## Probable cause

THE PILOT INADVERTENTLY LANDED ON WATER WITH THE GEAR EXTENDED.

## Sequence of events

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

- Gear not retracted, landing - flare/touchdown
  - wheels down landing in water - inadvertent, pilot in command (cause)
- Nose over, landing

## Analysis

THE AMPHIBIOUS FLOAT PLANE NOSED OVER IMMEDIATELY AFTER LANDING ON WATER. THE PLT STATED THE WHEELS WERE RETRACTED, BUT THE PASSENGER SAID ALL FOUR WHEELS WERE DOWN WHEN THE ACFT TOUCHED DOWN. WHEN THE ACFT WAS PULLED FROM THE WATER, ALL WHEELS WERE IN THE DOWN POSITION. DRG A POST-ACCIDENT CHECK, ALL OF THE GEAR OPERATED PROPERLY & ALL REMAINED IN THE UP POSITION.
