Bank of America: Because of its "monopoly position", Boeing will have limited impact from the "door falling incident"

"Due to the duopoly nature of the industry (Boeing and Airbus), we do not believe this will affect any orders for the 737 MAX aircraft." The door falling off incident on an Alaska Airlines Boeing passenger plane has caused damage to Boeing's reputation, but some Wall Street analysts are still downplaying the financial impact of the accident on Boeing.

Bank of America analysts said in a recent research note:

"Currently, due to the duopoly nature of the industry (Boeing and Airbus), we do not believe this will impact orders for any 737 MAX models. However, if similar issues continue to occur... at some point, travelers may lose confidence in the 737 MAX, and that could ultimately impact sales of the aircraft."

Bank of America analysts said the specific cause of the accident was not yet clear. Assembly errors by Boeing, improper installation by fuselage manufacturer Spirit AeroSystems, or other negligence may have led to the accident. But they pointed out that the aircraft was relatively new and was only delivered on October 31. They added that "some review responsibility must also remain with regulators as the FAA certifies the safety of these aircraft before they are delivered".

Analysts at investment bank William Blair also said they did not expect a major hit to Boeing's financial position. They said in Monday's report:

"While the Alaska Airlines door incident is horrific, we do not believe it will have a significant financial impact on Boeing unless another incident occurs after the aircraft is returned to service."

William Blair analysts estimate that 737 Max9 deliveries accounted for less than a fifth of Boeing's total deliveries over the past two months.

According to FactSet, a financial data service provider, of the 23 analysts who have rated Boeing stock, 18 have a buy rating or equivalent rating.

It is worth mentioning that U.S. regulatory agencies have issued grounding orders to airlines, and 171 737 MAX9s have been grounded worldwide. Many airlines from the United States, Panama to Turkey have grounded this model for inspection.
