Probable cause

The pilot’s failure to apply carburetor heat in conditions conducive to carburetor icing, which resulted in a partial loss of engine power during landing.

Findings · 4

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that the airplane departed with 10 gallons of fuel to practice crosswind landings at a nearby airport. He added that, about 1 hour later and during an approach, he was aiming to land on the runway numbers. He reported that, shortly before flying over the airport perimeter fence, "either wind shear or [a] sudden downdraft dropped the plane." The nose landing gear struck the fence, and the airplane impacted the ground short of the intended runway. In a followup interview with the National Transportation Safety Board investigator-in-charge, the pilot reported that, during approach, the engine was running the entire time without issues. He added that, once he encountered the downdraft, he applied full power, but the airplane continued descending with "no appreciable response." He reported that he did not use carburetor heat during the approach. The airplane sustained substantial damage to the fuselage and horizontal stabilator. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. A review of recorded data from the automated weather observation station located on the airport revealed that, about the time of the accident, the wind was from 210° at 8 knots, visibility 10 statute miles, clouds overcast at 1,100 ft, temperature 68°F, dew point 63°F, and altimeter 29.96 inches of mercury. The airplane was landing on runway 22. Review of the Federal Aviation Administration Carburetor Icing Chart for the given temperature and dew point revealed that the conditions were conducive to "serious icing (glide power)." (For more information, see Special Airworthiness Information Bulletin CE-09-35 in the public docket.)
