## Probable cause

The airport operator's failure to properly mark the runway construction project, the exposed lip at the runway end, and the pilot's failure to obtain NOTAM information prior to the flight.  A factor was the inadequate marking of the runway.

## Sequence of events

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

- On ground/water encounter with terrain/water, landing - roll
  - airport facilities,runway/landing area condition - exposed runway lip/edge (cause)
  - airport operations - inadequate, airport personnel (cause)
  - airport facilities,runway marking - inadequate (contributing factor)
  - preflight planning/preparation - inadequate, pilot in command (cause)

## Analysis

The airplane was damaged when it landed on the un-paved portion of a runway under construction and struck the end of the existing runway.  All three landing gear were separated from the airplane.  In a written statement, the pilot stated that he landed on the un-finished portion of a runway extension that was approximately 8 inches lower than the existing runway.  He stated that there were no markings visible from the air to indicate that the extension was not useable.  Plywood chevrons were placed in the grass adjacent to the sides of the runway extension.  There were no markings on the new runway extension.  The runway extension project was listed in a notice to airmen (NOTAM).
