1989-06-10: Cessna 170B (N3100B) — Carlton, Thomas M. — Sarasota, FL

Sarasota, FL, US

On June 10, 1989, a Cessna 170B (registration N3100B) operated by Carlton, Thomas M. was involved in an aviation accident near Sarasota, FL. Investigators recorded the probable cause as: The pilot's failure to maintain adequate airspeed during a turn, which resulted in an aerodynamic stall and spin, due to distraction while looking for cattle. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot lost airspeed while maneuvering to spot cattle, causing the aircraft to stall, enter a spin, and crash into trees.

What happened

The accident occurred while the pilot was engaged in agricultural operations, specifically maneuvering to locate cattle for a ground crew. During this phase of flight, the pilot executed a turn intended to reverse direction. As the aircraft turned, the pilot's attention shifted away from flight instruments and external references to visually search for livestock. This distraction led to a failure to maintain adequate airspeed.

As the airspeed decreased below the critical threshold, the airplane entered an aerodynamic stall. The loss of lift resulted in the aircraft entering a spin. Control was not regained before impact, and the aircraft crashed into trees and the ground.

The investigation

The investigation focused on the flight dynamics leading to the crash. Evidence indicated that the primary factor was the reduction of airspeed during the turn. The sequence of events showed a direct correlation between the pilot's visual distraction and the subsequent loss of control.

Findings

The critical finding was that the stall was caused by the pilot allowing airspeed to decay while distracted by ground operations. The failure to monitor airspeed during a low-altitude maneuver resulted in the spin and subsequent collision with terrain.

Probable cause

The pilot's failure to maintain adequate airspeed during a turn, which resulted in an aerodynamic stall and spin, due to distraction while looking for cattle.
