Boeing shares fell more than 3% in early trading,as cutting 787 Dreamliner production target after new flaw found.

Boeing cut its delivery target for its undelivered 787 Dreamliner planes and said it will temporarily lower production rates after a new defect was detected on some of the wide-body jets.

Boeing said Tuesday it will deliver fewer than half of the Dreamliners it has already produced but has not yet delivered to customers.

CEO Dave Calhoun said at an investor conference last month that the company would deliver the "lion's share" of the roughly 100 Dreamliners in its inventory this year.

Boeing halted deliveries of the wide-body planes in May for thesecond timein less than a year as the Federal Aviation Administration reviewed the manufacturer's method for evaluating the aircraft. Last year, Boeing first disclosed incorrect spacing in some parts of certain 787 aircraft, including the fuselage, halting deliveries for five months.

The FAA said Monday the latest issue was related to that and was detected "near the nose" of certain 787 Dreamliners that Boeing has manufactured but not delivered.

Because most of an aircraft's price is paid when the plane is handed over to customers, further delivery delays would mean more financial strain for Boeing. The company is trying to regain its footing in the wake of the coronavirus pandemic and two fatal crashes that grounded its best-selling 737 Max .

"This issue was discovered as part of the ongoing system-wide inspection of Boeing's 787 shimming processes required by the FAA," the agency said. "Although the issue poses no immediate threat to flight safety, Boeing has committed to fix these airplanes before resuming deliveries."

Boeing said it would reduce production to fewer than the current rate of five planes a month for a few weeks but declined to say by how much. Boeing will reassign staff on the production line to inspect planes and make any necessary repairs.

"Based on data, the FAA will determine whether similar modifications should be made on 787s already in commercial service," the FAA said.

Boeing also said Tuesday it delivered 45 planes last month, 33 of them 737 Maxes. In the first half of the year the company handed over 156 planes, one fewer than its total for all of 2020, when coronavirus devastated the industry.

Net orders for the month totaled 146 planes, while gross orders of 219 were the highest in two years.

Those included an order for 200 Maxes toUnited Airlines, which the carrier announcedlast monthalong with an order for 70 Airbus narrow-body planes.
