## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400F series airplanes. This AD was prompted by the determination that more restrictive tasks and limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate more restrictive tasks and limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
