## Probable cause

THE FAILURE OF THE PILOT TO MAINTAIN PROPER ALIGNMENT WHILE LANDING ON WATER, RESULTING IN A SWERVE DURING DECELERATION.

## 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 - roll
  - proper alignment - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command (cause)
  - terrain condition - water
- On ground/water encounter with terrain/water, landing - roll

## Analysis

WHILE LANDING ON A LAKE, THE ACFT SWERVED DURING DECELERATION AND THE WINGS IMPACTED THE WATER.

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.
