Wind shear induced oscillations. Narita is infamous for its wind shear. Mountains too close on the inland side, sea too close on the other. We've repaired other structural damage caused by hard landings at that airport. We are, of course, not allowed to share. The only reason I can post this video is because someone else caught it and it's in the public domain.

Oh, and yes - we do actually "inflate" the airplane before we turn it over to the customer. We run what we call a "high blow" cycle on them wherein we pressurize the cabin to ensure that, well, it can actually do that after the repair. Nothing worse than a leaky airplane...
