## Probable cause

THE FAILURE OF AIRPORT PERSONNEL TO PERFORM THE NECESSARY RUNWAY MAINTENANCE.  CONTRIBUTING TO THIS ACCIDENT WAS THE DARK NIGHT AND HIGH VEGETATION.

## Sequence of events

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

- In flight collision with terrain/water, landing - flare/touchdown
  - terrain condition - high vegetation (contributing factor)
  - other airport/runway maintenance - not performed, airport personnel (cause)
  - light condition - bright night (contributing factor)

## Analysis

THE PILOT WAS COMPLETING A NIGHT AERIAL APPLICATION FLIGHT ON A PRIVATELY OWNED 2700 FT LONG BY 25 FT WIDE AIRSTRIP. DURING THE LANDING FLARE THE RIGHT WING BOOM BECAME ENTANGLED WITH THE HIGH VEGETATION THAT AIRPORT PERSONNEL FAILED TO MAINTAIN.  HIGH VEGETATION AND A DIRT BANK PARALLELS THE RUNWAY'S EDGE.  THE PILOT APPLIED FULL POWER TO GO-AROUND, BUT TO NO AVAIL.  THE AIRPLANE'S RIGHT WING STRUCK THE DIRT BANK AND SPUN THE AIRPLANE.  THE AIRPLANE'S WING SPAN IS 44 FT, 5 INCHES.
