The Globe and Mail reports in its Saturday edition that cracks are appearing in the cozy Boeing-Airbus world with new speculation that Commercial Aircraft Corp. of China, known as Comac, is in an increasingly strong position to be a disruptor. The Globe's Gus Carlson writes that the company is aggressively marketing its 200-seat C919 narrow-body airliner, which went into service a year ago. The rise of Comac should be a good thing; it may not be. The Comac alternative is a case of buyer beware. So many of Comac's strong points are also red flags. Yes, the company has the financial heft to break into an industry that has enormously high barriers to entry, but its financial strength comes from the communist Chinese government. Trust in Beijing is already low around the world. In 2021, the U.S. prohibited American investing in Comac because of its ownership structure. The questions raised by Comac's DNA are real: How closely is the government monitoring quality control? In the event of a quality-related air disaster involving a Comac plane, can the Chinese government be relied upon to apply proper accountability standards that improve manufacturing practices? If not, what recourse do the airlines and their customers have?
