The US Federal Aviation Administration (FAA) has grounded a number of Boeing 737 MAX 9 aircraft after the plane landed at Portland Airport with a torn emergency exit. On the night of January 5-6, a Boeing 737 Max 9 plane made an emergency landing in the US state of Oregon after part of its body, including a window, fell off in the air. The fuselage incident occurred at an altitude of about five kilometers. There were 177 passengers and crew members on board the damaged aircraft. According to representatives of the operating company Alaska Airlines, none of them were injured. Airline officials said after the incident that they had “temporarily” grounded all 65 of their Boeing 737 Max 9 aircraft to conduct inspections. The FAA’s decision will affect 171 aircraft. The European Aviation Safety Agency noted that no airline in an EU member state currently operates such aircraft. The UK’s aviation regulator said it will require all airlines operating Boeing 737 MAX 9 aircraft to comply with FAA regulations before entering UK airspace. The Turkish airline Turkish Airlines announced the suspension of operation of five Boeing 737 MAX 9 aircraft for inspections. What problems have you encountered with an airliner before? The first flight of the Boeing 737 MAX took place in 2017. After this, in the fall of 2018, an Indonesian airline Lion Air plane crashed into the sea, and in March of the following year, an Ethiopian Airlines airliner crashed. In both cases, problems were identified with the MCAS software. After the second crash, Boeing suspended operation of this aircraft model. The ban on Boeing 737 Max flights began to be lifted in December 2020. It has since shown an “excellent safety record”, according to British aviation expert John Strickland. However, last month the US Federal Aviation Administration (FAA) urged airlines to inspect Max models for possible loose bolts in rudder systems. The company discovered two cases of malfunction. In the first case, the bolt was missing a nut, and this was discovered by one of the operators during routine maintenance. In the second case, on an aircraft not yet in service, a nut was not tightened correctly. There have been no other 737 MAX incidents caused by possible loose equipment, but out of an abundance of caution, Boeing has advised operators to inspect all 1,370 737 MAX aircraft delivered worldwide.
