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

- In flight collision with object, approach - vfr pattern - base leg/base to final
  - light condition - dusk (contributing factor)
  - visual lookout - inadequate, pilot in command (cause)
  - physical impairment(visual deficiency), pilot in command (cause)
  - object - tree(s) (contributing factor)
  - clearance - not maintained, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE ACFT COLLIDED WITH A TREE DURING THE APPROACH TO LAND. A WITNESS TO THE ACCIDENT, WHO HAD LANDED HIS ULTRALIGHT, SAID THE PLT CIRCLED TO LAND & THEN ABORTED TO MAKE ANOTHER APPROACH TO LAND CLOSER TO THE WITNESSS. AS HE MADE A RIGHT DESCENDING TURN TO ALIGN WITH THE RWY, THE ACFT COLLIDED WITH A TREE. THE ACFT THEN CRASHED TO THE GROUND IN A NOSE DOWN INVERTED ATTITUDE ABOUT 50 FT FROM THE TREE. THE LANDING AREA WAS AN UNLIGHTED TURF STRIP, 2700 FTLONG. THE STRIP WAS LOCATED IN A FENCED PASTURE. THE TREE WAS NEAR THE FENCE ON THE EAST SIDE OF THE 175 FT WIDE FIELD, ABOUT 600 FT FROM THE APPROACH END. THE PLT WAS NOT WEARING GLASSES AND HE SAID HIS EYESIGHT WAS POOR. THE AMOUNT OF DAYLIGHT LEFT AT THE TIME OF THE ACCIDENT MADE OBJECTS DIFFICULT TO SEE IN THE FADING TWILIGHT.
