What happened
The incident occurred while the pilot was conducting an agricultural spray run. During the final approach to the field, the pilot initiated a flare maneuver to reduce descent rate for landing. However, the main wheels of the aircraft made contact with the standing crop rather than the ground. The pilot attempted to apply full power and pull up to avoid impact, but was unable to gain sufficient altitude or control.
The landing gear became deeply entangled in the vegetation. This entanglement exerted a downward force on the airframe, pulling the aircraft directly into the ground. The collision resulted in significant structural damage to the aircraft. Additionally, an unknown quantity of the chemical permethrin leaked from the spray system into the field during the crash sequence.
The investigation
Post-accident examination revealed that the primary failure mode was mechanical entanglement rather than a system malfunction. The pilot reported that the landing gear caught in the crop, which prevented any further recovery attempts. No other mechanical failures were identified as contributing factors to the loss of control.
Findings
The accident sequence was driven by improper flare technique during the final phase of the approach. By flaring too high or at an incorrect airspeed, the pilot allowed the aircraft to descend into the crop canopy. The subsequent landing gear entanglement removed any possibility of a go-around, leading to a controlled flight into terrain.
Safety message
Pilots conducting agricultural operations must ensure that flare maneuvers are executed at the correct height and speed above the target surface. Flaring too high in low-level operations can result in vegetation entanglement with landing gear or propellers, which can rapidly lead to a catastrophic loss of control.
