Abstract
The FAA is correcting typographical errors in an existing airworthiness directive (AD) that was published previously in the Federal Register. The error resulted in two incorrect paragraph references. This AD applies to certain Boeing 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 requires repetitive detailed inspections of the aft pressure bulkhead for indications of "oil cans" and previous oil can repairs at reduced compliance times, and corrective actions if necessary.
