Aircraft Collides With Tree and Levee During Takeoff (N6642K)

Kinder, LA, US

On June 4, 1983, a Grumman G-164B (registration N6642K) was involved in an aviation accident near Kinder, LA. Investigators recorded the probable cause as: The pilot's failure to adequately check wind conditions prior to takeoff, which resulted in a stall during rotation and subsequent collision with terrain obstacles. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

During takeoff, the aircraft stalled after a wind shift, striking a tree and a levee before nosing over. The pilot attributed the incident to insufficient wind checks.

What happened

The aircraft collided with a tree and a levee during the initial climb phase of flight. According to the pilot, the wind direction shifted either just before or during the takeoff roll. At the moment of rotation, the aircraft felt as though it had stalled. Consequently, the aircraft failed to clear a small tree located near the departure path. The impact forced the aircraft into an adjacent levee, where it nosed over upon impact.

The investigation

Post-accident examination focused on the mechanical condition and flight parameters. No mechanical failures were reported that would have contributed to the stall characteristics. The primary focus remained on the environmental conditions and pilot decision-making during the critical takeoff phase.

Findings

The pilot acknowledged that a more thorough check of the wind conditions prior to takeoff might have prevented the incident. The shift in wind direction likely resulted in an unexpected loss of airspeed or lift at rotation. This environmental factor, combined with the failure to clear the obstacle, led to the collision.

Safety message

Pilots should ensure comprehensive wind checks are performed immediately before takeoff. Sudden wind shifts can significantly affect aircraft performance and obstacle clearance capabilities during the critical initial climb.

Probable cause

The pilot's failure to adequately check wind conditions prior to takeoff, which resulted in a stall during rotation and subsequent collision with terrain obstacles.
