There's that word " legacy " again.
It's as if it means "inherited" in a demeaning way.
As a matter of fact, one could be forgiven for thinking that if you say "legacy whatever" is a bad thing for long enough, others, ususally those less experienced, will begin to believe it. These people also believe that practices and procedures need to change to achieve efficiencies of scale when they do not.
The time that it takes to do an inspection or carry out maintenance of any kind might vary with the technology available, but the practices and professionalism used do not.
All the wisdom in aircraft maintenance has been inherited and learned, so is a valuable asset, yet some describe it as a liability.
