## Discrepancy

DURING EXTENSION OF THE LANDING GEAR FOR LANDING, THERE WAS NO LEFT DOWN AND LOCKED INDICATION.  MANUAL HYDRAULIC EXTENSION WAS INEFFECTIVE.  PNEUMATIC EXTENSION SYSTEM WAS ACTIVATED WHICH LED TO A DOWN AND LOCKED INDICATION AND AN UNEVENTFUL LANDING WAS MADE.  DURING INSPECTION OF THE LEFT MAIN LANDING GEAR, THE MAIN LANDING GEAR EXTENSION ACTUATOR BOLT WAS FOUND MISSING.  A DETAILED INSPECTION FOUND THE BOLT HAD APPEARED TO HAVE SHEARED.
