Engine Power Loss During Climb After Power Reduction Leads to Off-Runway Impact (N8677C)

Chugiak, AK, US

On April 4, 1989, a Piper PA-18 (registration N8677C) operated by Charles H. Dowrick was involved in an aviation accident near Chugiak, AK. Investigators recorded the probable cause as: CARBURETOR ICE DUE TO THE PILOT'S IMPROPER USE OF POWERPLANT CONTROLS; AND FAILURE OF THE PILOT TO MAINTAIN ADEQUATE AIRSPEED, WHILE MANEUVERING (TURNING LEFT), WHICH RESULTED IN AN INADVERTENT STALL. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

During climb at 20-30 ft AGL, the pilot reduced power and the engine lost power without warning. Turning left 110 degrees, the aircraft impacted frozen terrain, slid 96 ft, and came to rest 175 ft east of the runway.

Accident Sequence

The pilot reported that while the aircraft was climbing at an altitude of about 20 to 30 feet above ground level (AGL), he made a power reduction. Immediately thereafter, the engine lost power without warning. Uncertain whether he could clear a fence ahead, the pilot executed a left turn of approximately 110 degrees. Subsequently, the aircraft impacted relatively flat, frozen terrain. It slid 96 feet and came to rest approximately 175 feet east of the runway.

Post-Accident Examination

The broken carburetor was removed and disassembled. No preimpact part failure or noticeable contamination was found. The engine was operationally checked; it started and operated with no problems that would have caused the accident.

Environmental Conditions

The temperature and dew point were 36 degrees Fahrenheit and 27 degrees Fahrenheit, respectively. According to carburetor ice charts, conditions were conducive to carburetor ice formation.

Takeoff Details

The accident occurred after the pilot had initiated an intersection takeoff with about 1960 feet of runway remaining.
