Flight International reports in the current edition that Cathay Pacific will update all 21 747-400's to the updated RR RB211-524 G/H-T, this is Trent 700 hybrid. The updated engine is reported as having a 2% SFC advantage, and larger TGT margins as well as being 365kg (about 800 pounds) lighter. In addition Cathay apparently has 8 spare engines that will also be upgraded. It has been no secret for some time that many airlines have been unhappy with fuel economy and reliability of the RB211-524G/H engine. "The existing engine has not retained performance as much as we would have liked" said Derek Cridland, Deputy Engineering Director at Cathay. The hybrid is an RB211-524G/H engine with a Trent 700 high pressure turbine, Combustor and compressor. These parts can apparently be fitted to the existing 524G/H engines during major overhaul. While it was reported that Cathay will be re-engining the entire fleet, the article makes it clear that the new components will simply be fitted to the existing engines. Neither RR or Cathay are willing to talk about how much money is involved in the deal.
