Aircraft Accident/Incident Report

Davenport, Washington 98122
Monday, January 3, 2005 12:45 PST

NTSB Narrative Summary Released at Completion of Accident

The flight encountered light mixed icing during descent. The airplane was in icing conditions for about 15 minutes. The pilot used the de-icing boots during the icing encounter and cycled the boots for the last time on downwind leg for landing. During the landing flare, he reduced power over the threshold about 15 feet agl, and the airplane stalled at a higher than normal airspeed resulting in a hard landing. The pilot stated that the accident could have been prevented by keeping power and airspeed up until touchdown when landing an airplane which has encountered icing conditions and retained some airframe ice.

NTSB Probable Cause Narrative

The pilot's failure to maintain adequate airspeed during landing with airframe ice, which resulted in an inadvertent stall and hard landing. Factors were the icing conditions and the airframe ice.
