The flight departed Memphis International Airport (MEM) at 02:38 for a training flight in the area. During a demonstration procedure for loss of engine power, the check airman reduced the power lever to idle, turned on the ignition, and un-stowed and advanced the emergency power lever (EPL). The check airman felt a vibration and then heard a noise. He re-stowed the EPL and advanced the engine power lever. Flames exited the exhaust and the check airman shut down the engine, and made an emergency landing on Highway 61 near the Dundee exit. After landing the airplane the two pilots attempted to remove the airplane from the roadway, and a passing 18-wheeler truck struck the left wing of the airplane.

Probable Cause:

PROBABLE CAUSE: "The pilot's improper use of the emergency power lever which resulted in excessive operating temperatures. A factor was the improper adjustment of the emergency power lever dead band."
