Annuals Vs engine change

I think this thread is done.
 
Is that what normally happens?

If there is any thing during the engine swap, that requires a STC or field approval, it requires a 337 to be filed.

One out, one in, same make and model called for on the TCDS ,, no. it's simply a log entry in both the A/F and Engine logs.

so.... that's why you're annualing the engine each time? :yikes:
