## Probable cause

THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL.

## Sequence of events

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

- Main gear collapsed, landing - roll
  - directional control - not maintained, pilot in command (cause)

## Analysis

AT OR SHORTLY AFTER TOUCHDOWN THE RECENTLY CERTIFICATED PRIVATE PILOT ALLOWED THE AIRCRAFT TO ENTER A LEFT SKID AS EVIDENCED BY SKID MARKS DEPOSITED ON THE RUNWAY BY ALL THREE TIRES.  THE SKID MARKS THEN INDICATE A REVERSAL FROM LEFT TO RIGHT DURING WHICH THE RIGHT MAIN LANDING GEAR COLLAPSED.  WINDS WERE CALM AND NO MECHANICAL MALFUNCTION OF AIRCRAFT SYSTEMS WAS FOUND.
