Ummmm, with the greatest of respect, this is not the truth, the whole truth and nothing but the truth. There is a condition known as "infant mortality" that applies to all systems including aircraft systems and structures.
New planes, like new cars, often have defects resulting from build errors. Then of course every time you maintain an aircraft you have infant mortality all over again.
There is no reason a 50,000 hr aircraft can not be as reliable as a 3,000 hr aircraft provided it is properly maintained.
Case in point many years ago was the gyros in F27 and B727 aircraft, solution to increase gyro life was ...... don't change gyros. Damage to the bearings during installation (brinelling) was the major cause of failure.
To put it another way, I'd rather fly in a 30 year old aircraft maintained by a top team of LAME's than a brand new aircraft maintained by the second eleven.
