Why going overboard with this question. There was a request for an image of a crack in the spar area. When I read that I had immediately the image from the Skyport site in mind. I have not seen a photograph of a crack in a spar. If someone has one, please send it to me. The crack in the rib that we are now discussing is a result of a bad design. The center section flexes at least a little on every landing, and the rib needs to give at that point. But due to the cutout for the spar, the rib is weakened here, can't give as much and the place for the crack is therefore pre-defined. Nothing to get exited about. This crack can develop after one hard landing, even in a brand new center section. It is a good reminder for all of us to check the area at the next annual. Even though the rib represents a structural item, I do not consider a crack there as a safety hazard. The main attachment point of the rib is in the front and the lug ,the crack is parting is not carrying the main load here.

Don't look at yours with a magnifying glass unless you want to see a crack. Lee -- Syd Cohen <[EMAIL PROTECTED]> wrote: Whoa, Al.

I think you've got the facts terribly backwards. Syd AJ DeMarzo wrote: Be careful what you wish for. If indeed Univair found it necessary to address a problem with a crack in the spar, the ENTIRE FLEET, that's right, the ENTIRE FLEET could be grounded. Overall statements of what Univair should be doing must be avoided at all costs. Cracks should be addressed by individual mechanics based on the crack guidelines already published, but which are now teetering. When the current stock of spars are gone, what do you think it would cost for another run? Are you willing to pay $11K for the parts? Never wish for or agree with the establishment of an AD. I'm still reeling at the imbecile with the EOC who was interviewed about a pending AD and agreed that it was a good idea. When asked these types of questions, one should consider a buzz off and let the structural engineers address it.

I don't believe that it is a fix for a cracked rib - only a reinforcement to prevent such crack. The crack is in Glenn's spar cap and that is the crack that I think Univair should address a fix for.
