Analysis

According to the pilot of the Cessna 172N, while completing touch-and-go landings, the airplane bounced on the first landing. She took off again and completed another "loop" in the pattern. The pilot returned to land at the airport a second time, which was "very smooth." She taxied the airplane back to the hangar, shut down the engine, exited the airplane, and saw the propeller was bent a "small amount." The pilot was unaware of the propeller strike; she did not hear or see anything abnormal during the second takeoff and landing. An examination of the airplane by a Federal Aviation Administration inspector revealed wrinkling of the lower firewall and fuselage skin, and both propeller blades bent aft, resulting in substantial damage to the airplane.
