No step or a poor design?

Guys

No matter how you package this with regard to the 10 stone weakling or the 20 stone average American inspector, the real problem is that the reinforcement bonded to the skin bay reinforced everywhere but the actual section transferring the load. One side of the cracked area has skin plus frame, the other side has skin plus factory-bonded doubler. The gap in between has skin only. Now Winnie the Pooh (the bear with very little brain) could work out that if there was a pressurisation-stress fatigue or over-weight inspector overload problem anywhere, it would happen there. (Even Homer would say DUH!)

The real question is, where are the similar "reinforced" areas on the aircraft where the local stiffness and thickness changes are so significant?

Was this a BIP? (Boeing Induced Problem)
