Registration: N653LA
Aircraft: Air Tractor AT 602
Aircraft Damage: Substantial
Defining Event: Collision during takeoff/land
Injuries: 1 None
Flight Conducted Under: Part 137: Agricultural 


The pilot reported that the turf airstrip had a "sunken area," which created a "ramp." During takeoff, the airplane encountered this portion of the airstrip and became "airborne prematurely." The airplane subsequently settled into ground effect; however, the left wing impacted a small tree near the end of the runway, and the airplane then pitched "downward and left," and the airplane was unable to maintain altitude. The airplane impacted a field off the end of the runway. The airplane sustained substantial damage to the wings and fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The airplane's encounter with a sunken area during takeoff from a turf runway, which resulted in the airplane becoming prematurely airborne and impacting a tree and then terrain.

  1. All the mud-painted 4x4 trucks around there (a way of proudly showing the public you *really* use your 4x4 truck) are going to be jealous of this mud paint.
