Is there a problem with the B777?
A while ago I was concerned about the lack of progress the Air Accident Investigation Board (AAIB) seemed to be making on the cause of the British Airways B777 crash at Heathrow on 17 Jan.
Read what I said (in a rather self-indulgently long post) at the time.
But then, finally, on 17 Feb the AAIB bulletin report came out saying there were "no anomalies" with the digital engine control system and that the investigation was focusing on the fuel supply.
Now read this - American Airlines have pulled a B777 out of the fleet to investigate why one of its engines stopped responding to throttle controls for 15 secs on approach to LA on 28 Feb. (Different source for same story here)
Hmmm.
It think 'duck theory' applies to this one. If it looks like a duck, floats like a duck and quacks like a duck.... it's usually a duck.
I think this is serious for Boeing. There seems to be an intermittent problem (possibly with fuel supply...personally, I still think it's with the digital engine control system) with B777s coming in to land. Unlike un-official expert forums the aviation industry seems strangely slow to acknowledge the problem or come up with an explanation.
