A floatplane's right float sustained strut damage after turbulence during landing flare led to the right float tip submerging; prop strike caused metal fragments to pierce the left float, resulting in both floats sinking and engine submersion.

Incident Overview

The pilot of a floatplane reported that during the landing flare, the aircraft encountered turbulence and touched down on the right float. This uneven contact caused the right float's tip to submerge, leading to bending of the struts on that float.

Sequence of Events

Following the touchdown on the right float, the aircraft continued forward. The propeller then struck the right float, generating metal fragments that pierced the left float. Subsequently, both floats lost buoyancy and sank, allowing the engine to become submerged in the water.

Damage Assessment

The right float struts were bent, and the propeller incurred damage from cutting into the float. The left float was punctured by metal pieces from the right float. The sinking of the floats resulted in the engine being submerged.

No further details regarding the aircraft type, registration, operator, location, date, or occupants were provided in the source.
