## Sequence of events

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

- In flight collision with object, maneuvering - aerial application
  - aircraft performance,climb capability - exceeded (cause)
  - object - tree(s) (contributing factor)
  - in-flight planning/decision - inaccurate, pilot in command (cause)
  - climb - misjudged, pilot in command (cause)
  - terrain condition - uphill
  - aircraft weight and balance - improper, pilot in command (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE ACFT COLLIDED WITH TREES DURING A PULL-UP AT THE END OF A SWATH RUN. DURING THE COLLISION THE RT WING TIP SEPARATED FROM THE ACFT AND THE ACFT ROLLED HITTING THE GROUND WITH THE RT WING FIRST WHICH STARTED A CARTWHEEL. INVESTIGATION REVEALED THAT THE ACFT WAS 216 LBS OVER GROSS WEIGHT AT THE TIME OF THE ACCIDENT. THE PLT SAID HE INCORRECTLY JUDGED THE ROLLING TERRAIN WHICH HE FOUND HE COULD NOT OUTCLIMB.
