1988-08-31: Cessna 170B (N2905D) — Fick, John — Willow, AK

Willow, AK, US

On August 31, 1988, a Cessna 170B (registration N2905D) operated by Fick, John was involved in an aviation accident near Willow, AK. Investigators recorded the probable cause as: The student pilot's improper reaction to turbulence, which resulted in an aerodynamic stall during the initial climb. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A student pilot stalled the aircraft during initial climb after a touch-and-go, striking trees at the runway end due to rapid control input following turbulence.

What happened

The accident occurred during a training flight involving a touch-and-go maneuver. After the student pilot executed the touchdown and initiated the takeoff roll, the aircraft entered the initial climb phase. During this ascent, the airplane encountered turbulence. The student pilot reportedly became startled by the turbulent conditions and reacted by pulling back rapidly on the control yoke. This abrupt input caused the aircraft to exceed its critical angle of attack, resulting in an aerodynamic stall. Unable to recover from the stall, the aircraft descended and impacted a row of trees located at the end of the runway.

The investigation

Post-accident analysis included interviews with both the student pilot and the pilot-in-command, who was also the certified flight instructor (CFI) on board. The CFI stated that he was unable to react quickly enough to correct the aircraft's attitude once the stall had been initiated by the student's input. No mechanical failures or malfunctions were identified as contributing factors.

Findings

The primary factor in this accident was the student pilot's improper reaction to turbulence, which led to a loss of control due to an aerodynamic stall. The rapid back-pressure on the controls exceeded the aircraft's lift capabilities at that airspeed and configuration. The CFI's inability to intervene in time further contributed to the outcome.
