Analysis

The airplane's descent was uneventful. The wind was reported as 300 degrees at 19 knots gusting to 25 knots. After touchdown, the airplane porpoised. The pilot then taxied the airplane to the hangar. Although the landing was very rough, the pilot was unaware that the airplane was damaged. Post-flight examination revealed that the propeller blades were slightly bent to the rear, and the firewall was dented.
