On July 22, 1988, an Air Tractor AT-301 (registration N8719S) was involved in an aviation accident near Niland, CA. Investigators recorded the probable cause as: The pilot's failure to maintain sufficient altitude during the initial climb after takeoff, which resulted in a collision with transmission wires and terrain. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
Shortly after takeoff, the pilot attempted to locate ground flaggers and avoid transmission wires by turning right and climbing. The aircraft failed to gain sufficient altitude, resulting in a collision with the wires and subsequent terrain impact.
What happened
The accident occurred shortly after the aircraft departed from the airport. Following takeoff, the pilot executed a right turn with two primary objectives: to locate ground flaggers operating on the surface and to avoid overhead transmission wires. Despite these efforts, the pilot was unable to visually identify the flaggers.
To continue avoiding the wires and rising terrain in the area, the pilot initiated a climb. However, the aircraft did not gain sufficient altitude to clear the obstacles. Consequently, the airplane collided with the transmission wires and subsequently impacted the terrain.
The investigation
An examination of the aircraft was conducted following the accident. The investigation revealed no reported mechanical failures or malfunctions of the airplane that would have contributed to the event. The aircraft systems appeared to be functioning normally prior to the collision.
Probable cause
The pilot's failure to maintain sufficient altitude during the initial climb after takeoff, which resulted in a collision with transmission wires and terrain.
