Aircraft Accident/Incident Report
Glenwood Spring, Colorado 81601
Saturday, October 23, 2004 11:05 MDT
NTSB Narrative Summary Released at Completion of Accident
Prior to the accident, the pilot had been flying for approximately 1 hour. He stated that he descended from approximately 8,500 feet msl at an engine power setting of 2,200 rpm, without carburetor heat. This descent lasted approximately 20 to 30 minutes as he flew from west to east, approximately 60 miles. The pilot entered the traffic pattern at approximately 7,000 feet msl. He applied carburetor heat, enrichened the mixture "somewhat", and reduced power to approximately 1,500 to 1,700 rpm, "prepatory for landing." The aviation routine weather report (METAR) reported the temperature as 34 degrees Fahrenheit (F) and the dewpoint as 31 degrees F. According to the carburetor icing chart, conditions were conducive for "serious icing at cruise power."According to the pilot, he was on final approach when he "decided [the] aircraft [was] too high" and added throttle to initiate a go-around. The engine did not respond to the application of throttle. The airplane impacted the roof of a townhouse, slid down and subsequently impacted the side of an adjacent townhouse causing substantial damage to the airplane.
NTSB Probable Cause Narrative
the pilot's failure to use carburetor heat which resulted in the formation of carburetor ice and the loss of engine power. Related factors were conditions conducive for carburetor icing and the lack of suitable terrain for a forced landing.
