A pilot spraying a field struck the ground during a landing attempt after flying over power lines. The belly tank separated and the aircraft sustained structural damage, but the pilot continued flying and landed safely.

Incident Overview

A pilot engaged in agricultural spraying operations reported an accident while working a field bordered by two power lines on the north edge. The pilot had been making passes under the wires but encountered a section where two poles were too close together, prompting a decision to fly over the wires instead.

Maneuver and Impact

After executing a procedure turn back toward the field, the pilot reduced power while crossing over the wires and began a descent. Power was reapplied, but the pilot stated the action was too late. The aircraft subsequently struck the ground in a three-point attitude. During the impact, the belly tank separated from the aircraft, folded under the aft section, and damaged two longerons forward of the tail section.

Post-Impact Flight

Despite the damage, the pilot retained control and continued flying. The aircraft was landed without further incident. An examination revealed that the tips of both propeller blades were chipped.

Damage Assessment

The aircraft sustained damage to the belly tank, which separated and caused structural damage to the aft section including two longerons. The propeller blades also exhibited chipping at the tips.

Operational Context

The pilot was conducting a spraying operation in an agricultural field. The presence of power lines at the edge of the field necessitated careful maneuvering. The decision to fly over the wires after encountering closely spaced poles led to a descent that resulted in ground contact.
