Yes, flogging these 25 year old GA aircraft and expecting them to deliver acceptable reliability is just too much. How many buses and taxis are 25, even 30 years old? but; no; in aviation, you get BACK OUT THERE and FIX that PA32 or that 402B!!!! with this antiquated NAVCOM that has been repaired about 1500 times in the last 30 years and can be expected to perform for about a week or maybe not even at all......
