To be sure, in ag operations the vast majority of pilots fly
"cocked and locked" for an immediate response to an emergency
or malfunction.


And then, there are those who aren't able to reach the four mile
distant work-site before winning a Darwin Award:

NTSB Identification: SEA97LA099 .
The docket is stored in the Docket Management System (DMS).
14 CFR Part 137: Agricultural
Accident occurred Monday, May 05, 1997 in ROSALIA, WA
Probable Cause Approval Date: 1/28/2000 1800 local time
Aircraft: Grumman G-164A, registration: N7926
Injuries: 1 Fatal.
The pilot-in-command departed the airport in a Grumman G-164A
spray plane. En route to the destination field, and while
overflying hilly terrain, the aircraft's tail wheel impacted the
ground, followed by the main gear. The aircraft continued over an
embankment, nosing over while crossing a paved road, before coming
to rest and burning. There was no evidence that the pilot
jettisoned the 2,040 pound herbicide load. Propeller slash marks
early in the ground track indicated high engine RPM at the initial
ground impact. Additionally, toxicological evaluation of samples
from the pilot-in-command revealed 0.002 ug/ml of
Tetrahydrocannabinol detected in blood, 0.08 ug/ml of
Tetrahydrocannabinol Carboxylic Acid detected in blood, and 0.035
ug/ml of Tetrahydrocannabinol Carboxylic Acid detected in urine
indicating fairly recent (within several hours) use of Marihuana.

The National Transportation Safety Board determines the probable
cause(s) of this accident as follows:

The pilot-in-command's failure to maintain clearance with terrain.
Factors contributing to the accident were, hilly terrain
conditions and impairment due to recent use of marihuana.
