From an earlier thread over a year ago:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Have you seen an aircraft pricing guide? I have one sitting on my desk, actually from two different sources,
and they both show RB211-524 powered 747-400s and 767s as +20% less value than a comparable GE or Pratt.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
744 RR engines are always are having problems with :
1. attrition liner damage/replacement
2. ogv infill panel separation/ogv cracking
3. titanium acoustic panel delamination
4. ice breaker panel delamination
5. thrust rev motor failure
6. flex drive cable breaking/seizure
6. thrust rev sense line failure/leaking
7. bleed valve sense line failure/leaking
8. selector seq valve malfunction
9. sense line clamp failure
10. interservices structure cracking
11. N1 fan vibrations
747-400 GE engines nothing goes wrong except the odd thrust rev does not deploy and a bit of anti ice fluid poured into the cdu can fix this.
GE engines a little bit harder to work on with but a better fuel burn than RR.

I always seek out the local P&W rep and tell him how much I admire any Pratt engine built before 1950!
