one of the F.1074 Stiffener was wrongly positioned during match drilling, therefore the the first hole on the hidden end was too too close to the edge.
As this was discovered after completely disassmembling the tailcone it was not possible to matchdrill again.
Therefore i used the wrong stiffener to matchdrill another one after cutting longer. In some areas the holes seem to be too close to the the siffener flange and we will need to check if after the priming the stiffener will fit.
