"Only 3 Failures"?
Per AvWeb:
3 failures of 257 in service seems like quite a high number to me.

Dont know if all these reported engine problems are on engines by superior or Lycoming with the German crankshafts.
I am waiting. The AD according to Justin does not effect experimental aircraft so there is no time limit on how many hours you can fly.
It is just that knowledge in the back of your brain
On the other hand Justin did say still there were only 3 failures and all on Cessna 172’s that would have been Lycoming engines.
Per AvWeb:
Some 257 four-cylinder Superior and Lycoming engines are now subject to a new airworthiness directive requiring crankshaft replacement within 25 hours.
3 failures of 257 in service seems like quite a high number to me.
