Factual narrative

THE PILOT OBTAINED A WX BRIEFING, FILED A FLT PLAN AND TOOK OFF ON AN IFR X COUNTRY FLT INTO AN AREA OF FORECAST MODERATE ICING CONDITIONS IN AN ACFT NOT EQUIPPED OR CERTIFIED FOR THE FLT. WHEN HE ENCOUNTERED ACFT ICING DURING THE FLT, HE REQUESTED RADAR VECTORS TO THE NEAREST AIRPORT, AND WAS CLEARED FOR AN INSTRUMENT APPROACH FOR LANDING. AFTER FLYING THE APPROACH, THE PILOT CIRCLED IN VMC WHILE SCRAPING ICE FROM THE WINDSHIELD FOR VISBY TO LAND. THE ACFT DESCENDED BELOW THE LEVEL OF THE APRT, LOCATED ON A BLUFF, AND WAS UNABLE TO CLIMB TO REACH THE RUNWAY FOR LANDING. THE ACFT IMPACTED ON THE SIDE OF THE BLUFF 1/2 MILE FROM THE RUNWAY.
