Boeing confirms 737 MAX timetable as profits tumble

grounding but said it still expects regulatory approval this year to return the plane to service.

The company booked an additional $900 million in costs due to the MAX as it reported much lower profits than analysts expected. The top-selling MAX has been grounded since mid-March following two deadly crashes.

However, shares advanced in pre-market trading after Boeing reiterated its timetable for MAX regulatory approval and said it expects to fully restore MAX production levels by late 2020.

"Our top priority remains the safe return to service of the 737 MAX and we're making steady progress," said Chief Executive Dennis Muilenburg.

Net income was $1.2 billion, down 50.6 percent from the year-ago period.

Revenues tumbled 20.5 percent to $20 billion, reflecting a hit from halted deliveries of the MAX. The aviation giant, which has been in crisis mode following two MAX crashes that killed 346 people, said it "has assumed that regulatory approval of the 737 MAX return to service begins in the fourth quarter of 2019."

The company, which trimmed its MAX production level, said it also expects to "gradually increase the 737 MAX production rate from 42 per month to 57 per month by late 2020."

Boeing has been in close contact with the Federal Aviation Administration and other global regulators on certification, which has dragged on for months beyond initial expectations.

Many analysts now expect the timeframe to be extended further following disclosures last week of text messages between two Boeing pilots in 2016 that raised questions about whether the company was aware of problems with a flight handling system that has been blamed for both crashes.

The company said it accounted for $900 million in additional costs due to MAX delays, lifting the total so far since the grounding to $9.3 billion.

The results came hours after Indonesian investigators briefed families of people killed in the Lion Air crash in October 2018. In a slide-show presentation, Indonesia's National Transportation Safety Committee told relatives their report would include problems with the Maneuvering Characteristics Augmentation System, a flight handling mechanism, as a "contributing factor."

A preliminary investigation of the deadly March 2019 Ethiopian Airlines crash has also pointed at the MCAS. Boeing's efforts to have the plane recertified have centered on upgrades to the MCAS.

Some analysts have called for Muilenburg's ouster following the accidents. He is scheduled to appear on Capitol Hill next week for the first time since the crashes.

On Tuesday, Boeing replaced commercial airplane chief Kevin McAllister, the most significant departure since the MAX crisis began.

Boeing also said it would trim its output of the 787 Dreamliner plane from the 14 planes per month currently to 12 beginning in late 2020 due to global trade uncertainties.

The company likewise pushed back the timeframe for the 777X, a long-range, wide-body plane, to early 2021 from late 2020. The plane's development has been slowed by issues with the engine, which is being developed by General Electric.

Boeing shares rose 1.7 percent to $342.67 in pre-market trading.
