Aircraft Accident/Incident Report

Independence, Oregon 97351
Sunday, May 7, 2000 8:01 PDT

NTSB Narrative Summary Released at Completion of Accident

Approximately 100 feet above ground level the engine of the pilot/builder assembled RV-8 kit-plane began to run rough. The pilot made a left 90 degree turn to return to land during which all power was lost. He then turned back right and landed hard, collapsing the landing gear. Fueling records revealed approximately 10 gallons of fuel in the right tank per the pilot's estimate. Post-crash examination revealed that the fuel pick-up tube within the right tank had become mis-positioned (twisted) approximately 180 degrees, placing the tube pick-up end at the mid-level of the 21 gallon tank, and resulting in fuel starvation. The pilot had done maintenance on the right tank several weeks earlier including tightening a hex nut which retained the 90-degree elbow fitting holding the pick-up tube in place. Tightening of the hex nut without an anti-rotation bracket could rotate the pick-up tube into a mis-position. The aircraft design and construction predated the dissemination of design plans containing the anti-rotation bracket, and the manufacturer had not issued any notice of the bracket specifications to the pilot/builder. The pilot/builder, unaware of the specifications, had not installed the bracket in the right fuel tank.

NTSB Probable Cause Narrative

The rotation of the right fuel tank elbow fitting within the tank during previous maintenance. The improper alignment resulted in the fuel pick-up tube being mis-positioned and a subsequent starvation of fuel to the engine. Contributing factors were the non-installation of an anti-rotation bracket to secure the elbow fitting, the kit manufacturer's failure to issue a notice of the bracket design to previous aircraft owners, and the pilot's not establishing/maintaining a proper rate of descent resulting in a hard landing.
