'S PREMATURE RETRACTION OF THE FLAPS DURING A CRITICAL MANEUVER. FACTORS WERE THE CERTIFIED FLIGHT INSTRUCTORS INADEQUATE SUPERVISION AND THE INADVERTENT LOW ALTITUDE STALL.

## 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)
  - supervision - inadequate, pilot in command(cfi) (contributing factor)
  - flight control,flap - improper
  - raising of flaps - premature, dual student (cause)
  - stall - inadvertent, pilot in command(cfi) (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

DURING AN INSTRUCTIONAL FLIGHT AT 20 FEET ABOVE THE RUNWAY THE INSTRUCTOR PILOT WAS DEMONSTRATING MINIMUM AIRSPEED FLIGHT. DURING THE RECOVERY PHASE THE STUDENT PILOT RETRACTED THE FLAPS WITHOUT INSTRUCTION FROM THE INSTRUCTOR PILOT OR WITHOUT PROVIDING HIM WITH ADVANCED WARNING. THE ACTIONS OF THE STUDENT PILOT RESULTED IN THE INSTRUCTOR PILOT LOSING CONTROL AND IMPACTING THE GROUND RESULTING IN SUBSTANTIAL DAMAGE.
