Bo/Mike,

We can provide Jim the answers to item #1 and item #8.  We can provide a 
partial answer for item #2 but we cannot give a complete answer since we do 
not have VisuPro data all the way back to the commissioning date.  The 
partial answer to #2 will center on total operational hours (SOT) and the 
capacity factors by month.  

We do not have any visibility into item #10 so we are unable to help on that 
one.

I understand a similar request for information will be coming in for turbine 
#30.  We should be able to provide answers for those questions as well.

Best Regards,
Hollis

investigating the cause of damage immediately  
we request answers to our following  questions:

? 

what is the date of commissioning of WTG #  79?  
no. of operating hours at???  nominal load??? and at partial load  
are all teeth of the gearwheel damaged or a  segment only?  
does the pinion show comparable damage ?  
is a bearing damage visible ?  
are deformed components or casing parts visible in  the surroundings of the 
affected gear stage?  
is it possible to get photos of the surface  structure?with higher resolution 
?  
for damage diagnosis we require detailed WTG data  of the last 7 operating 
days, particularly of the last 24 hours before  stop,??i.e. gearbox temp. and 
speeds, power, wind speeds, 
are metallic particles in the filter?  
we need? the torque measurement results?  of the reference gearbox in Trent 
Mesa
