I noticed that AD2015-16-07 just dropped out from the AD Biweeklys. It's on the C406 Rudder pedal torque tubes and is a "Before further flight" AD.
We seldom see the C406, but it has commonality of parts with the C421C, and C425 in that system..
You may want to look the rudder pedal torque tubes over closely in any of the aircraft to do due diligence. I have been unable to access the ASI Aviation SB # F406-104, dated July 28, 2015. If you google that SB, all I've been able to get is the AD. I've emailed the FAA in KC to try to access it that way.
