Location: Port Aransas, Texas 
Accident Number: CEN22LA094
Date and Time: January 1, 2022, 17:15 Local 
Registration: N8816T
Aircraft: Cessna 182C 
Aircraft Damage: Substantial
Defining Event: Fuel related
Injuries: 1 Minor
Flight Conducted Under: Part 91: General aviation - Skydiving

Analysis

The pilot reported that he was returning to land after dropping a load of skydivers at 10,000 ft above mean sea level, and that he did not apply carburetor heat during the descent. He reduced the throttle to idle when he entered an extended based leg of the traffic pattern. The approach path was low, so the pilot increased the throttle, but the engine did not respond. He completed steps to troubleshoot the loss of power, but he did not apply the carburetor heat. The pilot made a forced landing to a marshy area; the airplane impacted uneven terrain and sustained substantial damage to the left wing. Examination of the fuel system did not reveal any anomalies that would have precluded normal operation. The atmospheric conditions at the time of the accident were conducive to the development of serious carburetor icing at glide power. Given the evidence, it is likely that carburetor ice accumulated, which resulted in the inability to increase engine power during the final approach. According to the Federal Aviation Administration, the airplane’s engine is highly susceptible to ice formation during a descent and the use of carburetor heat is recommended.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The loss of engine power due to carburetor icing and the pilot’s failure to utilize carburetor heat. 

Findings

Environmental issues Conducive to carburetor icing - Effect on equipment
Personnel issues Decision making/judgment - Pilot

Preventing Similar Accidents

Preventing Carburetor Icing

Accident involving carburetor ice stem for pilots not recognizing when weather conditions are favorable to carburetor icing and inaccurately believing that carburetor icing is only a cold- or wet-weather problem. Pilots also may not use the carburetor heat according the aircraft's approved procedures to prevent carburetor ice formation. Carburetor icing accident can occur when pilots do not recognize and promptly act upon the signs of carburetor icing.

Be sure to check the temperature and dew point to determine whether the conditions are favorable for carburetor icing. Remember, serious carburetor icing can occur in ambient temperatures as high as 90° F or in relative humidity conditions as low as 35 percent at glide power. Consider installing a carburetor temperature gauge, if available.

Refer to the approved aircraft flight manual or operating handbook to ensure that carburetor heat is used according to the approved procedures and properly perform the following actions: 1) Check the functionality of the carburetor heat before flight. 2) Use carburetor heat to prevent the formation of carburetor ice when operating in conditions and at power settings in which carburetor icing is probable. Remember, ground idling or taxiing time can allow carburetor ice to accumulate before takeoff. 3) Immediately apply carburetor heat at the first sign of carburetor icing, which typically includes a drop in rpm or manifold pressure (depending upon how your airplane is equipped). Engine roughness may follow.

Engines that run on automobile gas may be more susceptible to carburetor icing than engines that run on Avgas.
