## Probable cause

THE PILOT MISJUDGED THE AIRPLANE'S ALTITUDE AND THE IMPROPER BOUNCED LANDING RECOVERY PROCEDURE. CONTRIBUTING TO THIS ACCIDENT WAS THE STUDENT PILOT'S TOTAL LACK OF EXPEREINCE.

## Sequence of events

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

- Hard landing, landing - flare/touchdown
  - altitude - misjudged, pilot in command (cause)
  - porpoise/pilot-induced oscillation - initiated, pilot in command (cause)
  - recovery from bounced landing - not attained, pilot in command (cause)
  - lack of total experience in type operation, pilot in command (contributing factor)
- Nose over, landing - roll
  - landing gear,nose gear - overload

## Analysis

THE STUDENT PILOT WAS PERFORMING HIS FIRST SOLO FLIGHT AND LANDING. HE MISJUDGED THE AIRPLANE'S ALTITUDE, LANDED HARD AND BOUNCED. THE STUDENT PILOT FAILED TO CORRECT THE BOUNCED LANDING AND BEGAN TO PORPOISE UNTIL THE AIRPLANE'S NOSE LANDING GEAR COLLAPSED.
