Mentha, MI, US

On July 31, 1998, an Air Tractor AT-301 (registration N3659T) was involved in an aviation accident near Mentha, MI. Investigators recorded the probable cause as: The pilot's failure to maintain directional control during the landing roll on an uneven surface covered with loose gravel, which resulted in the aircraft veering off the road and into a ditch. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An aerial applicator aircraft landed on an uneven gravel road, struck roadside vegetation, and veered off course into a ditch following touchdown.

What happened

The pilot of an aerial applicator airplane executed a landing on a roadway characterized by an uneven surface and loose gravel. Mature corn fields bordered the edges of this road. Upon initial contact with the ground, the left wing tip of the aircraft struck the adjacent corn stalks. Subsequent tracks in the gravel indicated that the airplane yawed approximately 45 degrees to the left shortly after touchdown. The vehicle continued its trajectory through a ditch and into the cornfield, where it finally came to rest.

The investigation

Examination of the accident site revealed distinct furrows in the gravel surface. These tracks provided evidence of the aircraft's directional change immediately following impact with the ground. The path of the debris and tire marks extended from the road surface, through a roadside ditch, and into the vegetation where the airplane stopped.

Findings

The uneven terrain and loose gravel on the landing surface likely contributed to the loss of directional control. The presence of mature corn along the road edges presented an obstacle that was struck during the initial phase of the landing roll. The subsequent yaw to the left directed the aircraft off the roadway and into a ditch.

Safety message

Pilots operating aerial applicator aircraft should exercise extreme caution when selecting emergency or unprepared landing sites. Roads with uneven surfaces, loose gravel, or nearby vegetation pose significant risks for loss of control upon touchdown.

Probable cause

The pilot's failure to maintain directional control during the landing roll on an uneven surface covered with loose gravel, which resulted in the aircraft veering off the road and into a ditch.
