U.S. airplane manufacturer Boeing announced Tuesday that it had only delivered 26 planes in September, down 70% from a year earlier. European competitor Airbus reportedly delivered 71 planes last month.

In the first nine months of the year, Boeing delivered 302 planes, in comparison to Airbus' 571.

Boeing's business has struggled due to 737 Max model crashes in Ethiopia in March and Indonesia in October 2018. The crashes resulted in 346 deaths.

The Boeing 737 Max has been grounded since March, as the company deals with regulators to put the plane back into the air. European safety regulators and the U.S. Federal Aviation Administration have not agreed on some of the 737 Max's safety revisions such as its reconfigured flight-control computers.

Boeing announced in September it would pay approximately $144,500 to each family affected by the 737 Max crashes. Boeing has set up a $100 million assistance fund for the victims in the wake of the tragedies.

In the second quarter of 2019, Boeing reported a loss of $2.9 billion, the company's worst financial performance ever.
