I'm a frequent flier and I'm scared. I try avoid companies with low standards reading all the news about incidents related to the use of used or counterfeited parts, lack of maintenance, etc. But now it's clear that, in times of low cost companies, cheap airplane are requested and even the redundancy in critical subsystems is sacrificed both by the producer and the flight company that didn't pay for a "optional" that actually is a lifesaver. How many critical subsystem haven't redundancy to reduce the costs of airplanes ? Maybe some regulation in this market is needed to avoid other disaster like this one, imposing standard for the critical system and denying the routes to the airplanes that do not meet the specifications. I don't think that the market can play with human lives.
