Boeing has taken a US$1 billion ($1.5b) hit in the wake of the 737 Max crashes and groundings and scrapped profit forecasts for the year.
The aerospace giant said profit fell by a fifth in the three months to March as the fallout from two crashes by the bestselling airliner weighed on results.
Abandoning its full-year financial forecasts as a consequence of the disruption, Boeing said the guidance "does not reflect the 737 Max impacts... due to the timing and conditions surrounding the return to service of the 737 Max fleet".
Revenue slipped 2 per cent to US$22.9b, but core operating profits fell just over a fifth to almost US$2b in the quarter.
Boeing's commercial aeroplanes -division - its biggest unit - reported a US$1.1b drop in revenues to US$11.8b. The company also booked US$1b of charges on the cost of building the 737 Max during the quarter, with production being cut by a fifth to 42 aircraft a month in the wake of the crashes.
