Even if they were there but 'working' (sic) or insecure, there is no doubt this should have been picked up during "A" inspection scheduled maintenance or other preventative inspection sequences. Does anybody know which sub-contractor produces the horizontal- stab' sub-assemblies, bearing in mind that they are still subject to an acceptance check by Boeing Quality ? Is it confirmed that the hinge bolt was missing ? Usually, failsafe design will accomodate the omission of one attachment path, but for the media to speculate on both missing fasteners AND an attachment bolt seems like wild rubbernecking. I have not seen the FAA emergency A.D. and am not sure wether they emphasise control attachment or skin integrity? >From : email@example.com " Slow to erect, quick to topple -- A maverick gimbal ".
