BE55 PILOT REPORTS BEING STRUCK BY WIND FARM PROPELLER BLADES WHILE ATTEMPTING TO MAINTAIN VFR 10 NM NORTH OF DEST.

Narrative

I WAS FLYING ON VFR PLAN. ABOUT 20 MI FROM MY DEST; ATC ASKED ME TO FLY PARALLEL TO THE RWY BUT TO THE N BY ABOUT 10 MI TO AVOID IFR TFC ON DIRECT APCH. THE CONDITIONS WERE GOOD VFR ON TOP OF ISOLATED FOG IN MY AREA BUT CLR OVERHEAD THE ARPT. I LISTENED TO ATIS WHO GAVE 1300 FT CEILING AND 10 MI AND ONCE PAST A TALL MAST 1000 FT I DSNDED TO 1000 FT EXPECTING TO SEE THE GND CLEARLY AT ANY MOMENT. I SAW IT FROM TIME-TO-TIME AND CONTINUED TO DSND AND AT 500 FT ON THE ALTIMETER; NOT SEEING THE GND CLEARLY; I REALIZED HOW LOW I WAS AND INITIATED A CLB. JUST AFTER; I SAW THE LARGE PROP OF A WIND FARM AND A SECOND LATER I HIT IT WITH THE L WING AND A FRACTION OF A SECOND LATER HIT THE R WING ON AN ADJACENT PROP. THE BLOWS WERE AT THE EXTREMITY OF THE WINGTIPS. THE AIRPLANE FLEW NORMALLY AND I LANDED WITHOUT ANY CTL PROBS. THE DAMAGE TO THE ACFT IS MINIMAL AND REQUIRES REPLACEMENT OF 2 WINGTIPS. I INFORMED THE ARPT POLICE AND THE AUTHS. THE WINGTIPS HAVE BEEN RECOVERED AND ON PRELIMINARY INSPECTION NO DAMAGE HAS BEEN SEEN ON THE WIND FARM PROPS.
