Is there a register of repaired and damaged airliners anywhere which ordinary passengers can consult?
Such a database has been suggested. Those in authority responded in lukewarm fashion.
Such a list would be useless, so quite reasonably, there isn't one. Even well informed engineers would not be able to use such a device to improve their own safety when travelling, so members of the general public would not stand a chance. The reason is that an aircraft is a no more than a collection of components. The big bits (spars, major frames and sub-assemblies) more often than not stay together, but virtually everything else is replaceable. On a regular basis, each airframe, warts and all, is certified as being fit for flight by qualified engineers. Knowing that an aircraft has had a repair in the past tells you zero about the current status of the aircraft. The industry's record speaks for itself in this area and there are very few aircraft which haven't had repairs.
To guarantee a safer travel experience, think more about the hygiene in your own kitchen, the serviceability of your car, the quality of your driving, the roads you drive on, the time you travel etc. Additionally, avoid third world airlines - If the aircraft has an EU registration you should be alright. I for one would be more than happy to travel in this aircraft once it has been declared serviceable.
