Factual narrative

THE HOMEBUILT, HIWING ACFT HAD JUST BEEN ASSEMBLED BY THE OWNER/PLT & WAS READIED FOR ITS 1ST FLT. AFTER TAKEOFF FROM RWY 25, THE ACFT ENTERED A CLIMB, TURNED BACK OVER THE ARPT & CROSSED OVER THE RWY. SUBSEQUENTLY, IT WAS MANEUVEREDABOUT 500 TO 800 FT SOUTH OF THE RWY, IN THE VICINITY OF A LEFT BASE TURN TO RWY 25. WHILE IN A LEFT TURN, THE BANK ANGLE INCREASED TO ABOUT 60 DEG & THE ACFT DESCENDED TO THE GROUND & CRASHED. IT STRUCK THE GROUND 486 FT SHORT OF RWY 25 ON A HDG OF 270 DEG. THE PLT WAS SERIOUSLY INJURED & COULD NOT REMEMBER DETAILS OF THE ACDNT. HE STATED HE COULD NOT GET FULL POWER FROM THE ENG. HOWEVER, NO SPECIFIC PROBLEMS WERE FOUND DURING AN EXAM OF THE ENG, EXCEPT THAT DEPOSITS IN THE FRONT CYLINDER WERE INDICATIVE OF A SLIGHTLY RICH FUEL MIXTURE.
