The flight instructor reported that he was going to demonstrate a simulated engine failure on takeoff for a student pilot. After climbing several hundred feet, he reduced the engine power to idle and pitched the airplane to maintain best glide speed. He applied back pressure to the yoke during the landing flare and realized they were going to land harder than desired. The airplane touched down hard on the runway.

The airplane sustained substantial damage to both wings.

The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
