Crash investigators plan to remove and disassemble a General Electric engine that caught fire last week on the British Airways aircraft. (hosted.ap.org) さらに...
Glad to see there is not just a knne jerk reaction on this engine, that they seem to be leaning toward an anamoly, as in STUFF HAPPENS. That is why we have all the evac training and fire trucks on scene. Good Job gang.LOL
Anytime you have an UnContained Engine Failure it is an anomaly. I am personally guessing bearing, or Burner Can Failure... But time will tell. GE will find the answer.
GE is very sensitive to proprietary information and they will no doubt determine the cause of the failure and make any corrective action necessary to their materials and processes. My company is heavily involved in GE gas turbine work on the industrial as well as the Aero side and there are many places in my own company I'm not allowed because I'm not GE clearanced.
GE as manufacturer needs the results of the investigation to keep their fleet safe and create any repairs to their systems or processes the investigation uncovers for liability reasons. Also, the cognizant engineers are more accessible and the necessary labs and tooling is available at the manufacturer.
The investigation is handled per CFR Title 49 Subtitle B Chapter 8 Part 830 and 831 Specifically §831.11 Parties to the investigation.
(a) All Investigations, regardless of mode. (1) The investigator-in-charge designates parties to participate in the investigation. Parties shall be limited to those persons, government agencies, companies, and associations whose employees, functions, activities, or products were involved in the accident or incident and who can provide suitable qualified technical personnel actively to assist in the investigation. Other than the FAA in aviation cases, no other entity is afforded the right to participate in Board investigations.
You can read all about it here. http://www.ecfr.gov/cgi-bin/retrieveECFR?gp=&SID=01770d8e6dbe5ed726e57ed4591fa8cd&mc=true&r=PART&n=pt49.7.831
Great response. And THAT is why this is good news, AND worth mentioning, Joel. The NTSB could have just as easily made the decision to hold the investigation entirely in their own hands. Nobody was seriously injured or killed, so allowing GE to conduct the investigation ensures the greatest chance of correction and mitigation of future occurrences without conflict of interest.
You are correct my friend in that there is a shortage of reasonable and prudent people in this day and age. GE could send an on site team as they have but tis far better to send it to the factory where all is there that is needed to dissect it and you can bet they will.
I doubt that, problem there is that the lines go to the nozzles that are outside of the hot section... If there was a leak there, any fire or spark would have gone out the tail pipe...
The GE 90 is a growth project engine, so the dash number is important. if it's a -115 then the design is one that is pushed to the limit on thrust. I once asked the long time head of Delta's Engine shop how he viewed GE vs Pratt engines and he said the GE design was very precise but the Pratt was more robust
Obviously there was a problem with #1 engine. It burped but they have 2 halon extinguishers to put the fire out. It was 103 degrees in LAS. Imagine what the runway temp was. Like I've said before, you abort at V1 and stand on the brakes. Hence, the black smoke and fire wrapping around the fuselage. This is just my opinion but the fire was caused by a "Wheel Well" fire. They blew the tires. Been there. Good job to the crew.
No way.... There were engine parts found on the runway trailing from the time of the abort... This had nothing to do with the wheels or breaks. It was an internal engine break down... Something came apart from the internal core of the engine. That much has been proven. Make note that the engine cowl on the outboard side of the engine is where it had started.... If it had been the tires and breaks the initial problem would have been on the inboard side of the cowlings.
This is Smart on the part of GE... That way we will NEVER KNOW what actually happened. I wonder how much of a BRIBE they paid the FEDS for this GIFT???
Just for a heads up.. During the entire testing process, the investigators are with them the entire time...Also remember the rudder issue of the 737... Boeing and the Feds worked on that problem and the Boeing engineer pointed out the real problem with the actuator. There is no pay out or bribe in these situations... They want to get this fixed and make sure this does not happen to anyone else. I feel that your comment was in bad taste.
