Thanks daftpudding for those pics! The BA 777 is now behind a fence so that nosy passengers and pilots can't see it anymore...  The pictures show nicely whats behind the fence... Cheers flightwork.com - International Pilot Network |

The latest AAIB report can be found here: http://www.aaib.dft.gov.uk/publications/special_bulletins/s3_2008___boeing_777_236_er__g_ymmm.cfm Released May 2008 It seems all systems operated as normal amd electromagnetic interference has been ruled out. The focus of the investigation lies now on the fuel system between Tank and HP pump. |

Thanks for the update. What puzzles me is the fact that both Boeing and Rolls-Royce seem to be testing almost everything, sounds good. The results are all satisfactory and show normal behaviour, sounds shocking. Fact is that BA crashlanded one of their B777 in LHR due to an unsatisfactory and non-normal behaviour of their airplane. Gentlemen Boeing and RR: Are you waiting for another couple of crahes to get more testing data? Or is Britain censoring because Mr. G. Brown was in vicinity at the time of crash, security jammed too hard and FADEC's quit their job? There are more than 700 other B777 out there and everything runs along as if there hadn't been a crash at all. Boeing says that the B777 can connect any two points on the planet. This means, that polar routes will be daily business for airlines. Up there, it is at least as cold as it was for the BA-crashflight, therefore more "testing" data will be provided soon. No (significant) operational change has been announced. Even more, the B777 is still ETOPS approved. Engine reliability requirements for 120mins ETOPS are less than 5 Engine shut downs per 100'000h of operation fleetwide. For 180mins ETOPS it's less than 2/100'000h. Sounds all fine, but sitting in the middle of the south pacific of south atlantic with just Diego Garcia and Cocos (Keeling) Islands or Ascension Island and Napoleons last holiday resort island barely in reach is not very reassuring. Now, was this particular scenario counted as a double engine failure? If so, BA should not have 180min ETOPS anymore. Any BA-777 drivers out there? Somehow fishy to me. Imagine a grounding of the B777 fleet... Money rules the world. Being statistically on board of one of these crashing airplanes is negligible and affordable. In short: We all trust in their engineering and testing abilities, don't we? [This article was edited 1 times, at last 02.06.2008 at 11:45.] |

The focus for the accident flight and an inflight rollback have been on the FOHE Fuel Oil Heat Exchanger design in relation with fuel icing. Here's the explanation and fix. Hopefully this is the end of the story!  |
