## Sequence of events

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

- Undershoot, approach - vfr pattern - final approach
  - planned approach - inaccurate, pilot in command (cause)
  - visual/aural perception, pilot in command (cause)
  - distance - misjudged, pilot in command (cause)
  - clearance - not maintained, pilot in command (cause)
  - proper touchdown point - not attained, pilot in command (cause)

## Analysis

THE ACFT LANDED 3 FT SHORT OF THE RWY ON AN INCLINED CONCRETE SLOPE. THE WEATHER WAS VMC. AT THE APPROACH TO THE RWY A CONCRETE EMBANKMENT SLOPES DOWNWARD ABOUT 10 FT TO A ROAD. THE ACFT HIT ON THIS EMBANKMENT BOUNCED AND SLID 75 FT DOWN THE RWY. DISCUSSIONS WITH THE ARPT MGR REVEALED THAT THE APPROACH IS VISUALLY DECEPTIVE DUE TO THE RISING CONCRETE WHICHIS THE SAME COLOR AS THE RWY. NEITHER THE PILOT OR OPERATOR FILED AN ACCIDENT REPORT.
