While cruising at FL350 the crew heard a bang and noted the loss of no 3 engine power. A safe emergency landing was carried out at Tampa International Airport, FL (TPA). It appeared that the forward lavatory external seal was missing the safety button and the internal seal was improperly installed allowing for leakage when the airplane was pressurized. Frozen chunks of lavatory fluid had been ingested by the no. 3 engine, causing it to separate from the fuselage.

PROBABLE CAUSE: "The failure of company service personnel to properly service the airplane forward lavatory."
