As someone who is only a passenger, may I say that I would FAR sooner all minor perceived faults were reported and checked. I don't care if I am delayed as a result I just want to arrive at my destination safe and still breathing. I make sure my car is properly maintained but I have to rely on the airlines to do the same for the aircraft I fly in. I may not have aircraft technical knowledge, but I use highly specialised life-support and monitoring systems on a daily basis and I would hate to think that as a result of someone being unhappy about the perfomance of a piece of equipment and sending it for checking, it was deemed that our equipment was faulty and unsafe. I worry more about things like a short article I read some years ago, in which an airline operating locally was criticised for abysmal maintenance of their aircraft. If I remember rightly, one engine part was so badly worn that the people making the inspection expressed surprise that the aircraft hadn't fallen out of the sky! Great! They fly over my house. Carry on reporting your faults and acting on them, it is reassuring not off-putting.
