General Maintenance Action
Procedure
Climbing out; Flight Attendant called at approximately 3;000 feet and reported a metallic sound hit the aircraft on takeoff and climbout. The takeoff itself was uneventful from the flight deck and no threat posed by the attitude at rotation; etc. However; we departed behind a heavy aircraft and once airborne experienced a lateral shifting of the aircraft in wake vortices; which may have shifted cargo. Flight control and flight response were normal throughout the flight as was systems integrity. I mentioned the Flight Attendant report to Departure Control; so that they might warn the Tower for a possible FOD inspection of the runway. Once at destination; a walk around was performed and there were no issues with the aircraft; no damage whatsoever.
B777 Captain reported encountering wake turbulence behind a Heavy aircraft during departure from IAH airport.
