Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

Procedures/directives were not followed. Factors to the accident were: improper fuel boost pump selector position, leaded spark plugs and sunglare.

Analysis

While in the pattern for landing, the engine experienced a loss of power. The pilot was unable to land on the runway and a forced landing was initiated to an open school yard. During the emergency descent, the airplane collided with power lines and struck the ground in a nose down attitude, vertical to the terrain. During the on scene investigation, it was found that the spark plugs were coated with a layer of black carbon. Cockpit inspection revealed that the auxiliary fuel pump switch was positioned in the low setting. There were no mechanical failures or malfunctions noted.
