What happened
The pilot was operating an airplane during a night aerial application mission. After completing a standard swath run, the pilot initiated a low-level turn. During this maneuver, the pilot identified high tension wires in the flight path and executed a tight turn to avoid them. The aircraft failed to maintain sufficient altitude during this correction, resulting in the left wing striking the ground. The impact caused substantial damage to the airframe, which was subsequently destroyed by a post-impact fire.
The investigation
Examination of the wreckage revealed that the left wing had impacted the terrain with significant force. The structural failure was consistent with a collision with the ground rather than mechanical failure or loss of control prior to impact. The fire that followed the initial contact consumed the majority of the airframe, but no evidence of pre-impact engine malfunction was found.
Findings
The primary factor in this accident was the pilot's inability to maintain adequate altitude during a low-level maneuver in night conditions. The decision to execute a tight turn at low altitude to avoid obstacles left insufficient margin for error. The high tension wires were likely difficult to discern against the dark background, contributing to the late detection and subsequent aggressive avoidance maneuver.
Safety message
Pilots conducting low-level operations at night must maintain heightened situational awareness regarding terrain and obstructions. Adequate altitude should be preserved during turns to allow for error correction, especially when visibility is reduced.
