Delta 767 Flooding Lavatories Disrupt Autopilots

??A Delta Airlines Boeing 767-300, performing a flight from Prague to New York JFK, with 133 people on board, was enroute about 240Nm Southeast 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 (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.The entire roll control and autopilot systems were inspected and repairs effected as needed.
