ON FINAL APPROACH, THE LANDING GEAR WAS EXTENDED, CHECKED DOWN AND LOCKED, AND THREE GREEN LIGHTS WERE NOTED. THIS WAS CORROBORATED BY THE COCKPIT VOICE RECORDER. WHEN THE AIRPLANE TOUCHED DOWN, THE LEFT MAIN LANDING GEAR EITHER COLLAPSED OR RETRACTED. THE LANDING GEAR ACTUATOR RODS, ROD ENDS, DOWN LOCK ROLLERS, AND CAMS WERE UNDAMAGED. DURING POST-INCIDENT EXAMINATION, THE HYDRAULIC POWER PACK MADE A LOUD NOISE AND HYDRAULIC PRESSURE FLUCTUATED BETWEEN 500 AND 1,200 PSI. NO DISCREPANCIES WERE NOTED WHEN THE HYDRAULIC POWER PACK WAS FUNCTIONALLY TESTED AND INTERNALLY INSPECTED. PROCEDURAL ERRORS WERE MADE THAT MIGHT HAVE INVALIDATED THE TEST RESULTS.
Probable Cause: THE PARTIAL FAILURE OF THE HYDRAULIC PUMP (POWER PACK).
