Narrative:

While executing an approach and landing to runway 4 at stanley county airport (6a6), the winds were reported by CTAF as being 320 at 10 gusting occasionally to 20. My decision during the approach was to abort the landing if at any time on final approach more than half rudder or half aileron were necessary to maintain alignment with the runway. These limits were never met during the approach. Upon touchdown the right main gear and nose gear were held off the runway for approximately 200' at which time all three wheels were on the ground. Approximately half aileron was held into the wind. During rollout aircraft was suddenly picked up and started off runway, full left aileron and full left rudder were applied. The aircraft continued off the runway, but was returned to a straight path parallel to the runway and in the grass. The terrain at the point of exit of the runway was level but gradually formed a drainage ditch. Before the aircraft could be stopped the nosewheel became low enough in the ditch for the propellers to strike the ground. Both propeller tips were bent. No further damage was done. This incident was evidently brought about by a wind gust after touchdown. With no way of knowing or predicting wind gusts it is hard to say what actions could prevent such an incident from happening. My instruction in crosswind lndgs during my multi-engine training helped to prevent a serious situation from ending in tragedy.

Title: LIGHT TWIN ENGINE ACFT WITH ALMOST 90 DEGREE CROSSWIND WITH WIND STRENGTH AT LIMITS OF ACFT. LOSS OF CONTROL AND ACFT DEPARTS RWY, ACFT DAMAGED.

Narrative: WHILE EXECUTING AN APCH AND LNDG TO RWY 4 AT STANLEY COUNTY ARPT (6A6), THE WINDS WERE REPORTED BY CTAF AS BEING 320 AT 10 GUSTING OCCASIONALLY TO 20. MY DECISION DURING THE APCH WAS TO ABORT THE LNDG IF AT ANY TIME ON FINAL APCH MORE THAN HALF RUDDER OR HALF AILERON WERE NECESSARY TO MAINTAIN ALIGNMENT WITH THE RWY. THESE LIMITS WERE NEVER MET DURING THE APCH. UPON TOUCHDOWN THE RIGHT MAIN GEAR AND NOSE GEAR WERE HELD OFF THE RWY FOR APPROX 200' AT WHICH TIME ALL THREE WHEELS WERE ON THE GND. APPROX HALF AILERON WAS HELD INTO THE WIND. DURING ROLLOUT ACFT WAS SUDDENLY PICKED UP AND STARTED OFF RWY, FULL LEFT AILERON AND FULL LEFT RUDDER WERE APPLIED. THE ACFT CONTINUED OFF THE RWY, BUT WAS RETURNED TO A STRAIGHT PATH PARALLEL TO THE RWY AND IN THE GRASS. THE TERRAIN AT THE POINT OF EXIT OF THE RWY WAS LEVEL BUT GRADUALLY FORMED A DRAINAGE DITCH. BEFORE THE ACFT COULD BE STOPPED THE NOSEWHEEL BECAME LOW ENOUGH IN THE DITCH FOR THE PROPS TO STRIKE THE GND. BOTH PROPELLER TIPS WERE BENT. NO FURTHER DAMAGE WAS DONE. THIS INCIDENT WAS EVIDENTLY BROUGHT ABOUT BY A WIND GUST AFTER TOUCHDOWN. WITH NO WAY OF KNOWING OR PREDICTING WIND GUSTS IT IS HARD TO SAY WHAT ACTIONS COULD PREVENT SUCH AN INCIDENT FROM HAPPENING. MY INSTRUCTION IN XWIND LNDGS DURING MY MULTI-ENGINE TRAINING HELPED TO PREVENT A SERIOUS SITUATION FROM ENDING IN TRAGEDY.
