US aircraft giant Boeing has warned that it faces spiraling costs and plummeting revenue after the global grounding of its 737 Max passenger jets. The airline is keen to return the aircraft to service in the autumn.
Boeing has said it faces a financial hit over the 737 Max crisis of some $6.6 billion (€5.7 billion), fueling profitability pressures.
The passenger jets have been grounded since March after two crashes that killed 346 people, in which software glitches appeared to have played a role.
The airplane manufacturer announced Thursday that its second-quarter earnings for the year would be reduced by $4.9 billion as it compensated airlines for disruptions and plane delivery delays. That figure omits any amounts Boeing may need to pay in the future to compensate families of the victims.
The aircraft manufacturer is still working on flight-control software to iron out suspected problems. The company said it was hoping to receive regulatory approval to return the Max series to service later this year.
