Is the 787 a "lemon"?
I read today that a “bad” battery batch has been ruled out, and that attention is now focused on the monitoring and control circuits for the battery pack. It is increasing looking like Boeing is going to have to do a redesign and re-certification, meaning that the fleet could be grounded for as much as year.
I also read something disturbing: the engineering for the 787 was not done in-house, but outsourced all around. In that case, I would like to know who designed the battery pack and how they justify the heat build up problem.
I would also like to remind you young folks about the DC-10 problems when it was first flown in the early 70's. It suffered mucho problems, including:
**improperly designed engine pylons that caused a crash and 200+ deaths
**control computers that froze and did not have an “off” switch
**cargo bay latch too weak (leading to a humorous news story about a homeowner whose rose bushes were strewn with very expensive and very sexy lingerie from an over-passing DC-10 whose latch failed and scattered passenger luggage all over the place on the ground)
Based on my experience, it is entirely possible that there has been a serious engineering failure and that the 787 is, quite simply, a lemon.
The DC-10 was designed by McDonnell-Douglas, whose engineers outright cheated in the wide-body's design, and this company is now a part of Boeing...
