Narrative:

After taking off from runway 1 at geu; aircraft was departing geu class D airspace on right downwind to the south. At 800 ft AGL; airspeed approximately 80 mph; motor RPM 2750; there was the sound of an impact; and a fraction of a second later; aircraft began to vibrate violently. Engine was shut down by turning off magneto switch and vibration stopped. Geu remained within glide distance and aircraft landed uneventfully on runway 1 and came to rest on a taxiway to the left (west) of runway 1. Subsequent inspection of the aircraft revealed that 1 blade of the propeller was missing; motor mounts were damaged and loose; and there was cosmetic damage to lower cowl. No other damage to aircraft or other property and no personal injury. After vibration began radio failed to transmit and landing was made without authority/authorized from geu tower.
