Narrative:
IFR flight from ZZZ1 to ZZZ2 in mostly VMC; some IMC; at 12000 ft. Upon nearing destination; commenced descent; during descent; temperature dropped from 7 degrees C; to -2 degrees C. Rapidly picked up ice on windshield and leading edges. Abandoned approach and requested climb back up into warmer air. Set course for new destination suggested by center and began attempts to climb. Climb was at less than 100 FPM. Nearing our new destination; ZZZ; and at 5200 ft MSL; began preparing for an approach. As we arrived over runway we saw the runway environment and set up a visual approach. Held gear and full power until over the end of the runway at low altitude; selected gear down and reduced power slightly and made an uneventful landing and rollout.

Title: AN M-20K ENTERED AND ACCUMULATED UN-FORECAST ICING WHILE DESCENDING INTO ITS DESTINATION. THE PILOT MISSED THE APPROACH AND FLEW TO HIS ALTERNATE WITH FULL POWER; GEAR UP. THE LANDING GEAR WAS EXTENDED OVER THE RUNWAY'S END.
Narrative: IFR FLT FROM ZZZ1 TO ZZZ2 IN MOSTLY VMC; SOME IMC; AT 12000 FT. UPON NEARING DEST; COMMENCED DSCNT; DURING DSCNT; TEMP DROPPED FROM 7 DEGS C; TO -2 DEGS C. RAPIDLY PICKED UP ICE ON WINDSHIELD AND LEADING EDGES. ABANDONED APCH AND REQUESTED CLB BACK UP INTO WARMER AIR. SET COURSE FOR NEW DEST SUGGESTED BY CTR AND BEGAN ATTEMPTS TO CLB. CLB WAS AT LESS THAN 100 FPM. NEARING OUR NEW DEST; ZZZ; AND AT 5200 FT MSL; BEGAN PREPARING FOR AN APCH. AS WE ARRIVED OVER RWY WE SAW THE RWY ENVIRONMENT AND SET UP A VISUAL APCH. HELD GEAR AND FULL PWR UNTIL OVER THE END OF THE RWY AT LOW ALT; SELECTED GEAR DOWN AND REDUCED PWR SLIGHTLY AND MADE AN UNEVENTFUL LNDG AND ROLLOUT.
