## Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event best describes what happened.

- [Landing: Hard landing](https://openairdocs.org/ntsb-events/092) (defining event); cases with it: [Cessna 172S, 102 cases](https://openairdocs.org/ntsb-events/092/sequence.md?model=2072439), [All aircraft, 2,102 cases](https://openairdocs.org/ntsb-events/092/sequence.md)

## Analysis

The solo student pilot reported that, while on final approach following a cross-country flight, he experienced what felt like a down draft or wind shear. The airplane touched down hard on the runway, bounced, and on the second touchdown, the nosewheel impacted the surface first. The student pilot taxied the airplane to the ramp without further incident. Postaccident examination of the airframe and engine revealed substantial damage to the firewall. The student pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. A review of recorded data from the automated weather observation station located on the airport revealed that, about 5 minutes before the accident, the wind was 040° at 5 knots. The airplane landed on runway 30.
