SEATTLE - Boeing Co said on Tuesday it would cut its 787 production rate as it works through a new production-related structural defect in its troubled twin-aisle airliner program.
The company now forecasts delivering fewer than half of the lingering 100 or so 787s in its inventory this year - instead of the "vast majority" it had expected - as it continues forensic inspections and costly repairs to address quality flaws in the aircraft.
Boeing did not disclose a new production rate for the 787 program, but said it would shift temporarily below the current rate of five jets per month.
For the year so far, the company has delivered 156 jets of all types, compared with 157 for all of 2020, it said.
The latest new issue, first reported by Reuters on Monday, involved gaps where components are joined together in a forward pressure bulkhead, the U.S. Federal Aviation Administration said.
The FAA said late on Monday that Boeing, which spotted the problem, would fix it before the planes are delivered.
The U.S. planemaker's 737 MAX and 787 have been afflicted by electrical defects and other issues since late last year, and it only resumed deliveries of the 787 in March after a five-month hiatus.
"We will continue to take the necessary time to ensure Boeing airplanes meet the highest quality prior to delivery," Boeing said.
In June, Boeing booked 146 jet orders. That net figure takes into account instances in which the buyer converted an order to another model or canceled it entirely, including 71 737 MAX jets, the company said.
Its backlog increased from 4,121 to 4,166 aircraft, Boeing said.
Boeing handed over 45 planes to customers in June, its highest monthly total since March 2019, when the second of two fatal 737 MAX crashes occurred.
Its June delivery tally includes 10 widebody aircraft, one of which was a 787-9 for Turkish Airlines, Boeing said.
It also delivered 35 737s, including 33 737 MAXs and two P-8 maritime patrol aircraft to the U.S. Navy.
