[SystemSafety] NTSB report on Boeing 787 APU battery fire at Boston Logan

[Matthew Squair]

As you both point out there's plenty of information out there. The fruitful
question IMO is what were the organisational, regulatory and cognitive
factors were at work to make them disregard it? Plus they (the 787 team)
and the FAA completely misunderstood the value and limitations of testing
in their specific context.

I wrote a bit on where I thought they'd lost the plot when the interim
report came out. In fact I wrote quite a bit, as it's an excellent case
study of experimenters regress amongst other things, so perhaps we should
really thank the players*?

So could the assumption have been validated as it should have been?


Simplest way to test this is to do a literature search.


You didn't mention Linden's Handbook of Batteries, ed. Reddy, McGraw-Hill,
4th Edition 2011, Ist
edition 1984. Then there's Ley and Bro, Battery Hazards and Accident
Prevention, Springer, 1994.
Then there is Daniel and Besenhard, Handbook of Battery Materials, Wiley
VCH, 2nd edition 2011,
first edition 1999. As far as I can tell, they are required items on the
bookshelf of any battery
person and they are on ours too. All of them deal with the issue of thermal
runaway of lithium
batteries, and the first two with how this is affected by design. Then
there are the many annual
conferences on batteries.

Or you can simply ask people who know. Like, any one of those authors of
the thousands of papers,
some of whom are very distinguished scientists indeed, as well as being
well-known.
