Calhoun said, adding that the
board had trusted Mr. Muilen-
burg and his proven record of
taking risks that had paid off.
Mr. Muilenburg couldn’t be
reached for comment.
Mr. Calhoun publicly ex-
pressed support for Mr.
Muilenburg in the months lead-
ing up to his removal in De-
cember, but the board eventu-
ally became frustrated with Mr.
Muilenburg’s overly optimistic
projections and convinced that
he had mismanaged the com-
pany’s relationship with the
FAA, potentially complicating
the plane’s return to service,
people familiar with the matter
have said.
Mr. Calhoun had become
more engaged in managing the
company after being made
chairman in October, when the
board stripped Mr. Muilenburg
of that role, but has sought to
draw a clean break from the
company’s past missteps.
“I watched the same movie
you did—I think I was in the
front-row seat, and I might
come to exactly the same con-
clusions you do,” Mr. Calhoun
said in a call with reporters in
January. “My leadership role
here at Boeing is intended to
make changes that correct a lot
of those situations.”
A Boeing spokesman said
Mr. Calhoun wanted to provide
Boeing executives with more
company for installing unap-
proved sensors on hundreds of
planes, including some MAX
jets. A Boeing spokesman said
the company has done a thor-
ough internal review and im-
plemented changes to address
the FAA’s concerns.
Mr. Calhoun told the New
York Times that the challenges
he is facing are more than he’d
anticipated, according to the
March 5 article. “And it speaks
to the weaknesses of our lead-
ership,” he said.
He said Mr. Muilenburg may
have increased production of
the 737 MAX too quickly at the
expense of quality. Mr. Calhoun
suggested that Mr. Muilenburg
had been chasing a higher
share price, according to the
article.
“I’ll never be able to judge
what motivated Dennis,
whether it was a stock price
that was going to continue to
go up and up, or whether it
was just beating the other guy
to the next rate increase,” Mr.
CEO Dave
Calhoun has
said he will
focus on
rebuilding
trust in the
company.
context about what he had said
in the interview.
“It is important to Dave that
his teammates have a full un-
derstanding of his views and
the context they were given
in,” a Boeing spokesman said.
“And like many interviews, not
everything makes it into the
story, and Dave wanted to
share some of the points he
made about the good work of
our team and the strength of
our portfolio of products and
services.”
In the message on Friday,
Mr. Calhoun said he had
wanted to speak candidly about
the company’s challenges, but
hadn’t intended to undermine
its current leadership team.
He said he was invested in
Mr. Muilenburg’s success, and
that the disappointments he
discussed in the interview
mostly related to the com-
pany’s failure to return the
plane to service going into the
fourth quarter.
“Now is not the time to look
behind us. I regret doing it.
Now is the time to look for-
ward and build on our founda-
tion,” he wrote.
Mr. Calhoun said he main-
tained his commitment to be-
ing more transparent.
“I have said that transpar-
ency is a messy process but
worth it in the end, and I still
believe it.”
flights needed to vet fixes to
MAX flight-control software
and move forward with certi-
fying the grounded jets as
safe to carry passengers
again.
Complications stemming
from mandatory wiring
changes could delay FAA di-
rectives ungrounding the be-
leaguered fleet for at least
several weeks, some of the
people said, potentially be-
yond the mid-June timeline
previously projected by in-
dustry and government offi-
cials.
The wiring concerns also
have turned into a test case
of what Dave Calhoun, Boe-
ing’s new chief executive, has
touted as his more realistic
and conciliatory approach to-
ward FAA safety demands be-
fore allowing the MAX fleet
back in the air.
The FAA said on Sunday
that it continues to engage
with Boeing on the wiring is-
sue and the MAX will return
to service only after the FAA
is satisfied that all safety-re-
lated issues are addressed.
A Boeing spokesman said
that discussions with the FAA
continue, but regardless of
the outcome the company’s
estimate for a midyear return
to service is unchanged.
If Boeing continues to
press its case in the face of
the FAA’s preliminary deci-
sion, one of the people
briefed on the deliberations
said, the likely upshot would
be months of additional de-
bate involving the FAA and
foreign regulators in Europe,
Canada and Brazil.
