SUBJECT: FUSELAGE - Section 46 Skin - Fuselage Skin and Backup Structure Inspection and
Repair at the Lower VHF Antenna Cutout at Station 1197 + 99, Between Stringers 39L
and 39R
BOEING RECOMMENDS THAT EACH OPERATOR EXAMINE THIS SERVICE BULLETIN IMMEDIATELY.
CONCURRENT REQUIREMENTS
None.
BACKGROUND
Accomplishment of the inspections in this service bulletin will make sure that cracks in fuselage skin around the
VHF antenna and internal backup structure at station 1197+ 99 are found and repaired. If not repaired, cracks
in the fuselage skin and/or internal backup structure could result in unscheduled repairs.
Two operators have reported cracks in the section 46 fuselage lower skin around the periphery of the VHF
antenna baseplate at station 1197+99. One operator reported 5 cracks with a maximum length of 11 inches,
found on an airplane with 38,804 total flight-hours/34,929 total flight-cycles. Another operator reported a maximum
crack length of 9.5 inches, found on an airplane with 60,467 total flight-hours/29,185 total fight-cycles. Boeing
investigation has revealed that the fuselage skin and/or internal backup structure cracks are attributed to fatigue.
This fatigue is the result of bending loads in the skin, which are caused by vibration of the antenna in flight. No
operator reported crack findings for the backup structure.
This service bulletin gives instructions to do detail inspections for cracks, and repair if necessary, of the fuselage
skin and internal backup structure at the VHF antenna at station 1197+ 99.
Boeing Service Related Problem (SRP) 767-SRP-53-0323 is related to this service bulletin.
