Aircraft Collides with House During Forced Landing Due to Fuel Exhaustion (N4UD)

Zachery, LA, US

On July 7, 1986, a Cessna P-210N (registration N4UD) was involved in an aviation accident near Zachery, LA. Investigators recorded the probable cause as: The pilot's failure to maintain adequate fuel supply, which resulted in total engine power loss. Contributing factors included loose fuel lines on cylinders #4 and #6. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

The pilot lost all engine power during cruise flight due to fuel exhaustion. Despite approach control vectors to a nearby airport, the aircraft could not reach it and struck a house under construction.

What happened

During cruise flight, the pilot experienced a total loss of engine power caused by fuel exhaustion. Air traffic control at Approach Control vectored the aircraft toward a closer airport in an attempt to facilitate a safe landing. However, the aircraft was already beyond gliding distance from the intended destination. Consequently, the aircraft collided with a house that was currently under construction.

The investigation

A post-accident inspection of the airframe and engine components revealed no fuel remaining in either wing tank. Further examination identified mechanical irregularities within the engine assembly; specifically, the fuel lines associated with cylinders #4 and #6 were found to be loose.

Findings

The primary factor leading to this accident was fuel exhaustion during cruise flight. Contributing factors included the inability of the aircraft to glide to a suitable landing site after power loss and the discovery of loose fuel lines on cylinders #4 and #6, which may have contributed to the fuel system failure or indicated maintenance issues.

Safety message

Pilots must ensure adequate fuel reserves are maintained for all phases of flight. Regular pre-flight inspections should include verification that all fuel line connections are secure and intact to prevent in-flight power loss.

Probable cause

The pilot's failure to maintain adequate fuel supply, which resulted in total engine power loss. Contributing factors included loose fuel lines on cylinders #4 and #6.
