"American transport officials warned of a potential weak spot in Boeing 777s which could lead to the "loss of structural integrity of the aircraft" four months before the disappearance of Malaysia airlines Flight MH370.
The Federal Aviation Administration in Washington drew up an Airworthiness Directive in November. It was triggered by reports of cracking in the fuselage skin underneath a Boeing aircraft's satellite antennae."
This does not concern the aircraft used on the MH370 flight, which is a Boeing 777-200ER.
