Aircraft involved
Probable cause & findings
THE ACCUMULATION OF STRUCTURAL ICE AND SUBSEQUENT STALLING OF THE AIRCRAFT. THE ICING CONDITION WAS A RELATED FACTOR.
Factual narrative
THE CESSNA 208A WAS ON AN IFR FLT TO HAUL FREIGHT FROM ASPEN TO DENVER, COLORADO. MODERATE TO HEAVY ICING CONDITIONS WERE FORECAST FOR THE DENVER AREA. WHILE ON AN ILS RWY 36 APCH, THE ACFT ENCOUNTERED ICING CONDITIONS. SUBSEQUENTLY, IT ENTERED A STEEP DESCENT & CRASHED ABOUT 3 MI FROM THE APCH END OF THE RWY. NO PREIMPACT PART FAILURE OF THE ACFT WAS FOUND DURING THE INVESTIGATION. THE 1950 MST WX AT THE ARPT WAS IN PART: 800' SCATTERED, 1000' BROKEN, VIS 4 MI WITH FREZZING DRIZZLE & SNOW SHOWERS, TEMP 28 DEG, DEW POINT 25 DEG.
