## Probable cause

THE STUDENT PILOT'S FAILURE TO MAINTAIN CONTROL OF THE AIRPLANE DURING LANDING.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - on ground/water, landing - roll
  - airspeed - misjudged, pilot in command (contributing factor)
  - porpoise/pilot-induced oscillation - inadvertent, pilot in command (contributing factor)
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command (contributing factor)
- Nose over, landing - roll

## Analysis

THE STUDENT PILOT WAS OBSERVED TO LAND TOO FAST, BALLOON, PORPOISE, DEPART THE SIDE OF THE RUNWAY, AND FLIP OVER IN THE GRASS.

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.
