THIS BULLETIN IS SENT TO THE OPERATORS OF RECORD OF THE AIRPLANES SHOWN IN PARAGRAPH
1.A., EFFECTIVITY. IF AN AIRPLANE HAS BEEN LEASED OR SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OPERATOR. IF APPLICABLE SPARES HAVE BEEN SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OWNER.
CONCURRENT REQUIREMENTS None.
BACKGROUND This service bulletin gives instructions to inspect for corrosion and cracks in the crown fuselage skin under 2-bay and 3-bay satellite communication (SATCOM) antenna adapter plates located in Sections 44 and 46. There could be fretting and damage to the fuselage skin finish due to a contact between the adapter plate bonding jumper and fuselage skin. Removal of finish in the fuselage skin results in exposure to corrosion, which can lead to cracks. Cracks in the fuselage skin that are not found and repaired can propagate to the point where the fuselage skin structure cannot sustain limit load. When the fuselage skin cannot sustain limit load, this can results in possible rapid decompression and loss of structural integrity.
One operator reported a 16 inch crack under the 3-bay SATCOM antenna adapter plate in the crown skin of the fuselage between STA 1601 and STA 1622 (Section 46), and S-1L and S-2L on an airplane that was 14 years old with approximately 14,000 total flight cycles. This crack was found while doing Maintenance Planning Data (MPD) inspection, 777 MPD Section 2, 53-598-00, which requires fuselage skin inspection between STA 1434 and STA 1832. As a part of the MPD inspection, removal of antennas and adapter plates are necessary to access the entire fuselage skin. Subsequent to this crack finding, the same operator inspected 42 other airplanes that are between 6 and 16 years old and found some local corrosion, but no other cracking.
Boeing has performed metallurgical fracture analysis of the section of the fuselage skin with the 16 inch crack, which was sent in by the operator. The damaged fuselage skin showed that the braided section of the bonding jumper cable was contacting the skin. The contact between the bonding jumper and fuselage skin results in fretting and removal of the fuselage skin finish. The removal of finish results in exposure to corrosion. The damaged skin panel showed severe exfoliation corrosion in the area where the braided section of the bonding jumper contacted the skin. The fracture analysis showed that primary crack initiated at the area of the exfoliation corrosion. The analysis also showed that cracking progressed by intergranular stress corrosion partially through thickness for 13.5 inches along the interior surface of the skin. Further propagation of the crack through to the exterior surface occurred by fatigue.

In addition, Boeing has performed an analysis of SATCOM antenna installations. The installation drawing for 3-bay SATCOM antenna in Section 46 show no clearance between the fuselage skin and the fastener attaching the SATCOM lug adapter plate to the bonding jumper. Due to the lack of clearance, the fastener may come in contact with the fuselage skin. Furthermore, the fastener is located between stringers where the fastener can have a contact with the fuselage due to pillowing out effect when the fuselage is pressurized. The fastener contact with the fuselage skin results in fretting that causes removal of the fuselage skin finish, which results in exposure to corrosion.
Boeing has also determined that there are 2-bay and 3-bay SATCOM antennas that are installed at two locations.
The "2-bay" and "3-bay" terminologies are used to describe the length of the antenna in terms of frame bays.
The 2-bay SATCOM antennas are 2 frame bays long and are installed in Section 46. The 3-bay SATCOM antennas are 3 frame bays long and are installed in Section 44 or Section 46, or both. Airplanes can be delivered with either 2-bay or 3-bay SATCOM antenna in Section 46 as a primary option. If a SATCOM antenna is installed in Section 46, additional 3-bay SATCOM antenna in Section 44 can be installed as a dual option. The analysis showed that both 2-bay and 3-bay SATCOM antennas in Sections 44 and 46 can have similar issues related to bonding jumper and the fastener contacting the skin that results in fretting and removal of fuselage skin finish.
The fretting and presence of corrosion are factors that can lead to fuselage skin cracking.
This service bulletin gives instructions to inspect for corrosion and cracks in the crown fuselage skin under 2-bay and 3-bay SATCOM antenna adapter plates located in Sections 44 and 46 of the airplane.
Boeing Service Related Problem (SRP) 777-SRP-53-0418 is related to this service bulletin. A future service bulletin will be issued to give a terminating action for the continued inspections given in this service bulletin.
NOTE: There has been a production change to the bonding jumper installation for 3-bay SATCOM antennas in Section 44 at line number 1068 and on, and in Section 46 at line number 1077 and on. There has not been a production change to the bonding jumper installation for 2-bay SATCOM antennas.
