A Delta Airlines Boeing 767-300, registration N181DN performing flight DL-211 from Prague (Czech Republic) to New York JFK,NY (USA) with 133 people on board, was enroute about 240nm southsoutheast of the Southern Tip of Greenland, when the flight crew was informed about a flooding issue in the mid cabin lavatories shortly followed by flooding in the forward left lavatory. Some time after the flooding was discovered, the autopilot disconnected, the flight crew attempted to engage any of the three autopilots, however, none would remain connected. The aircraft began to drift to the right, and correction to the left was not possible. The flight crew contacted dispatch and maintenance reporting jammed flight controls and worked the related checklist. The crew declared emergency, descended the aircraft and coordinated with ATC for a diversion to Gander,NL (Canada). About 100nm east of Gander the flight controls returned to normal function. The crew terminated the emergency and set course to divert to Boston, MA (USA), subsequently while at FL110 determined that the fuel would be sufficient to continue to JFK. The aircraft landed on JFK's runway 04R about
4:15 hours after the onset of flooding.

The Canadian TSB reported maintenance replaced both grey water drain masts and a seal in the left wheel well canted pressure deck above the aileron feel centering and trim mechanism. The entire roll control and autopilot systems were inspected and repairs effected as needed.
