The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400 and 747-8 series airplanes.

This AD also requires an operation check of the stowage boxes or snubber, as applicable, and applicable on- condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
