ANCHORAGE, AK, USA

Aircraft #1

N124LR

Cessna A185E

Analysis

The certificated private pilot, with three passengers aboard, reported that during initial descent, all engine power was lost. He said that after performing the engine emergency procedures, he was unable to restore engine power, and he selected a forced landing site that was surrounded by trees. During the forced landing, the left wing struck a stand of trees, and the airplane pivoted to the left. A postaccident investigation revealed the presence of fuel in both wing tanks, fuel lines, and the fuel manifold assembly. No mechanical defects were found with the engine. The cockpit fuel selector valve was found in the 'both' position. On September 7, 1999, the engine was operated while still mounted on the accident airplane's airframe. No anomalies were observed during its operation, and the engine produced full factory specified rpm.

The pilot said that after performing the engine emergency procedures, he was unable to restore engine power. The pilot stated that he selected a forced landing area in a slough that was surrounded by trees. During the forced landing, the left wing struck a stand of trees, and the airplane pivoted to the left. The airplane sustained substantial damage to the wings and fuselage. An on-site inspection of the airplane by the NTSB investigator-in-charge (IIC) on August 29, revealed the presence of fuel in both wing tanks, fuel lines, and the fuel manifold assembly.
