Narrative:

I was flying to granby, co, on a ski trip. I flew over the winter park area and then headed north to the granby airport using the LORAN to navigation. At 2 mi out I saw an airport with 3 hangars, a wind sock, and red clearance balls on the high wires. It was an ultralight airport that also rented snow mobiles. The snow mobiles would run down the runway jump the ditch and continue on, making the runway look much longer from the air than it really is. The runway also runs in the same e-w direction adding to the misident problem between the ultralight airport and granby airport. The ultralight airport is not shown on the chart so it is easy to conclude that it is granby airport. When on final at the higher altitude I didn't want to do a missed approach or a go around so I landed at the ultralight airport doing damage to the nosewheel on my aircraft.

Title: PLT OF SMA LANDED ON UNMARKED, NON CHARTED ULTRALIGHT ARPT THINKING IT WAS GRANBY, CO, ARPT.

Narrative: I WAS FLYING TO GRANBY, CO, ON A SKI TRIP. I FLEW OVER THE WINTER PARK AREA AND THEN HEADED N TO THE GRANBY ARPT USING THE LORAN TO NAV. AT 2 MI OUT I SAW AN ARPT WITH 3 HANGARS, A WIND SOCK, AND RED CLRNC BALLS ON THE HIGH WIRES. IT WAS AN ULTRALIGHT ARPT THAT ALSO RENTED SNOW MOBILES. THE SNOW MOBILES WOULD RUN DOWN THE RWY JUMP THE DITCH AND CONTINUE ON, MAKING THE RWY LOOK MUCH LONGER FROM THE AIR THAN IT REALLY IS. THE RWY ALSO RUNS IN THE SAME E-W DIRECTION ADDING TO THE MISIDENT PROBLEM BTWN THE ULTRALIGHT ARPT AND GRANBY ARPT. THE ULTRALIGHT ARPT IS NOT SHOWN ON THE CHART SO IT IS EASY TO CONCLUDE THAT IT IS GRANBY ARPT. WHEN ON FINAL AT THE HIGHER ALT I DIDN'T WANT TO DO A MISSED APCH OR A GAR SO I LANDED AT THE ULTRALIGHT ARPT DOING DAMAGE TO THE NOSEWHEEL ON MY ACFT.
