DV,
The 227 incident was caused by a ruptured SCP pipe. All of those pipes on the other frames were replaced following that incident, thus eliminating the possibility of it happening again. So, the SCP was re-introduced as it was believed safe to operate again. The question that should be asked is why was the hazard of the 1 tank blow off being in proximity to the pipe not noted earlier?
Hindsight is a wonderful thing, this is an aicraft that was built decades ago, in a different safety regime. The designers missed the hazard, A&AEE missed the hazard, the Ground Engineers missed the hazard, us aircrew missed the hazard. Indeed, 25 years of AAR never highlighted the hazard until 230. So, let's not be too hasty pointing the finger of guilt at any one person.
