## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

PILOT LANDED ON RUNWAY 22, DID NOT NOTICE ANYTHING UNUSUAL ON FINAL.  DURING THE ROLL OUT AND INITIATION OF THRUST REVERSAL, PILOT'S ATTENTION WAS DIVIDED BETWEEN FLIGHT CONTROLS AND ENGINE INDICATORS AND OUTSIDE THE AIRPLANE.  PILOT NOTICED A LARGE CHUNK OF ICE IN MIDDLE OF RUNWAY, SWERVED SLIGHTLY TO LEFT TO AVOID HITTING IT WITH THE NOSEWHEEL, IT HIT THE RIGHT MAIN WHEEL INSTEAD.  RIGHT WHEEL ASSEMBLY WAS SEPARATED FROM AIRCRAFT.  RIGHT PROPELLER AND WING HIT THE GROUND CAUSING SUBSTANTIAL DAMAGE.  NO INJURIES OR FIRE.

## The NTSB's investigation of this event (1)

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.
