## Analysis

THE PLT OF THIS ACFT DID NOT KNOW THE RWY SURFACE CONDITION PRIOR TO AN ATTMPTED LANDING. UNICOM ADVISORIES WERE NOT AVAILABLE. DUE TO A RECENT STORM, SIX TO TWELVE INCHES OF WET SNOW OVERLYING A PATCHY LAYER OF COMPACTED SNOW EXISTED WHEN HE TOUCHED DOWN. THE ACFT SLID OFF THE RWY SHORTLY AFTER TOUCHDOWN. SUBSTANTIAL ACFT DAMAGE OCCURRED WHEN THE ACFT STRUCK A SNOWBANK ON THE EDGE OF THE RWY.
