The Arriel 2 series engines fitted into any helicopter operating in hot climates seems to have a problem. Bristow have had to replace many engines in their EC155s in Nigeria, ACN have had to replace many engines in their S76C+s in Nigeria and Schreiner had to replace both engines in their 365N3 in Cameroon. I heard that the same problem exists/existed in Hong Kong and Macao - anybody working there care to comment? What about the machines in Dubai as well?
If only P&W could come up with an updated engine for the 76B, producing about the same power for a similar fuel burn to the Arriel 2 series, Sikorsky could ditch the problematic Arriel 2 series engines (though I'm sure Eurocopter will always go for a French engine over an American one
)
