Aircraft Overruns Runway and Strikes Gravel Pile (N3496R)

Lodi, CA, US

On June 14, 1986, a Cessna 182L (registration N3496R) operated by Troy W. Johnson was involved in an aviation accident near Lodi, CA. Investigators recorded the probable cause as: The pilot's decision to land on Runway 12 in variable wind conditions resulted in a runway overrun, during which the aircraft collided with a gravel pile located on the grass overrun area. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An aircraft overran the end of a 2,070-foot asphalt runway during landing in variable wind conditions and collided with a gravel pile situated on the grass overrun area.

What happened

The aircraft was operating at an airport featuring a 2,070-foot asphalt runway. During the approach phase, the pilot observed that the windsock at the airfield was indicating a variable wind direction ranging from 200 degrees to 230 degrees. Despite these conditions, the pilot elected to land on Runway 12.

Upon touchdown, the aircraft failed to stop within the confines of the paved surface and overran the end of the runway. The aircraft continued forward onto the grass area beyond the runway threshold. As it moved across this overrun zone, it collided with a pile of gravel that was situated directly in its path. The gravel pile measured approximately 20 inches in height and extended across the width of the grassy area where the aircraft came to rest.

The investigation

Post-accident examination revealed that the primary cause of the collision was the presence of the gravel pile on the designated overrun area. The pilot indicated that sufficient distance remained on the grass to bring the aircraft to a safe stop if the obstruction had not been present. No other mechanical failures or environmental factors were cited as contributing to the overrun itself, aside from the wind conditions noted during the approach.

Findings

The investigation determined that the collision with the gravel pile resulted directly from the runway overrun. The presence of the 20-inch high gravel pile across the grass overrun area prevented the aircraft from stopping safely after leaving the paved surface. The variable wind conditions reported by the pilot were noted but did not preclude a safe landing; however, they may have influenced the decision-making process regarding the approach and touchdown point.

Safety message

This incident highlights the critical importance of maintaining clear overrun areas at airports. Obstructions such as gravel piles in grassy zones beyond runway ends can prevent aircraft from stopping safely after an overrun, leading to avoidable damage. Airport operators should ensure that overrun areas are kept free of debris and obstacles to provide adequate safety margins for landing aircraft.

Probable cause

The pilot's decision to land on Runway 12 in variable wind conditions resulted in a runway overrun, during which the aircraft collided with a gravel pile located on the grass overrun area.
