Airworthiness Directive 2026-13474
one-timeAirworthiness Directives; The Boeing Company Airplanes
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-8F series airplanes. This AD was prompted by reports of cracking in stringers and splice fittings located at stringer splices at multiple body stations. This AD requires an inspection of each free flange of the stringers at the stringer splice for radius fillers at certain fastener locations, an inspection for cracking of the stringers and stringer splice fittings at certain stringer splice locations, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2026-13474 applies to
Applies only to airplanes identified as Group 3 in Boeing Alert Requirements Bulletin 747-53A2907 RB, Revision 1, dated March 14, 2025.
Whether AD 2026-13474 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
