FT. SCOTT, KS, USA
N87LF
FLAGG STAR LITE
THE PILOT HAD PLANNED TO MAKE SEVERAL PASSES OVER HIS PARENTS' HOUSE. ON THE THIRD PASS WITNESSES OBSERVED A WING DEPART THE AIRCRAFT AND THE AIRCRAFT FELL FROM THE SKY. THE AIRCRAFT CAME TO REST IN A RIVER. EXAM OF THE AIRCRAFT COMPONENTS REVEALED A SPAR AND SPAR ATTACHMENT FAILURE. COMPARISON OF THE MANUFACTURING PROCESS DISCLOSED AN IMPROPERLY CONSTRUCTED MAIN SPAR (WHERE THE SPARS ATTACH TO EACH OTHER AND TO THE FUSELAGE). A REVIEW OF THE PILOT'S LOG BOOKS DID NOT SHOW ANY LOGGED TIME IN THIS AIRCRAFT.
THE FAILURE OF THE MAIN SPARS AT THE ATTACHMENT POINTS INSIDE THE FUSELAGE.
