## Probable cause

THE PILOT-IN-COMMAND'S NOT FOLLOWING PROCEDURES/DIRECTIVES.

## Sequence of events

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

- Dragged wing,rotor,pod,float or tail/skid, landing
  - preflight planning/preparation - poor, pilot in command (contributing factor)
  - procedures/directives - not followed, pilot in command (cause)
  - terrain condition - water,rough (contributing factor)
  - porpoise/pilot-induced oscillation - not corrected, pilot in command (contributing factor)
- Nose over, landing - flare/touchdown

## Analysis

WAVES ON THE LAKE WERE RUNNING TWO TO THREE FEET WHEN THE PILOT OF THE AMPHIBIAN AIRPLANE ATTEMPTED TO LAND.  THE AIRPLANE PORPOISED ON INITIAL TOUCHDOWN AND THE PORPOISING CONTINUED WITH EACH BOUNCE BECOMING MORE SEVERE. THE LAST ENTRY INTO THE WATER WAS ON THE NOSE OF THE AIRPLANE. THE BOW OF THE HULL COLLAPSED AFT, THE AIRPLANE INVERTED, AND BEGAN TO SINK.  THE OWNERS MANUAL STATED, 'NOTE THAT THE TEAL IS FAA APPROVED FOR OPERATION IN 12 INCH WAVES.'

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.
