## Probable cause

AN INADVERTANT LANDING GEAR EXTENSION AND WHEELS DOWN WATER LANDING BY THE PILOT IN COMMAND.  A FACTOR RELATING TO THE ACCIDENT WAS THE LACK OF CHECKLIST USE BY THE PILOT.

- Nose over, landing - flare/touchdown
  - wheels down landing in water - inadvertent, pilot in command (cause)
  - checklist - not used, pilot in command (contributing factor)
