The engine was done in June 1, 1997. There is a stamp that the AME signed to verify the engine was now at zero time
I'd be curious to see EXACTLY what the stamp says. Only the engine manufacturer can ZERO TIME an engine. Anyone or anything else simply continues the total time on the engine and would note the time since overhaul as being "zero", which is really meaningless, as it has no legal standing.
If you are interested in what is considered an "overhaul" and what must be done to the engine to legally use this word in the logbook to describe the work, you need look no further than
Teledyne Continental Motors Service Information Letter SIL 98-9A [
tcmlink.com] which covers all Continental engines. If the work done doesn't meet the criteria set forth in this Letter, then the work done was simply an IRAN (Inspection and Repair As Necessary)
