ACTION: Final rule.
AGENCY:
The FAA is adopting a new
airworthiness directive (AD) for all The
Boeing Company Model 777–200,
–200LR, –300, –300ER, and 777F series
airplanes. This AD was prompted by a
report of a 5-inch crack on the upper
wing skin at a certain wing station of the
right wing. This AD requires repetitive
inspections for cracking of the upper
wing skin common to certain fasteners
and applicable on-condition actions.
The FAA is issuing this AD to address
the unsafe condition on these products.
DATES: This AD is effective April 23,
2025.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of April 23, 2025.
ADDRESSES:
AD Docket: You may examine the AD
docket at regulations.gov under Docket
No. FAA–2023–2151; or in person at
Docket Operations between 9 a.m. and
5 p.m., Monday through Friday, except
Federal holidays. The AD docket

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all The Boeing Company Model
777–200, –200LR, –300, –300ER, and
777F series airplanes. The NPRM
published in the Federal Register on
November 17, 2023 (88 FR 80216). The
NPRM was prompted by a report of a 5inch crack on the upper wing skin at
wing station (WSTA) 460 of the right
wing. In the NPRM, the FAA proposed
to require repetitive inspections for
cracking of the upper wing skin
common to certain fasteners and
applicable on-condition actions,
including repair.
The FAA issued a supplemental
notice of proposed rulemaking (SNPRM)
to amend 14 CFR part 39 by adding an
AD that would apply to all The Boeing
Company Model 777–200, –200LR,
–300, –300ER, and 777F series
airplanes. The SNPRM published in the
Federal Register on September 20, 2024
(89 FR 77049). The SNPRM was
prompted by reports from Boeing of two
events of cracking at the fastener 6 and
7 locations where the cracks initiated in
the spanwise (inboard/outboard)
direction. These cracks were detected
only because of a repair accomplished
on an adjacent fastener. The areas
around the repaired fasteners were
subsequently inspected with an open
hole high frequency eddy current
(HFEC) inspection, rather than with the
ultrasonic (UT) inspection that was
proposed in the NPRM. The SNPRM
therefore proposed to require open hole
HFEC inspections instead of UT
inspections. The FAA is issuing this AD
to address the possibility of an
undetected upper wing skin crack.
