The NTSB's narrative final · quoted from the NTSB record
The pilot said he called the tower for airport advisories when he was 10 to 12 miles north of the airport. He was given a straight in to runway 16, but he didn't remember hearing the wind direction or its velocity. He did perform a left cross wind landing, but as he touched the runway the airplane 'weather vaned to the left.' The subsequent ground loop damaged the right wing tip and dorsal fin. The pilot stated that the surface winds were in excess of 30 knots from his left rear. He said the flags at the terminal were flying straight out. The official recorded winds for Gillette-Campbell County Airport at 1755 were clear skies with winds 080 degrees at 10 knots.
