## Sequence of events

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

- Loss of control - in flight, takeoff - initial climb
  - aircraft performance,climb capability - exceeded (contributing factor)
  - stall/mush - inadvertent, pilot in command (contributing factor)
  - weather condition - high density altitude (contributing factor)
  - performance data - misjudged, pilot in command (cause)
- In flight collision with terrain/water, takeoff - initial climb
  - terrain condition - ground (contributing factor)
  - load jettison - delayed, pilot in command (cause)

## Analysis

ON TAKEOFF FOR AN AERIAL APPLICATION FLIGHT AT MAXIMUM GROSS WEIGHT THE AIRCRAFT BEGAN TO SETTLE. THE AIRCRAFT IMPACTED THE GROUND IN A SLIGHTLY NOSE-DOWN ATTITUDE. INVESTIGATION REVEALED THE ACCIDENT SITE ELEVATION WAS 5300 FEET MSL AND THE TAKEOFF WAS MADE TO THE EAST WITH WINDS FROM 270 DEGREES AT 14 KNOTS.
