Boeing 'disappointed' customers but is on the path to 'transformational change,' commercial jet CEO says

LONDON — Boeing's output of 737 Max planes is showing signs of improvement, the new head of its commercial unit said ahead of a major air show on Sunday, while admitting that the manufacturer has "disappointed" customers with delayed planes.

Boeing is trying to get past several safety and manufacturing crises, including the midair door plug blow out in January, which have slowed deliveries of planes to airlines and prompted the Federal Aviation Administration to increase its oversight of the storied manufacturer.

Stephanie Pope, in her first press conference since taking over the key role at the troubled aircraft manufacturer in March, reiterated that Boeing has committed to increasing production of the Max to 38 a month. Production slipped into the mid-20s per month in the first half of the year, analysts have said.

Pope said Boeing is on the right path to improving its manufacturing quality, safety and predictability of deliveries, a "transformational change" that she said will take years.

"It still doesn't take away the reality that we've disappointed" our customers, she said at a press conference before the Farnborough Airshow, outside of London. "We've impacted their business and we haven't met the commitments and lived up to being the partner that they expect and they need us to be."

Boeing has unveiled a host of goals aimed at getting it back on the right path, like improving worker training and manufacturing processes, among others. In the spring it delivered an improvement plan to the FAA that the agency ordered after the blowout in January.

"This plan is not a three month plan," said Pope. "I call it transformational because some of these actions will take years."
