From what I've heard, there was a service letter (not sure that's the proper name) that Fedex complied with that UPS didn't comply with due to cost or they just didn't think it was important. UPS tends to not do things unless the FAA mandates it (think part 117 or that UPS kept flying the jet for days after this crash until the FAA grounded the fleet). Fedex had an improved gizmo installed that wasn't mandated by the FAA, it was just a suggestion from Boeing. My understanding was that it wasn't strongly pushed by Boeing, either. If you own a small plane, part 91, do you just do the AD's or do you do service letters, too? Of course, airlines are held to a higher standard than my Cherokee, but I must admit that I don't follow service letters.