That is a major reason
Boeing, which already has
been devising ways to relo-
cate certain wiring, ultimately
is likely to accept the FAA’s
position. And from a public-
perception standpoint, the
people said, U.S. authorities
are loath to break with de-
mands from foreign regula-
tors that wiring fixes must be
completed before the fleet is
allowed to resume operations.

On Wiring
PG&E said its inspections
have uncovered the need to re-
place thousands of hooks and
other hardware showing wear
or corrosion and that all of the
highest-priority problems have
been addressed.
The hooks, about the width
of a fist, hang from the steel
towers that support transmis-
sion lines, helping to hold the
charged wires.
Windy conditions, over de-
cades, can cause the hooks to
rub against their hangers,
which can erode the metal and
increase the odds of failure.
State investigators said they
believed about 75% to 80% of
the hook that caused the Camp
Fire had worn away before it
broke.
PG&E has a poor record of
maintaining its transmission
lines and steel towers, a Wall
Street Journal investigation
last year found.
PG&E internal documents
show that it knew for years
that many of its transmission
towers had reached the end of
their useful lives, the Journal
reported last year.
In a 2017 internal presenta-
tion, the utility estimated that
its transmission towers were
an average of 68 years old.
Their mean life expectancy
was 65 years. The oldest steel
towers were 108 years old.
Plagued by shoddy records
and aging equipment, the com-
pany struggled to respond this
past decade as drought and
climate change made a tinder-
box of its service territory and
exposed the dangers of its
power grid.
Its equipment sparked 18
deadly wildfires in 2017 and
2018, killing more than 100
people, state investigators say.
The company has agreed to
a settlement with state regula-
tors probing the cause of the
Camp Fire after they found
systemic problems with its in-
spection and maintenance
practices.
The hook that failed in No-
vember 2018 was manufac-
tured by Ohio Brass Co., a
company that originally made
metal harnesses for horse-
drawn buggies before develop-
ing hardware for some of the
first transmission lines ever
built, according to court fil-
ings, historical documents and
Mr. Ramsey.
A spokesman for Hubbell
Inc., which purchased Ohio
Brass in 1978, said the com-
pany was “unable to identify
the manufacturer of the hook
in question.”
Photographs of hooks re-
moved from the tower on the
transmission line where the
fire started show Ohio Brass
markings.
Ohio Brass catalogs from
that period reviewed by the
Journal don’t describe any
warranties, and there is no ev-
idence that metal hooks manu-
factured around 1918 were ex-
pected to last a century.
“I can tell you positively
they had no idea” how long
they would last, said Doru Ste-
fanescu, a professor emeritus
of materials science at Ohio
State University who is an ex-
pert in the kind of malleable
iron used to make the hooks.
Even today, he said, “we don’t
have data to tell you what hap-
pens over 100 years.”
Court papers filed by attor-
neys representing fire victims
suing PG&E for damages de-
scribe the hooks as “all worn,
rusted, and degraded.” PG&E
inspectors, two months after
the fire, noted in an inspection
that a hook on the tower
where the fire started “is rusty
and corrosion is set on.”
The line that sparked the
Camp Fire, the Caribou-Pa-
lermo, is part of a transmis-
sion network known as the
Caribou-Valona system, built

around 1921 to carry hydro-
electric power from the Sierra
Nevada mountains to the Bay
Area. Hundreds of its original
steel towers are still in use.
PG&E has said in recent
court filings it didn’t track
when its hooks were installed
or how long they had been ex-
posed to weather. It also didn’t
routinely inspect them to look
for corrosion or wear. Before
the Camp Fire, PG&E inspec-
tion forms didn’t even include
space to note the condition of
hooks and other hardware.
There were reasons to be
concerned about the condition
of these hooks, records show.
