to me it doesn't make senseInteresting point. I looked at the price of the RD93 and the EJ200. The former was quoted at 2.5 million and the latter at 12.5 million.However when you are looking at 4000 hours total life vs 40000 hours the Maths starts making sense. Which makes me ask the next question that if it was the case why did we go for the RD series in the first place when the prospect of 2-500 engines would have enticed anyone into selling.
A
the air frame of an aircraft last about 4000 hours standard, yes it can be upgraded to 8000 hours but that is essentially rebuild of all the wings and tails just keeping the fuselage.
so assuming thunder will go to full 8000 hrs and assuming that rd 93 cannot be over hauled beyond 4000hrs, than rd 93 even if replaced will cost 5 million(2x2.5) vs 12 million. now this doesnt include maintenance cost
