Pilot reported left engine lost power due to fuel exhaustion; failure to close fuel selector during crossfeed caused right engine to quit; restored power but too low to avoid hard landing on lake.

Incident Summary

An amphibian airplane made a hard landing on a small lake after experiencing a loss of power in both engines. The pilot stated that the left engine lost power due to fuel exhaustion. In an attempt to remedy the situation, he activated the fuel crossfeed but did not close the left engine's fuel selector. This caused the right engine to also cease operating. The pilot was able to restore power to the right engine, but the airplane was too low to avoid a hard landing on the lake.

Pilot Report

According to the pilot, the left engine failed during cruise flight because of fuel exhaustion. He then turned on the fuel crossfeed. However, he failed to shut off the fuel selector for the left engine. This action led to the right engine quitting as well. After restoring power to the right engine, the airplane did not have enough altitude to climb or avoid the hard impact with the lake. The airplane came to rest on the lake following the hard landing.

Probable cause

The left engine lost power due to fuel exhaustion, and the right engine lost power because the pilot failed to shut off the left engine's fuel selector when activating the fuel crossfeed.
