Seattle - Boeing seems to have the problems with its suppliers under control. The American manufacturer delivered 61 aircraft from the Boeing 737 family last month.

The manufacturer has been in trouble in recent months by delays in the delivery of parts from Spirit AeroSystems (hulls) and CFM International (engines). In July Boeing could only have been able to deliver 29 single-aisle.

In August, that number rose to 48 aircraft for its best selling model. In September, there were thirteen more, according to the recent report published by the manufacturer.

Boeing increased its 737 production rate from 47 to 52 aircraft per month in June. But due to the delays in the delivery of parts from its main suppliers, many unfinished 737s were parked around the Renton factory. Boeing seems now to catch its targeted delivery pace from September.

In the third quarter of the year, Boeing delivered a total of 190 airplanes of which138 are from the 737 series and 52 are widebody aircraft (34 787, 12 777, 4 767 and two 747-8).

For the first nine months of 2018, 568 aircraft left the Boeing plants in Renton, Everett and North Charleston. The 737 series became by far the best selling model with 407 units, followed by the 787 Dreamliner family with106 copies.
