Narrative:
THE PILOT STATED THAT AFTER TOUCHDOWN ON THE RUNWAY, THE AIRCRAFT VEERED OFF THE RUNWAY TO THE LEFT. EXAMINATION OF THE LEFT MAIN LANDING GEAR REVEALED THAT THE GEAR STRUT WAS FRACTURED, AND THE LEFT LANDING GEAR HAD COLLAPSED. FURTHER EXAMINATION OF THE FRACTURE SURFACE REVEALED A RADIAL AREA ABOUT 3/8 TO 1/2 INCH IN SIZE, THAT WAS QUITE DIFFERENT FROM THE HOMOGENOUS, FINE, GRAY GRANULAR APPEARANCE OF THE REMAINDER OF THE FRACTURE. THE OUTER 1/32 INCH OF THE DIFFERENT APPEARING AREA WAS DISCOLORED BLACK, WHICH REVEALED THE PRESENCE OF A PREVIOUSLY UNDETECTED FRACTURE.

Probable Cause: The fatigue failure of the main landing gear strut that resulted in a loss of control.
