## Discrepancy

CLIMBING THROUGH 20000FT ACCLERATING TOWARD 270KIAS THE LEFT GEAR DOWN LOCK LIGHT (GREEN) ILLUMINATED. THE AIRCRAFT WAS DECELERATED TO 200KIAS AND THE LIGHT WENT OUT AFTER ABOUT 2 MINUTES TOTAL ILLUMINATION. AT NO TIME DID THE RED GEAR UNLOCK LIGHT ILLUMINATE, HOWEVER A VERY SLIGHT AIRFRAME VIBRATION WAS DETECTED WHICH APPEARED TO VARY WITH SPEED BUT DISAPPEARED WHEN THE GREEN LIGHT WENT OUT..
