Airlines are paranoid! Any mention of a possible safety problem is going cause delays or cancelation.
If I'm on a plane, paranoid is good.
Some years ago, a KAL plane landed in Germany, Frankfort I think. During the preflight inspection before they took off, a mechanic saw a crack in a turbine fan blade -
wired together! They got more than paranoid. The plane was instantly grounded until KAL could install a new engine.
