## Probable cause

THE PILOT'S INADVERTENT LOWERING OF THE WHEELS DURING THE WATER LANDING.

## Sequence of events

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

- Nose over, landing - flare/touchdown
  - terrain condition - water
  - gear extension - inadvertent, pilot in command (cause)

## Analysis

THE PILOT INADVERTENTLY LOWERED THE LANDING WHEELS INSTEAD OF LOWERING THE FLAPS DURING THE LANDING APPROACH.  THE AMPHIBIAN AIRPLANE SUBSEQUENTLY NOSED OVER UPON TOUCHDOWN ON THE ST. CROIX RIVER.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
