January 3, 2019, © Leeham News.: The last year was a quiet year for the airliner side of Irkut Corporation (Irkut). It continued testing its two MC-21 single-aisle airliners and rolled out the third test aircraft.
Behind the scenes, there were larger changes. Irkut was handed the shares of Sukhoi Civil Aircraft Company (SCAC), the designer and producer of the Superjet 100. The move is part of merging the Russian airliner industry into one company.
During 2018, United Aircraft Corporation (UAC), the parent of Irkut and SCAC, started the consolidation by moving all new airliner projects to Irkut, including the CR929 widebody project with China. The consolidation will continue 2019.

Dec. 21, 2018, © Leeham News: It is a stretch to say 2019 is a pivotal year for Boeing.
There would have to be events of tsunami proportions to be pivotal for a company with revenues of more than $90bn.
But there is no doubt 2019 will be a very important year for Boeing.
Update to Outlook 2019: leaving Airbus’ troubled year behind.
Dec. 20, 2018, (c) Leeham News: The French newspaper Le Monde reported that Airbus may face billions of dollars in fines over the US probe into bribes and corruption.
The US probe is an outgrowth of the 2016 investigation begun in the UK and continental Europe over bribes and the use of third parties in sales of commercial and military aircraft. Airbus self-reported violations to authorities, triggering the investigations.
The US investigation began at the end of 2017.
According to the news article, Airbus could be banned for five year from civil and military contracts in the US.
In response, Airbus issued the following statement:

Dec. 17, 2018, © Leeham News: Lion Air’s co-founder is threatening to cancel an order for more than 200 Boeing 737 MAXes following what he says is Boeing’s blaming the airline for the Oct. 29 crash of Flight 610.
All 189 people aboard the three month old 737-8 died when the plane plunged into the Java Sea 11 minutes after take-off from Jakarta.
Calling a Boeing statement issued Nov. 27 a “betrayal,” co-founder Rusdi Kirana Dec. 3 threatened to cancel to big Boeing order. He amplified his remarks Dec. 11.
Dec. 17, 2018, © Leeham News: Airbus has joined with Georgia Institute of Technology to open a technical center for Model-Based Systems Engineering (MBSE) for Overall Aircraft Design (OAD).
The Georgia Tech Center opened in October.
It’s an expansion of the Airbus footprint in the growing US Southeast aerospace footprint.
It’s also a step in transforming Airbus’ design technology, an effort that’s been underway in cooperation with European universities and institutes. Read more
December 14, 2018, ©.Leeham News: Last week we introduced a horizontal stabilizer to make our DC-9 like aircraft stable in pitch. We got a pitch moment curve which was forcing the nose down of the aircraft if there was an increase in Angle of Attack (AoA) of the aircraft. Should the angle of attack decrease from a trimmed position, the aircraft would put the nose up to correct the disturbance. The aircraft is stable in pitch.
Now we take a closer look at how such a horizontal stabilizer is made and why.
