Framer states:
When our pilot makes a mistake, the Engineer needs to have the time and brain space to catch it. When our refueller makes a mistake, our Engineer and pilot need to have the time and brain space to catch it.
When the airframe / engine designer makes a mistake with a vulnerable design, those listed above also need to catch it.
With random and unpredictable damage to the fuel system, hydraulic system, airframe and U/C in this instance, the outcome could have been much worse.
A critical weakness has been exposed, and the overall management of this systemic failure needs to be recognised and addressed. This is about much more than six-monthly drills in the sim.
