The flight crew recalled that the automated surface observing system (ASOS) at the uncontrolled airport indicated that they would be landing the Learjet 55 with a “light quartering tailwind.” Then, someone radioed on the common traffic advisory frequency (CTAF) that the runway was covered with 1/4 in (0.6 cm) of dry snow. However, the U.S. National Transportation Safety Board (NTSB) determined that there actually was about an inch (2.5 cm) of snow on the unplowed runway, and that the tail wind component was nearly 8 kt.
