## Probable cause

The pilot's selection of an unsuitable landing/taxi area.  A factor associated with the accident was weak ice.

## Analysis

The certificated airline transport pilot related that he landed on the surface of a frozen lake, and was taxiing toward the shore.  He said that as the airplane neared the shoreline, the left tire rolled over an area of grass protruding through the ice.  As the tire passed over the grass, it broke through the ice, and the left wing struck the ice.  The airplane sustained substantial damage to the left wing.

## Factual narrative

On November 28, 2000, about 1500 Alaska standard time, a tundra tire equipped Cessna 180H airplane, N8206V, sustained substantial damage while taxiing after landing on a remote lake, about 1 mile northwest of Wasilla, Alaska, at latitude 61 degrees, 37.1 minutes north, and longitude 149 degrees, 36.5 minutes west.  The airplane was being operated as a visual flight rules (VFR) personal flight under Title 14, CFR Part 91, when the accident occurred.  The solo airline transport pilot was not injured.  Visual meteorological conditions prevailed, and no flight plan was filed.  The flight originated about 1450, from a private airstrip located about 2 miles northwest of Wasilla.

During a telephone conversation with the National Transportation Safety Board investigator-in-charge on November 30, the pilot related that he landed on the surface of a frozen lake, and was taxiing toward the shore.  As the airplane neared the shoreline, the left tire rolled over an area of grass protruding through the ice.  As the tire passed over the grass, it broke through the ice, and the left wing struck the ice.  The airplane sustained substantial damage to the left wing.

The pilot did not submit a Pilot/Operator report (NTSB form 6120.1/2).
