Still nothing regarding a forthcoming AD, other than some sources are saying inspections are "required" (can't happen w/o AD). A Seattle paper is reporting that the Manufacturer is "requested" to inspect...
From a practical standpoint, an OEM mandatory service bulletin (SB) has nearly the same leverage as an AD - in that the manufacturer's warranty may be denied if the operator fails to comply with the SB requirements.
And a strongly worded SB will likely hit the street before FAA can process an AD.