In 1924, Ohio Brass stopped
selling the type of malleable
iron hooks that design docu-
ments indicate were used on
the Caribou-Palermo just a few
years earlier. Ohio Brass,
switched to a new manufactur-
ing method that produced iron
“freed from all tendency to-
ward embrittlement when hot-
dip galvanized,” according to
an article in the March 1926
edition of the Journal of the
American Institute of Electri-
cal Engineers.
In 1987, PG&E engineers no-
ticed worn hooks on the
southern portion of the 1921
transmission system. They re-
quested tests on two hooks,
which were supposed to hold
up to 30,000 pounds. Both
failed at 11,500 pounds. They
then tested a third hook that
didn’t have any signs of wear.
It failed at 6,900 pounds. One
of the hooks was made by
Ohio Brass while another was
made by a different company,
Lindsey Manufacturing Co., ac-
cording to PG&E records.
The report concluded that
PG&E should test more hooks
to determine whether they
were still dependable. In De-
cember, PG&E said in court fil-
ings it couldn’t find any re-
cords related to further
testing.
PG&E didn’t routinely climb
its transmission towers before
the Camp Fire, instead in-
specting them by ground or by
air every five years. Since the
Camp Fire, PG&E has rushed
to inspect its entire electrical
grid in search of other poten-
tially dangerous problems. In-
spectors last year spotted
more than 5,000 high-priority
safety hazards that hadn’t
been previously discovered.
Judge Alsup recently ques-
tioned PG&E’s new inspection
procedures after an expert
hired by victims’ attorneys
testified that he spotted a
worn hook on the Cresta-Rio
Oso transmission line, which
was built parallel to the Cari-
bou-Palermo around 1928. The
hook was a couple of hundred
feet from the tower where the
Camp Fire started.
Scott Hylton, a former Sac-
ramento utility lineman, testi-
fied that after he first spotted
the hook in the weeks follow-
ing the fire, he assumed PG&E
workers would replace it dur-
ing inspections. When it was
still there a year later, “I felt
an obligation to bring it for-
ward to make sure it wasn’t
missed,” he said.
PG&E inspectors had exam-
ined this tower twice last year,
once by climbing it and once
by drone. In court filings, the
company said inspectors failed
to spot the hook damage based
on the photos they took. After
looking again, they determined
the hook was about 30% worn.
PG&E’s guidelines require it to
replace hooks with 30% to 50%
wear within a year—or within
six months if they are in fire-
prone areas.
“If I had C-hooks that were
30% worn out, I’d replace
them,” Mr. Hylton said in
court.

Boeing Chief Executive Dave
Calhoun told executives that he
regretted voicing criticisms of
the company’s leadership and
former CEO in a recent inter-
view with the New York Times.
Mr. Calhoun, who started as
CEO in January, is dealing with
the fallout of his candid assess-
ment of Boeing’s problems,
telling executives they have his
support despite sometimes
harsh comments published in
the article.
“I am both embarrassed and
regretful about the article,” Mr.
Calhoun wrote in a message
addressed to Boeing senior
leaders, reviewed by The Wall
Street Journal. “It suggests I
broke my promise to former
CEO Dennis Muilenburg, the
executive team and our people
that I would have their back
when it counted most. I want
to reassure you that my prom-
ise remains intact.”
Mr. Calhoun, who served on
Boeing’s board for about a de-
cade before being appointed
CEO, had vowed to make a
fresh start for the beleaguered
company. He has said he
planned to focus on rebuilding
trust in the company and being
more transparent.
Boeing has been in crisis
since two of its 737 MAX planes
crashed within a five-month pe-
riod, killing 346 people. The
MAX has been grounded world-
wide since last March and Boe-
ing had to shut down produc-
tion of the plane this year. The
crashes have drawn scrutiny of
the plane maker’s engineering
culture and damaged the com-
pany’s relationships with suppli-
ers, customers and regulators.
In a preliminary report re-
leased Friday, House investiga-
tors said production pressures,
faulty assumptions, and a “cul-
ture of concealment,” com-
bined with insufficient federal
safety oversight, led to the two
crashes.
Separately, in Boeing’s latest
reported production lapse, the
Federal Aviation Administra-
tion on Friday proposed a $19.7
million penalty against the
