## Probable cause

THE PILOT'S DIVERSION OF ATTENTION AND INATTENTION TO THE AIRSPEED RESULTING IN THE INADVERTENT STALL MUSH. CONTRIBUTING TO THE ACCIDENT WAS INADEQUATE ALTITUDE 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
  - airspeed(vs) - inattentive, pilot in command (cause)
  - stall/mush - inadvertent, pilot in command
- In flight collision with object, descent
  - emergency procedure - attempted, pilot in command
  - altitude - inadequate, pilot in command (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - water

## Analysis

THE PLT BECAME DISTRACTED WHILE HELPING THE PASSENGER SPOT ALLIGATORS AND FAILED TO MAINTAIN AIRSPEED (VS) RESULTING IN AN INADVERTENT STALL MUSH. HE INITIATED A RECOVERY BUT DUE TO THE LOW ALTITUDE, WAS UNABLE, BEFORE THE MAIN LANDING GEAR COLLIDED WITH AN OBJECT IN THE WATER.
