NTSB was able to get fuel samples from the engines......fuel was clean! #4 Engine suffered a Compressor Stall at rotate. #1 Engine had a turbine failure after being advanced to Emergency Thrust!
A couple of weeks later, the replacement plane also suffered a compressor stall at rotate. The Pratts don't seem to do well at high altitude runways. Any kind of air disturbance seems to cause the compressor stalls???
Any other operators run 747 classics out of there? Or even other heavy a/c powered by Pratt's? It would be interesting to find out if other operators have had similar issues.
