No need for eveybody to get their knickers in a knot over this one. At this juncture, all machines affected by this SB and AWD have been inspected and where required repaired and/or hauled off to the beer can factory.
For those having access to the manufacturers fleet page, the applicable SB was issued 14 March 2002 and applied to everything from the 07s, right up to the MD 90s. Time to complete the SB depended upon TCSN of the machine. These ran from 30 days to 100 flts up to 90 dyas, 300 flights.
Since the SB was mandated by "incorporation of reference" all civil authorities issued the FAA AWD and mandated these actions. So, in essentially, all aircraft still poking holes in the sky, are done.
Basically, the inspection stated that a DVI,(detailed Visual Inspection) was to be done all lap Joints, and anything noted would require LFEC or MFEC Inspection ( Low Freq or Medium Freq Eddy Current).
While this SB was kind of a surrise, the manufacturer has previously called out numerous SBs on this particular area of the aircraft. Generall, the AME's check these areas on every turnaround, B check, A Check as well as indepth inspections every C Check.
So every body relax, get back out there, get them turnin and burnin and go back to making money!!
Stay safe y'all, and ask lots of questions!!
