Even the older machines would need to sustain 571 hours pa to reach 4000 hours in 7 years - not taking the downtime into account for maintenance and 2000 hour rebuild.
If the local register is anything to go by, the 66 seems to be used for lighter (often business or recreational) use.
There can't be many that have hit 4000 hours, given the relative youth of the type.

There have been around 10 airframes reaching the 2000 hour overhaul (3 in Russia plus one crashing at 1995 hours, 2 in Nigeria and the remainder around the world).
The average engine 2000 hour PMI is $95,000 which includes the stage 1 and 2 wheel replacement. For the 4000 hour, you will need to factor in the stage 3 and 4 wheel replacement at $31,000 plus some additional wear and tear, the engine should be around $145,000 for the 4000 hour PMI.

Ok genius, "well over two years" lets say close to three years.

3 X 12 X 100 = 3600, so yeah must be getting close to 4000... at that rate 4 months to go, or maybe I'm not 100% on the dates, and they have done four years which would then be well over 4000!!! :D

Figures
 

Thanks Chris,

Just what I wanted to know.
