## Probable cause

THE PILOT'S FAILURE TO MAINTAIN A PROPER AIRSPEED DURING LANDING AND THE IMPROPER RECOVERY FROM A BOUNCED LANDING. FACTORS RELATED TO THE ACCIDENT WERE THE PILOT'S LACK OF TOTAL EXPERIENCE IN SEAPLANES AND THE GUSTY WIND CONDITION.

## Sequence of events

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

- Loss of control - in flight, landing - flare/touchdown
  - weather condition - crosswind
  - airspeed - improper, pilot in command (cause)
  - recovery from bounced landing - improper, pilot in command (cause)
  - lack of total experience in type of aircraft, pilot in command (contributing factor)
- Dragged wing,rotor,pod,float or tail/skid, landing - flare/touchdown
  - weather condition - gusts (contributing factor)
- Miscellaneous/other, landing - flare/touchdown

## Analysis

THE PILOT REPORTED HE FAILED TO MAINTAIN A PROPER AIRSPEED DURING THE LANDING APPROACH TO THE SOUTHEAST.  THE WINDS WERE ALSO SHIFTING FROM THE SOUTHEAST TO THE NORTHEAST DURING THE APPROACH.  THE SEAPLANE BOUNCED ON LANDING AND THE RIGHT WING CONTACTED THE WATER.  THE SEAPLANE THEN FLIPPED INVERTED.
