Nice looking 150 in....ARIZONA!

But...WHO DOES THIS AND WHY????......
"Engine 875 SMOH, 75 since top-end"On an engine that has almost 1000 hours to go til TBO and they topped it??? How were they flying it that it needed that? or were they NOT FLYING it? Always amazes me that folks think if one cylinder goesbad they believe ALL 4 SHOULD be replaced!!
