## Probable cause

THE PILOT'S AND COMPANY'S DISREGARD OF HAZARDOUS WEATHER CONDITIONS AND THE PILOT'S FAILURE TO MAINTAIN CONTROL OF THE AIRPLANE. CONTRIBUTING TO THE ACCIDENT WERE THE GUSTY CROSSWIND CONDITIONS.

## Sequence of events

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

- Loss of control - on ground/water, taxi - from landing
  - weather condition - crosswind (contributing factor)

  - hazardous weather advisory - disregarded, company/operator management (cause)
  - directional control - not maintained, pilot in command (cause)
- Dragged wing,rotor,pod,float or tail/skid, taxi - from landing

## Analysis

DURING THE POST-LANDING TAXI, A STRONG LEFT CROSSWIND LIFTED THE LEFT WING CAUSING THE AIRPLANE TO MAKE AN UNCONTROLLED 270 DEGREE RIGHT TURN, DURING WHICH THE RIGHT WING TIP AND PROPELLER STRUCK THE GROUND. THE WINDS WERE REPORTED TO BE 28 KTS GUSTING TO 44 KTS.
