A solo private pilot experienced a total loss of engine power at about 200 feet AGL, switched fuel tanks, and performed a forced landing on a sandy river bank. The airplane nosed over during the landing roll, sustaining substantial damage. Postaccident inspection revealed the main wheels were locked due to a brake system issue.

Incident Overview

A solo private pilot reported a loss of all engine power while in cruise flight at approximately 200 feet above ground level. The pilot stated that the fuel selector valve was positioned on the right fuel tank and that he intended to run the right tank dry before switching tanks. As the engine began to lose power, he moved the selector to the left fuel tank, but engine power was not immediately restored.

Forced Landing and Nose-Over

The pilot selected a forced landing area on a sandy river bank. During the landing roll, without applying the brakes, the airplane slowly nosed over. The airplane sustained substantial damage to the left wing lift strut and rudder.

Brake System Issue

The pilot noted that just prior to the accident flight, he added hydraulic brake fluid to the brake system. In his written report, he indicated that a postaccident inspection revealed the main wheels would not rotate. When he bled the hydraulic brake system, both air and pressurized hydraulic fluid escaped from the bleed valve. After bleeding the hydraulic system, both wheels operated normally.

Damage and Pilot Actions

The aircraft received substantial damage to the left wing lift strut and rudder. The pilot was the sole occupant. No further information about injuries or aircraft specifications was provided in the report.

Investigation Findings

The source does not state a probable cause. The events are based solely on the pilot's account and postaccident inspection results.
