A flight from Anchorage experienced two episodes of engine roughness. After carburetor heat initially smoothed the engine, a later application caused rougher operation, leading to a crash landing near Peter's Creek.

Flight History

The flight originated from Anchorage, Alaska, at approximately 1400 AST. While flying near Knik Glacier, the pilot observed sheep and circled the area twice. During the second turn, the engine began running erratically. The pilot reportedly applied carburetor heat, and the engine smoothed out. He then diverted to Palmer, where the engine was checked and operated normally. Afterward, he departed Palmer and continued to Wasilla, Alaska, where he landed for a coffee break.

At approximately 1550, the flight departed Wasilla for the return trip to Anchorage. The pilot reported climbing to 3,500 feet MSL. After crossing the Knik Arm, he proceeded along the mountains. In the vicinity of Peter's Creek, the engine began running rough. The pilot applied carburetor heat, but the engine ran rougher, so he discontinued its use. Subsequently, the aircraft lost airspeed, and the pilot executed a crash landing.

Environmental Conditions

The temperature and dew point were 40°F and 23°F, respectively. According to icing probability charts, visible icing was probable at cruise or gliding power.

Outcome

The aircraft sustained damage during the crash landing. No injuries or fatalities were reported in the source.
