Trying to grasp the AD for wing spars

[YankeeClipper]

Sorry, I was after whether the issue raised in that SID should concern 337 owners, as in to bother, worry, or raise doubt--as opposed to applicability. With the costs involved, some are inclined to suspect revenue generation, while others might feel there is a genuine risk afoot.

But that was helpful information in any case ... thanks Ernie.
