## Probable cause

THE PILOT'S FAILURE TO ATTAIN THE PROPER TOUCHDOWN POINT.

## Sequence of events

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

- Undershoot, landing - flare/touchdown
  - proper touchdown point - not attained, pilot in command (cause)
- Main gear collapsed, landing - roll

## Analysis

THE AIRPLANE TOUCHED DOWN SHORT OF THE RUNWAY, AND SKIDDED ACROSS A RAISED LIP ONTO THE RUNWAY. THE PLANE THEN SKIDDED OFF THE RUNWAY TO THE LEFT. AFTER CROSSING AN OPEN AREA OF SAND, THE PLANE CAME TO REST ON A PARALLEL TAXIWAY. ALL LANDING GEAR, THE WINGS AND ELEVATOR WERE BENT. THE PILOT STATED THAT UPON TOUCHDOWN THE LANDING GEAR COLLAPSED.
