## Probable cause

THE PILOT'S IMPROPER FLARE WHICH RESULTED IN A BOUNCED, HARD LANDING AND THE SUBSEQUENT LOSS OF DIRECTIONAL CONTROL.

## Sequence of events

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

- Hard landing, landing - flare/touchdown
  - weather condition - tailwind (contributing factor)
  - wrong runway - selected, pilot in command
  - terrain condition - snow covered (contributing factor)
  - flare - improper, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
- Dragged wing,rotor,pod,float or tail/skid, landing - roll

## Analysis

THE PILOT REPORTED HE FLEW OVER THE LANDING AREA THREE TIMES TO CHECK THE LANDING SURFACE CONDITION.  DURING THE LANDING TOUCHDOWN TO THE NORTH, THE AIRPLANE BOUNCED.  THE RIGHT SKI BROKE THROUGH THE CRUSTED SNOW SURFACE AND THE AIRPLANE VEERED TO THE RIGHT.  THE PILOT APPLIED LEFT RUDDER IN AN ATTEMPT TO COMPENSATE FOR THE VEER.  THE RIGHT WING OF THE AIRPLANE CONTACTED THE LANDING AREA SURFACE AND THE AIRPLANE CAME TO A STOP.  THE PILOT REPORTED THAT THE LOCAL WINDS WERE FROM THE SOUTHEAST AT 5 KNOTS.
