Incident Overview
A pilot flying into Mt Pleasant Municipal Airport in Utah encountered unexpected runway conditions during a winter landing. Before departing from Salt Lake City, the pilot checked weather and airport information, which indicated visual flight rules (VFR) conditions and that the airport was open.
Arrival and Decision
Upon arrival, the pilot observed furrows of plowed snow on both sides of the runway. He noted what appeared to be a light covering of new snow on the furrows and the runway surface. However, the snow on the runway was actually 6 inches thick and covered with a crust of ice. Despite this observation, the pilot decided to proceed with the landing.
Landing and Outcome
After touchdown, the aircraft rolled normally for approximately 75 to 100 feet. The main wheels then broke through the ice crust, and the aircraft nosed over. The incident resulted in damage to the aircraft.
Investigation Findings
An investigation revealed that the airport was unmanaged and conducted no official operations during the winter months. Because the airport did not report the field condition to the Flight Service Station (FSS), the FSS was unaware of the extent of snow coverage and therefore did not issue a Notice to Air Missions (NOTAM).
