1996-03-15: Cessna 140 (N76632) — Ulysses, KS

Ulysses, KS, US

On March 15, 1996, a Cessna 140 (registration N76632) was involved in an aviation accident near Ulysses, KS. Investigators recorded the probable cause as: The pilot's failure to maintain directional control during an aborted takeoff, which resulted in a nose-over, due to a lack of training on how to perform an aborted takeoff. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot aborted a takeoff after drifting right due to wind gusts, resulting in a nose-over. The pilot admitted lacking training for this specific maneuver.

What happened

The incident occurred during the initial phase of flight at a private airfield. As the aircraft accelerated down the runway for departure, the pilot experienced a sudden gust of wind that caused the airplane to drift laterally toward the right side of the paved surface. Recognizing the deviation from the intended centerline and the potential risk of leaving the runway, the pilot made the decision to abort the takeoff.

To stop the aircraft, the pilot applied a combination of braking pressure and forward elevator stick input. Despite these corrective actions, the aerodynamic forces and ground handling characteristics caused the nose of the aircraft to pitch down sharply. The airplane subsequently nosed over, coming to rest on its nose gear or fuselage rather than remaining on its main landing gear.

The investigation

Following the accident, investigators interviewed the pilot to understand the sequence of events and the decision-making process involved. The pilot provided a detailed account of the wind conditions and the lateral drift that prompted the abort. During the interview, the pilot disclosed a significant gap in their training history regarding this specific emergency procedure.

Findings

The primary factor contributing to the accident was the pilot's lack of formal instruction on how to properly execute an aborted takeoff. The pilot explicitly stated that they had never been taught the correct techniques for managing an aircraft during a rejected takeoff, particularly when dealing with crosswind components or sudden drift. This lack of training likely contributed to the improper use of control inputs, specifically the forward stick application, which exacerbated the nose-down pitching moment and led to the nose-over.

The investigation highlighted that while the decision to abort was reasonable given the drift, the execution was flawed due to insufficient procedural knowledge. The absence of specific training for high-energy rejected takeoffs left the pilot unprepared for the complex control inputs required to maintain directional control and prevent structural damage during such a critical phase of flight.

Probable cause

The pilot's failure to maintain directional control during an aborted takeoff, which resulted in a nose-over, due to a lack of training on how to perform an aborted takeoff.
