Commercial Airplanes 777 Service Bulletin SummaryNumber: 777-57A0097Original Issue: January 10, 2014 Revision 1: May 04, 2015 ATA System: 5720 SUBJECT: WINGS - Outer Wing - Underwing Fittings Sealant at Wing Panel Gaps - Inspection and Repair

CONCURRENT REQUIREMENTS None.

BACKGROUND Accomplishment of this service bulletin will find if sealant was applied to the wing skin panel gaps above the underwing fittings. Missing sealant in the wing skin panel gaps above the underwing fittings can allow undetected corrosion to develop in the wing skin panels above the underwing fittings. Undetected corrosion in the wing skin panels above the underwing fittings can result in undetected fatigue cracks in the wing skin panels. Undetected fatigue cracks in the wing skin panels can result in the loss of limit load capability of the wing skins and structural failure of the wings.

Boeing found that sealant may not have been applied in production to the wing skin panel gaps above the underwing fittings on certain underwing fittings on certain 777 airplanes. Sealant is required to be applied to the wing skin panel gaps above the underwing fittings prior to installation of the underwing fittings. A review of Boeing installation records found that sealant may not have been applied above certain underwing fittings on certain previously delivered and in-production 777 airplanes. The affected in-production 777 airplanes have been inspected to make sure sealant is applied to the wing skin panel gaps above the underwing fittings. Production installation procedures have also been addressed to make sure sealant is applied to the wing skin panel gaps above the underwing fittings on future 777 production airplanes.

This service bulletin gives instructions to inspect and restore the sealant in the wing skin panel gaps above the underwing fittings. If sealant is missing, this service bulletin also gives instructions to inspect for corrosion in the wing skin panels gaps to prevent possible fatigue cracks in the wing skin panels, loss of limit load capability of the wing skins and potential subsequent structural failure of the wings.

NoSpecial Tooling Required ACTION Do a Detailed Inspection (DET) of the wing skin panel gaps above the underwing fittings for any missing sealant, on the left wing (applicable to Groups 1,3) and on the right wing (applicable to Groups 2-3). If sealant is missing, do a DET of the wing skin panel gaps above the underwing fittings for corrosion. If any corrosion is found, contact Boeing for repair instructions, do the repair, and restore the missing sealant and the sealant that was previously removed to gain inspection access. If no corrosion is found, restore the missing sealant and the sealant that was previously removed to gain inspection access. If sealant is not missing, restore the sealant that was previously removed to gain inspection access.
