Borrego Valley Airport
Aircraft Accident/Incident Report
Borrego Springs, California 92004
Saturday, October 28, 1995 9:27 PDT
NTSB Narrative Summary Released at Completion of Accident
The pilot stated that while descending for landing he applied carburetor heat. The engine rpm decreased to about 1000, and subsequently could not be adjusted by the pilot. The pilot then elected to land on a dirt area in a landfill southeast of the airport. The nose gear collapsed rearward during the landing on the uneven terrain. Straw debris was found surrounding the heat muff leading to the carburetor air box. Similar debris was also found in a large quantity inside the air box behind the air cleaner bracket. The temperature was 67 and the dew point 53 degrees Fahrenheit. This temperature/dew point range is in an area on the carburetor icing probability chart which is annotated for moderate carburetor icing at cruise power and serious carburetor icing at glide power.
NTSB Probable Cause Narrative
the pilot's inadequate preflight inspection which failed to detect a bird's nest in the air induction system. Factors in the accident were carburetor icing conditions and the pilot's improper use of carburetor heat.
