American aircraft manufacturer Boeing's problematic recent history is also weighing on its major customer from the United Arab Emirates, the airline Emirates. The chairman is now calling for stricter measures in an interview with CNBC.

The bolt problems that led to an aircraft door blowing off the fuselage of a Boeing 737 Max 9 during flight in January have raised serious new concerns for the company, which has 245 passenger planes on order. The total share of Boeing's order book makes it clear that Emirates is the largest customer of all.

”"We are not at all happy with what is happening and have always taken for granted that this aircraft will be included in the fleet as promised. Now we have delays, and it is not up to us," chairman and CEO Sheikh Ahmed bin Saeed al Maktoum told CNBC.

Boeing's safety crisis is not a new problem, however. The attention began during a period in late 2018 and early 2019 when two planes of the predecessor model Max 8 crashed due to insufficient training of pilots on a new autopilot system. 346 people died as a result of the manufacturer's safety deficiencies, which were found in investigations conducted by the US Federal Aviation Administration (FAA). Safety protocols had not been followed.

When the same thing was discovered after the door flew off during an Alaska Air flight in January, a new crisis erupted at Boeing, which has now announced changes in both management and the boardroom.

However, Emirates chief Ahmed bin Saeed al Maktoum does not want to go so far as to terminate contracts with Boeing and instead rely on deliveries from European arch-rival Airbus.

”"Shut up and get the job done, I want to tell them, and I think they can fix it," said the Emirates boss.

Boeing shares fell 1.1 percent in early trading on Wall Street.
