## Analysis

DRG THE 2ND FLT OF THE NEWLY CONSTRUCTED HOME BUILT ACFT, THE ENG BEGAN TO LOSE POWER SHORTLY AFTER TAKEOFF. THE PLT REENTERED THE PATTERN FOR A PRECAUTIONARY LANDING, BUT MISJUDGED THE APCH & HAD TO GO AROUND. DRG THE NEXT APCH, THE ENG LOST POWER COMPLETELY. AN EMERG LNDG WAS MADE ON THE ARPT, BUT AT AN ANGLE TO THE RWYS. DRG THE LNDG, THE ACFT CONTACTED TERRAIN APRX 13 FT LEFT OF RWY 21, THEN SLID ACROSS RWY 21 & STOPPED BEFORE REACHING RWY 35. A POST ACDNT EXAM REVEALED THERE WAS FIBERGLASS IN THE FUEL LINE WHICH RESULTED IN FUEL STARVATION. THE ACFT HAD A FIBERGLASS FUEL TANK.
