'Spanish', it really is not unusual to take parts out of an aircraft, re-condition them etc, and fit them back in. These are probably what he means. This is pretty standard practice and the engineers who do it are good lads. I have never been worried about getting in a jet where there are 'nearly new' parts. How many people drive around with re-conditioned engines?
I would suggest it is the wrong time for you to make any inference. Family and friends will probably read this thread, our thoughts are with them.
