1995-10-05: Grumman G-164A (N9873) — Hamburg, AR

Hamburg, AR, US

On October 5, 1995, a Grumman G-164A (registration N9873) was involved in an aviation accident near Hamburg, AR. Investigators recorded the probable cause as: The failure of an engine cylinder, which caused a loss of engine power during the initial climb. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A light aircraft experienced an engine surge and power loss at approximately 175 feet above ground level during the initial climb phase of flight, prompting an emergency landing attempt in adjacent agricultural terrain.

What happened

The pilot was conducting a routine flight when the aircraft encountered a critical mechanical failure shortly after departure. During the initial takeoff climb, at an altitude of approximately 175 feet above ground level (AGL), the engine suddenly surged and subsequently lost power. With forward momentum limited and altitude low, the pilot initiated an emergency landing procedure.

The pilot directed the aircraft toward a nearby bean field, attempting to execute a controlled touchdown on the relatively flat agricultural surface. Although the initial contact with the field was achieved, the aircraft failed to remain within the cultivated area. Shortly after touching down, the airplane exited the bean field and collided with a ditch. This secondary impact resulted in damage to the airframe.

The investigation

Following the accident, the pilot provided a detailed account of the mechanical failure that precipitated the emergency landing. Investigation into the engine components revealed that an engine cylinder had failed prior to or during the power loss event. This internal component failure was identified as the primary reason for the sudden surge and subsequent loss of propulsion.

Findings

The sequence of events indicates that the aircraft was unable to maintain flight due to a mechanical anomaly in the powerplant. The pilot's decision to land in the bean field was a direct response to the immediate loss of thrust at a low altitude. The damage sustained was a result of the aircraft departing the intended landing zone and striking terrain features, specifically the ditch, after the initial touchdown.

Probable cause

The failure of an engine cylinder, which caused a loss of engine power during the initial climb.
