Touchdown! Greaser!
One of our Archers is in annual right now, and they discovered that ALL FOUR cylinders are cracked!
What would cause all of them to crack at roughly the same time (at least since last annual, we also did a "modified" 100-hr about 2 months ago but I don't know how closely they check the engine on that)? Are cracked cylinders common, or is this indicative of another mechanical problem or a pilot problem?
This engine has about 1600 hours SMOH, and it was torn down for a prop strike inspection about 3 years and 500 hours ago. (I don't know if it has ECI cylinders or not - What was their problem again? Our cylinders were at least not subject to the AD)
The only recent symptom was somewhat increased oil consumption, but not way out of line for an engine that old. Power seemed good. We also did have all four bottom plugs replaced on the 100-hr a couple of months ago, after some significant fouling issues this last winter.
