Mel, have you looked at the mentioned Notification?
You can find it HERE
The problem appears to be that the FAA's placard requirement hasn't met the requirements of the consensus standard, so the FAA is changing their requirement.
The last page of the notification includes an E-mail sent to Van's by Terry Chasteen detailing the amendment to 8130.2J that is in process right now. Their desire is that all certifications going fwd have the new placard (even though 8130.2 hasn't been amended yet) and that the letter would hopefully satisfy the contention issue until that happens. If that isn't the case, I imagine a call to Terry will clear it up.
