At 09:00 CST, a Cessna 152 lost power and was damaged in a forced landing near Odessa. The instructor was not injured and the student reported minor injuries. The instructor was demonstrating emergency procedures. During a simulated loss of power, the engine actually did quit and the propeller stopped. The instructor took control of the airplane and attempted to re-start the engine, without success. He then conducted a forced landing, and on touchdown the nosewheel dug into rough terrain and resulted in substantial damage to the airplane. No mechanical problems with the engine were found and fuel was present in the fuel lines. The engine was test run after the accident without problems.
