The defining event best describes what happened. - [Landing: Landing area undershoot](https://openairdocs.org/ntsb-events/370) (defining event); cases with it: [Piper PA-28R-200, 2 cases](https://openairdocs.org/ntsb-events/370/sequence.md?model=7102811), [All aircraft, 201 cases](https://openairdocs.org/ntsb-events/370/sequence.md) - [Landing: Hard landing](https://openairdocs.org/ntsb-events/092); cases with it: [Piper PA-28R-200, 14 cases](https://openairdocs.org/ntsb-events/092/sequence.md?model=7102811), [All aircraft, 2,102 cases](https://openairdocs.org/ntsb-events/092/sequence.md) ## Analysis The commercial pilot was taking a practical test to become a flight instructor and was demonstrating a simulated short field landing over a simulated 50-foot obstacle. The commercial pilot reported that he had planned to touch down on or within 100 feet past the numbers painted on the runway. The painted numbers were 60 feet long and about 18 feet from the approach end of the runway. The airplane touched down short of the intended landing spot, and the right main landing gear struck the edge of the runway surface, causing a loud “bang” that both the commercial pilot and the pilot examiner reported hearing. A postflight examination showed that the hard landing caused substantial damage to the right wing when three wing ribs separated from the spar web and partially penetrated through the upper skin. The commercial pilot added that the accident could have been avoided if he had picked a touchdown spot further away from the approach end of the runway. ## Factual narrative The commercial pilot was taking a practical test and was demonstrating a simulated short field landing over a simulated 50 foot obstacle.
