Narrative:

I had filed an IFR flight plan with vectors to the wausau VOR direct oshkosh VOR V191 badger VOR direct east troy. I had obtained a void time for a departure within 15 mins to contact ZMP once airborne. My concern was to set up navigation and communication aids as I had started my aircraft engine. The conditions outside were a down pouring rainfall which was effecting my forward visibility as the propeller was spinning. I hadn't realized that in the confined area where my aircraft was parked and started that it had rolled forward an estimated 20 ft causing my propeller to strike a lower exposed aircraft fuel pump farm exterior cover only. I realize I was in a confined area and should have paid obviously better attention to taxiing clear of a known obstruction and then to have setup related navigation and communication concerns once clear. Especially when outside visibility is compromised.

Title: SMA, BLINDED BY DRIVING RAIN SHOWER, ALLOWS ACFT TO ROLL INTO FUEL PUMP.

Narrative: I HAD FILED AN IFR FLT PLAN WITH VECTORS TO THE WAUSAU VOR DIRECT OSHKOSH VOR V191 BADGER VOR DIRECT EAST TROY. I HAD OBTAINED A VOID TIME FOR A DEP WITHIN 15 MINS TO CONTACT ZMP ONCE AIRBORNE. MY CONCERN WAS TO SET UP NAV AND COM AIDS AS I HAD STARTED MY ACFT ENG. THE CONDITIONS OUTSIDE WERE A DOWN POURING RAINFALL WHICH WAS EFFECTING MY FORWARD VISIBILITY AS THE PROP WAS SPINNING. I HADN'T REALIZED THAT IN THE CONFINED AREA WHERE MY ACFT WAS PARKED AND STARTED THAT IT HAD ROLLED FORWARD AN ESTIMATED 20 FT CAUSING MY PROP TO STRIKE A LOWER EXPOSED ACFT FUEL PUMP FARM EXTERIOR COVER ONLY. I REALIZE I WAS IN A CONFINED AREA AND SHOULD HAVE PAID OBVIOUSLY BETTER ATTN TO TAXIING CLR OF A KNOWN OBSTRUCTION AND THEN TO HAVE SETUP RELATED NAV AND COM CONCERNS ONCE CLR. ESPECIALLY WHEN OUTSIDE VISIBILITY IS COMPROMISED.
