Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Loss of engine power(partial) - mech failure/malfManeuvering - aerial application
Throttle/power lever,bellcrank - failure,partialCause
Forced landingDescent - emergency
Load jettison - performedPilot in commandFactor
Throttle/power control - inadvertent deactivationPilot in commandCause
In flight collision with terrain/waterLanding
Terrain condition - crop
Terrain condition - soft

Analysis

The acft began to lose power while engaged in aerial application so the plt dumped his load and headed for the airstrip. Enroute the power deteriorated so the plt elected to land. Cutting the mixture gave the engine a surge which caused an overshoot into standing corn. The cause of the power loss was found to be a failed throttle bolt.
