BA had a number of 747 flap failures in the '70s, but if it's the one I'm thinking of (G-AWNB on a training detail from Prestwick in May 1975) it was a foreflap which ended up in the sea, but not before hitting 4R so hard that the door was forced inwards and debris from the door, chute, etc was scattered through the rear cabin (which was of course, happily, unoccupied).
