ACCORDING TO THE PILOT, HE HAD THE BRAKES REPAIRED AT EL PASO, TEXAS, AND WAS DISTRACTED BY WORRY OVER THE BRAKES ABILITY TO STOP ON THE DOWN HILL RUNWAY. HE REPORTED THAT HE MADE A NORMAL APPROACH TO RUNWAY 27, AND FLARED HIGH BECAUSE OF THE DARKNESS, RESULTING IN A HARD LANDING. THE PLANE BOUNCED BACK INTO THE AIR, THE PILOT ADDED POWER AND MADE A GO-AROUND. HE SAID THE ENGINE VIBRATED BADLY, AND HE ASSUMED THE PROPELLER STRUCK THE RUNWAY, EITHER DURING THE HARD LANDING OR AS HE ADDED POWER. ON THE SECOND APPROACH, AT TOUCHDOWN, THE NOSE GEAR COLLAPSED, THE PLANE DEPARTED THE RUNWAY, SHEARED THE MAIN GEAR AND CAME TO REST NOSE DOWN. THE RIGHT WING WAS BENT BACK, BOTH WING SPARS, THE FUSELAGE AND TAIL SECTION WERE DAMAGED. THE INVESTIGATION REVEALED THE MAIN LANDING GEAR LEGS WERE OVER STRESSED AND THE LOWER FUSELAGE WAS CRUSHED INWARD.
