Report on 787 batteries assigns some blame for flaws
Flaws in manufacturing, insufficient testing and a poor understanding of an innovative battery all contributed to the grounding of Boeing’s 787 fleet last year after a fire in one jet at Boston’s airport, according to a report released Monday by federal regulator (www.nytimes.com) さらに...Sort type: [Top] [Newest]
It depends on which article you read but the first one posted before this one does not say it should not have been certified just this article. It says that it was not tested enough or proplerly only in the other one. Anyway this is a repost.
At least this one contained a link to the report itself.
Well, although the root cause has never been identified, it says something for the fix that no publicized incidents have happened. You don't know if there was another problem found and fixed as well but whatever they did, so far it has worked. Question is, not finding the root cause, if another short occurred, would the fix stop the aftermath?
The root cause problem is always the one working on anything is what I always looked for. What caused the failure and they didn't find it still bothers everyone involved am sure. Like you being a pilot knows, is it going to crop up again? The Boeing hard over rudder problem was one that finally got cured after several problems and at least one crash.
2 crashes - UAL 585 at Colorado Springs and U.S. Air 427 at Pittsburgh. The investigation into 427 was where they found the problem I think. But, you are correct, they looked and looked into 585 and couldn't find it. It had to happen again. It was about 3 years but it did happen. This could too.
Actually I believe it was a third incident -- Eastwinds Flight 517 -- that revealed the PCU as the cause of the two crashes you cited. The fact that the pilots were able to recover and land safely provided NTSB investigators with a whole aircraft and live witnesses.
Well, I think they found the problem on 427 but did not tie them altogether until the Eastwind. That was a couple years later and after it is when Boeing did the fix.
