2000-12-06: Air Tractor AT-502B (N50470) — South Florida Crop Care — Belle Glade, FL

Belle Glade, FL, US

On December 6, 2000, an Air Tractor AT-502B (registration N50470) operated by South Florida Crop Care was involved in an aviation accident near Belle Glade, FL. Investigators recorded the probable cause as: The pilot's failure to maintain adequate clearance from known wires during an agricultural operation, which resulted in damage to the aircraft and subsequent loss of control. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot conducting an agricultural swath run collided with overhead wires, resulting in immediate flight control issues and a subsequent loss of directional control upon landing at the departure airport.

What happened

The pilot was operating an aircraft for agricultural purposes when he initiated a flight path to the west. After completing this initial leg, the pilot executed a turn to head eastbound along the designated swath route. During this phase of the operation, the aircraft struck known overhead wires that were situated within the flight path.

The impact with the wires caused immediate and significant damage to the aircraft's systems. The pilot reported experiencing severe flight control problems directly following the collision. Despite the compromised state of the aircraft, the pilot managed to navigate back toward the departure airport.

Upon reaching the airport, the pilot attempted to land the damaged aircraft. While the initial touchdown was achieved, the aircraft suffered a loss of directional control during the landing roll out. The event concluded with the aircraft unable to maintain its intended path on the ground due to the mechanical failures incurred from the earlier in-flight collision.

The investigation

The examination of the incident focused on the sequence of events leading to the loss of control. Investigators noted that the pilot had encountered physical obstructions in the form of wires along the established agricultural route. The damage sustained during the in-flight collision was identified as the primary factor affecting the aircraft's operability.

The mechanical failure manifested as a lack of adequate flight control response immediately after the strike. This structural and system damage persisted through the return flight and directly contributed to the handling difficulties observed during the final phase of the operation. The loss of directional control on the ground was a direct consequence of the prior impact, which likely affected the landing gear or steering mechanisms.

Findings

The primary contributing factor to this accident was the collision with known wires during an agricultural operation. This event led to flight control problems that compromised the pilot's ability to manage the aircraft safely. The subsequent loss of directional control on landing roll out was a direct result of the damage sustained from the initial strike.

The incident highlights the risks associated with low-altitude flight operations near unmarked or known obstructions. The immediate degradation of flight controls following the wire strike left little margin for error during the return and landing phases. The pilot's decision to return to the departure airport was made under difficult mechanical conditions, which ultimately resulted in a controlled flight into terrain or obstacle scenario upon touchdown.

Probable cause

The pilot's failure to maintain adequate clearance from known wires during an agricultural operation, which resulted in damage to the aircraft and subsequent loss of control.
