PROBABLY UNRELATED MISINFORMATION: Is the mention of an AD related to 777 cracks (AvHerald comments) of interest here?The only useful link is to [Federal Register Volume 78, Number 187 (Thursday, September 26, 2013)] which I'm not sure how to conjure up.
Yup, seems likely to be routine airplane-safety business. Here's part of the text of the publication of the intended AD:
We received a report of cracking and corrosion in the fuselage skin underneath the SATCOM antenna adapter. During a maintenance planning data inspection, one operator reported a 16-inch crack under the 3-bay SATCOM antenna adapter plate in the crown skin of the fuselage on an airplane that was 14 years old with approximately 14,000 total flight cycles. 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. Cracking and corrosion in the fuselage skin, if not corrected, could lead to rapid decompression and loss of structural integrity of the airplane.
