IF one thing is clear after this week’s National Transportation Safety Board hearings on the certification of the Boeing 787’s lithium-ion battery, it is that the Federal Aviation Administration
and the industry it regulates share a cozy relationship that sometimes
takes a front seat to safety. This relationship contributed to the
grounding of the 787 Dreamliner in January and the astonishing swiftness with which the airplane was approved to return to commercial flight.
As a former chairman of the safety board, I know firsthand that
effective government oversight helps prevent fatal airplane accidents.
For decades, the F.A.A. has used what it calls “designated airworthiness
representatives” to certify that aircraft meet government safety
standards. They were experts selected and supervised by the agency, even
if they worked for the manufacturer. But in 2005, the F.A.A. changed
the process of selecting those designees, ruling that aircraft
manufacturers who qualified under the new procedures could choose their
own employees to certify their planes. The distinction is important,
because it suggests a slide toward industry self-certification.
This laissez-faire certification system would save the aviation industry
nearly $25 million between 2006 and 2015, the F.A.A. said at the time —
a pittance when compared with Boeing’s $81 billion in revenue for 2012.
It is no coincidence that the committee that helped develop this
process was made up of industry members. Essentially, aircraft makers
persuaded the F.A.A. to let them certify their own aircraft so they
could save money.
Problems with the plane’s lithium-ion batteries emerged about 14 months
after the 787 entered commercial service in November 2011, underscoring
the folly of this policy. As we learned from this week’s hearings, the
agency let Boeing help write the safety standards, develop the testing
protocol and then perform those tests. In 2008, a year after standards
for the battery system were approved with special conditions on the
containment and venting of the batteries, stricter industry guidelines
for these batteries were released. But the F.A.A. did not require the
787 to meet those new guidelines.
The potential for these batteries to catch fire was well known. In 2011,
one of these batteries on a jet built by Cessna started smoking. The
F.A.A. ordered Cessna to remove the batteries, and Cessna replaced them
with less combustible nickel-cadmium batteries. Incredibly, the F.A.A.
failed to absorb the lessons of this experience.
Boeing initially estimated that there was the potential for one battery
failure incident in 10 million flight hours. As it turned out, smoke and
fire broke out in batteries on two separate 787’s in just the first
52,000 flight hours. Even Boeing’s chief engineer on the 787, Mike
Sinnett, acknowledged to the N.T.S.B. that one of the battery tests had
been inadequate and was not “conservative enough.”
Now the 787 has been grounded for months, the F.A.A. has lost face, and
Boeing has been losing $50 million a week on a plane that was supposed
to demonstrate innovative aircraft design and help the United States
recapture its onetime dominance of the world aircraft market.
Given all of that, the F.A.A.’s recent decision to approve Boeing’s
plans to fix the lithium-ion battery seems shortsighted and represents a
complete failure of government oversight. It is puzzling that the
agency was so quick on its feet to accommodate Boeing in recertifying
the safety of the airplane, without even knowing the root cause of the
battery problem.
And where has Congress been? The first hearing on Capitol Hill on the
787 was held just one week ago. But some of the testimony was very
telling. The Government Accountability Office questioned the F.A.A.’s
ability to maintain the up-to-date knowledge necessary to approve new
equipment, and the Department of Transportation’s inspector general
criticized the agency for failing to ensure that personnel designated by
aircraft manufacturers to certify their aircraft or components were
competent to do so.
Congress needs to take a closer look at the F.A.A.’s practices and
procedures to make sure that safety is the top priority, and should
overhaul the agency to provide more direct government oversight as new
aviation technologies are introduced.
We enjoy the safest commercial aviation system in the world. But what
about tomorrow? After the N.T.S.B. hearings, this question is more
important than ever.
