Airworthiness Directive · Amendment 39-22457 · Fuselage
The Boeing Company Airplanes
This AD applies to all The Boeing Company Model 747-8 and 747-8F series airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 747-8 and 747-8F series airplanes. This AD was prompted by reports of cracks in stringers, common to the end fittings, forward and aft of the pressure bulkhead at station (STA) 2360 at multiple stringer locations. This AD requires repetitive inspections of stringer sidewalls and certain stringer assemblies, common to the end fittings, forward and aft of the pressure bulkhead at STA 2360 for any crack, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified by paragraph (h) of this AD: At the applicable times specified in the “Compliance” paragraph of Boeing Alert Requirements Bulletin 747-53A2910 RB, dated September 21, 2022, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 747-53A2910 RB, dated September 21, 2022.
Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin 747-53A2910, dated September 21, 2022, which is referred to in Boeing Alert Requirements Bulletin 747-53A2910 RB, dated September 21, 2022.
(1) Where the Compliance Time columns of the tables in the “Compliance” paragraph of Boeing Alert Requirements Bulletin 747-53A2910 RB, dated September 21, 2022, use the phrase “the original issue date of Requirements Bulletin 747-53A2910 RB,” this AD requires using “the effective date of this AD.”
(2) Where Boeing Alert Requirements Bulletin 747-53A2910 RB, dated September 21, 2022, specifies contacting Boeing for repair instructions: This AD requires doing the repair using a method approved in accordance with the procedures specified in paragraph (i) of this AD.
