Probable cause
The flight instructor’s failure to use carburetor heat during the approach while operating in atmospheric conditions that were conducive to carburetor icing, which resulted in a loss of engine power due to carburetor icing.
Findings · 5
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 flight instructor in the multiengine airplane reported that, during a simulated single-engine instrument approach to runway 2, the right engine was configured for the simulated failure. The instructor added that the goal was to perform a missed approach on one engine and note the airplane's performance. The pilot under instruction descended to the decision height and executed the missed approach procedure, but the airplane would not climb. The flight instructor told the pilot to go to full power on both engines. According to the flight instructor, "mixtures, props and throttles were all full forward and the fuel flow levers were both at the ON position," and he took control of the airplane. The flight instructor reported that there were trees and buildings to the north and that he made a left turn about 400 ft above ground level with the intent to land on runway 14. He extended the landing gear but realized that he would not reach the runway. He executed a forced landing to the southwest on taxiway Sierra, the airplane crossed over runway 32/14, and although heavy braking was applied, the airplane exited the taxiway and impacted a drainage culvert. The airplane sustained substantial damage to the aft fuselage stringers and longerons. The airport elevation was 488 ft, the density altitude was 2,120 ft, the temperature was 81°, the dew point was 66° F, and the wind was calm, and the flight instructor stated that carburetor heat was not used during the approach on either engine. The relative humidity was about 60 percent, and the weather conditions were conducive to serious icing probability when operating in a gliding flight profile.
Factual narrative
The flight instructor in the multi-engine airplane reported that during a simulated single-engine instrument approach to runway 2, the right engine was configured for the simulated failure. The instructor reported that the goal was to perform a missed approach on one engine and note the airplane's performance. The pilot under instruction descended to the decision height and executed the missed approach procedure, but the airplane would not climb. The flight instructor told the pilot to go to full power on both engines. "Mixtures, props and throttles were all full forward and the fuel flow levers were both at the ON position," according to the flight instructor, and he took control of the airplane. The flight instructor reported that there were trees and buildings to the north and he made a left turn about 400 feet above ground level with the intent to land on runway 14. He extended the landing gear; but realized that he would not make the runway. He executed a forced landing to the southwest on taxiway Sierra, the airplane crossed over runway 32-14, and although heavy braking was applied, the airplane exited the taxiway and impacted a drainage culvert. The airplane sustained substantial damage to the aft fuselage stringers and longerons. The airport elevation was 488 feet, the density altitude was 2,120 feet, the temperature was 81° and the dew point was 66° F, the wind was calm, and the flight instructor stated that carburetor heat was not used during the approach on either engine. Per the AOPA Carburetor Ice Probability Chart, the relative humidity was about 60 percent and there was serious icing probability when operating in a gliding flight profile.
