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 said that while on a Title 14, Code of Federal Regulations Part 91 personal flight, he planned to fly over an off-airport site to inspect it before landing. After completing a low pass over the site, he advanced the throttle to climb, and all engine power was lost. The pilot selected an area of rough and uneven terrain at the departure end of the site as a forced landing area. During the forced landing, the left wing struck the ground, and the airplane sustained substantial damage. A nearby aviation weather reporting station reported atmospheric conditions suitable for carburetor icing, but the pilot stated in his written report to the NTSB that he used carburetor heat throughout the descent and approach to the site. A postaccident inspection by a Federal Aviation Administration inspector disclosed no evidence any preimpact mechanical problems.

Factual narrative

On September 19, 2008, about 1845 Alaska daylight time, a tundra tire-equipped Piper PA-19 airplane, N3267Y, sustained substantial damage during a forced landing, about 15 miles southeast of Palmer, Alaska. The airplane was being operated as a visual flight rules Title 14 Code of Federal Regulations Part 91, personal flight when the accident occurred. The commercial pilot and sole passenger sustained minor injuries. Visual meteorological conditions prevailed, and no flight plan was filed. The flight originated at the pilot's private airstrip, Wasilla, Alaska, about 1815. During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on September 20, the pilot reported that he planned to fly over his intended landing site to inspect the area before landing. He said that after completing the low pass over the site, and as he advanced the throttle to climb, all engine power was lost, and he selected an area of rough terrain at the departure end of the site as a forced landing area. During the forced landing, the left wing collided with an area of gravel-covered terrain. The airplane sustained substantial damage to the wings and fuselage. The pilot noted in his written report to the NTSB that carburetor heat was applied during the descent and approach, while maintaining 1,500 engine rpm. The closest official weather observation station is located at the Palmer Airport, about 15 miles northwest of the accident site. At 1846, an Aviation Routine Weather Report (METAR) was reporting, in part: Wind, calm; visibility, 10 statute miles; clouds and sky condition, 7,000 feet overcast; temperature, 45 degrees F; dew point, 41 degrees F; altimeter, 29.49 inHg. When the temperature and dew point are entered into a carburetor icing probability chart, the result is in the "Serious icing-cruise or climb power" category. On September 23, a Federal Aviation Administration (FAA) airworthiness inspector from the Anchorage Flight Standards District Office traveled to the pilot's private airstrip in Wasilla, and examined the airplane after it was recovered. The inspector reported that he was unable to find any preaccident mechanical problems with the airplane.
