Commercial Airplanes 747 Service Bulletin ALERT SummaryNumber: 747-53A2876Original Issue: October 22, 2014 ATA System: 5331 SUBJECT: FUSELAGE - Skin - Section 46 - Crown Skin Under Dorsal Fairing - Inspection, Repair, and Modification

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 Accomplishment of this service bulletin will detect skin damage from the dorsal fairing forward of the vertical stabilizer. The fuselage skin is subject to skin damage in the area of the dorsal fairing which can lead to cracking.
Undetected cracking in Section 46 could reach sufficient length to cause in-flight depressurization of the airplane.
During inspection for skin damage due to wear from the vertical stabilizer seals in accordance with Service Bulletin 747-53A2478, two operators found significant skin damage from the dorsal fairing just forward of the area inspected by Service Bulletin 747-53A2478 at Station (STA) 2280. The two airplanes with damage had 45,707 total flight hours and 71,702 total flight hours.
Boeing has determined that the skin damage occurred from inadequate clearance between crown skin and the lower aft corners of the dorsal fairing. Affected airplanes are limited to line numbers that were delivered with or retrofitted with 174U9000 series dorsal fairing assemblies. Airplanes with other dorsal fairing configurations are not expected to develop skin wear.
This service bulletin gives instructions for operators of affected airplanes to inspect the skin for wear under the dorsal fairing and repair any damage that may have already occurred. This service bulletin also gives instructions to measure the clearance between the crown skin and lower edge of the dorsal fairing, and trim or adjust the dorsal fairing to provide more clearance, as necessary. Accomplishment of these actions will ensure that skin wear from the dorsal fairing does not lead to cracking and possible depressurization of the airplane.
Boeing Service Related Problem (SRP) 747-SRP-53-0442 is related to this service bulletin.

Do a detailed inspection of the skin under the dorsal fairing for wear or cracks.
If no skin crack or wear is found, apply teflon coating to the skin under the dorsal fairing and repeat the detailed inspection for skin wear or cracks at the interval specified. As an option, install Corrosion Resistant Steel (CRES) rub strips under the dorsal fairing as a preventive modification.
If any skin wear is found, do a blend repair or install a repair doubler depending on the depth of the skin wear.
If any skin crack is found, install a repair doubler or contact Boeing for repair instructions and do the repair.
If a blend repair is done, do initial and repetitive post-repair detailed and high frequency eddy current (HFEC) inspections for cracks in the blended area of the skin, and do detailed inspection for wear or cracks in the unrepaired areas of the skin under the dorsal fairing. If any crack or wear is found in a previously repaired area, contact Boeing for repair instructions and do the repair.
If a repair doubler is installed, do initial and repetitive post-repair detailed and HFEC inspections for cracks in the repair doubler, and do detailed inspection for wear or cracks in the unrepaired areas of the skin under the dorsal fairing. If any crack is found in a previously repaired area, contact Boeing for repair instructions and do the repair.
Upon re-installation of the fairing, make sure the clearance between the crown skin and the lower edge of the dorsal fairing meets the gap requirements specified in the applicable Aircraft Maintenance Manual (AMM). If necessary, trim the lower edge of the dorsal fairing or adjust the installation shims as specified in the AMM in order to meet the gap requirements.
