## Discrepancy

ON APPROACH HAD LT MAIN GEAR UNSAFE WARNING, ALSO HAD A STRANGE VIBRATION NOT NORMALLY FELT WITH THE GEAR DOWN. DECLARED AN EMERGENCY AND LANDED WITH UNSAFE GEAR.  LEFT MAIN LANDING GEAR WARNING ACTIVATES ON LH PROXIMITY SENSOR (15GA).  SENSOR TARGET FOUND LOOSE.  WHEN SHAKEN LEFT MAIN LANDING GEAR DOOR WOULD DROP A LITTLE AND WARNING WOULD ACTIVATE, THEN CLOSE AND SHOW NORMAL INDICATION.
