Serious accidents and technical difficulties

Boeing has experienced serious accidents and technical difficulties with its 737 MAX in recent years. In December, the manufacturer informed airlines that MAX aircraft needed to be inspected for loose parts in the rudder control system, following the discovery by an international operator of a bolt without a nut during a routine inspection. The aircraft manufacturer then spotted a nut on an aircraft not yet delivered “which was not properly tightened”.
The 737 MAX was grounded for many months around the world after two air disasters involving the aircraft in October 2018 and March 2019, which left 346 dead. The FAA had only authorized return to service after changes to the flight control system. More recently, Boeing had to slow down deliveries due to problems with the fuselage, particularly with the aircraft’s rear bulkhead.
