Aircraft Collides with Hillside During Landing on Wet Runway (N756DM)

South Fox Isl., MI, US

On October 16, 1983, a Cessna U206G (registration N756DM) was involved in an aviation accident near South Fox Isl., MI. Investigators recorded the probable cause as: The pilot's failure to maintain directional control during landing on a wet, turf runway with a dogleg, resulting in a collision with terrain. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An aircraft slid sideways on a wet, turf runway with a dogleg and collided with a hillside mound during landing, damaging the wing, nose gear, and propeller.

What happened

The aircraft was operating on a 3,500-foot turf runway that features a significant 20-degree dogleg located approximately 1,500 feet from the north end. The airfield is characterized by small hills running along both sides of the strip. During the landing phase, the grass runway surface was wet, which compromised traction. As a result, the aircraft slid sideways off its intended path. It subsequently collided with a mound alongside the runway. The impact caused damage to the left wing, the nose gear, and the propeller.

The investigation

Examination of the site revealed that the wet runway conditions were a primary factor in the loss of directional control. The terrain adjacent to the airfield, specifically the hillocks running along the sides, presented an immediate hazard once the aircraft departed the paved surface. The physical damage sustained by the left wing, nose gear, and propeller is consistent with a lateral slide into elevated ground features.

Findings

The sequence of events indicates that the combination of wet runway conditions and the specific geometry of the airfield contributed to the accident. The dogleg in the runway alignment may have complicated landing procedures, but the immediate cause was the loss of traction on the turf surface. The aircraft's inability to maintain lateral position led directly to the collision with the hillock beside the runway. No injuries were reported among those on board.

Probable cause

The pilot's failure to maintain directional control during landing on a wet, turf runway with a dogleg, resulting in a collision with terrain.
