I note that from the RHC website that the R66 Operating costs lists both airframe & engine have only 2,000 hours life rather than the 2,200 hours on R22 & R44, see below,

However that was not the main point of my post here which concerns how RHC calculate the overhaul cost element of both R22 & R44. Taking as an example on the Raven II overhaul reserve costs are quoted as $83.18 per hour, which multiplied by the 2,200 life = $182,996 see below

but if you look at the overhaul section of the RHC website for the Raven II, see below
http://www.robinsonheli.com/price_li..._pricelist.pdf
you see that the basic overhaul cost is given as $210,000
That is a difference of $27,800 or $12.64 per hour on the overhaul reserve bringing the hourly overhaul allowance up to $95.82.
Similar differences apply to the R22.
Now, am I missing something here? I am unable to see how both figures can be correct
Are PPRruners able to enlighten me and should we take as gospel the overhaul reserve figures quoted by RHC for the R66?
