## Probable cause

THE STUDENT PILOT NOT FLARING FOR THE TOUCHDOWN.

## Sequence of events

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

- Nose gear collapsed, landing - flare/touchdown
  - flare - not performed, pilot in command (cause)
  - porpoise/pilot-induced oscillation - inadvertent, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)

## Analysis

DURING THE STUDENT PILOT'S THIRD SOLO LANDING HE FAILED TO FLARE FOR TOUCHDOWN. THE AIRCRAFT PORPOISED AND IMPACTED THE RUNWAY ON THE NOSE LANDING GEAR. THE IMPACT COLLAPSED THE NOSE GEAR.
