## Sequence of events

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

## Analysis

The student pilot reported that he took off and maneuvered into the left traffic pattern. On final, the airplane was configured with 30 degrees of flaps with an approach speed of 70 knots. His flight instructor who was observing noted that during his first landing the nose wheel came in contact with the surface first, then his two main wheels, subsequently the airplane porpoised three times, the student pilot initiated a go-around, and landed without further incident. As a result of the hard landing, the flight instructor conducted a post flight inspection of the engine and airframe, substantial damage to the firewall was discovered. The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
