Abstract
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes. This AD was prompted by reports of cracks of the upper splice fittings. This AD requires repetitive detailed inspections and open hole high frequency eddy current (HFEC) inspections of the upper splice fittings for cracks and applicable on- condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
