Hello Out There, question about wing spar AD

Hi all,

Just found this forum. Logged a couple hundred hours in a 337 in the early 1980s. Lost my medical about 4 years ago, sold my (ugh!) Mooney TLS. Doc says I should have my medical back in about 90 days. I anticipate looking for another airplane soon thereafter. I really liked the Skymaster (in fact I was looking at them when I bought the stinking Mooney - wouldn't fit in my hangar). More importantly, my wife really likes the idea of a 337 even though she's never seen one in real life (I explained the advantages of centerline thrust). So, I'll be mostly lurking for a while. I do have one question though. I've heard rumors of something variously referred to as a "tail boom AD" or a "wing spar AD" but haven't been able to find much information. Can anyone educate me on this matter? Thanks in advance!

Regards,
Jim
