 But you still get into an aeroplane with your family,  even though they are so unreliable  (by your definition) that the engines are subject to a complete teardown and rebuild every X number of hours,  whether they "need" it or not. It's called maintenance. 
Like top fuel drag racing,  every so many runs, you replace the conrods. If their MTBF is 10 runs, replacing them at 8 is good sense.
