The AD lists the affected King Airs by serial number, which I have included in the box (right). There’s your answer on “who” is affected.
What Happens?
To comply with this AD, the wings must be removed ... yes, removed. Of course airplanes are disassembled and reassembled every day, so what’s the big deal? If it’s your airplane, it’s a huge deal. When the wings are pulled off a King Air, all the electrical connectors for lighting, fuel quantity, etc. are disconnected; all the plumbing for the fuel system is disconnected; and all the cables for the control surfaces (ailerons, aileron trim tabs, flaps) are disconnected. It’s major surgery.
Once the kit is installed, everything is reassembled and the wings are put back on the airframe. Of course, that is easier said than done. Things always come apart faster than they go back together.
Where To Go?
If I’m asked where to take a King Air for this job, I always recommend Textron Aviation’s service center in Wichita, Kansas (KICT). If there’s a King Air out there that is affected by this AD and has not yet had the kit installed, I would take it there. This is not the time to shop around for a “good deal.” The service center there has all the necessary equipment and experience to get this Wing AD done properly.
