American aircraft manufacturer Boeing has asked airlines that own the 737 MAX, its flagship plane, to carry out checks because of a risk of “loose bolt” on the rudder control system, the United States Civil Aviation Agency (FAA) announced Thursday.

The FAA said in a statement that it is closely monitoring targeted inspections of Boeing 737 MAX aircraft for the possibility of a loose bolt in the rudder control system.

After discussions between this agency and the manufacturer, the latter issued a multi-operator message (MOM) so that the airlines could carry out checks.

The problem identified on a particular aircraft has been resolved. Out of an abundance of caution, we recommend that operators inspect their 737 MAX aircraft and report their findings to us.

This inspection consists of opening an access hatch and visually observing whether everything is compliant. This process should take approximately two hours by air.

The FAA also asked airlines to report if this problem has been spotted in the past during maintenance operations.

She explained that Boeing had acted after an international operator discovered a bolt without its nut when carrying out a routine maintenance operation on the rudder control system mechanism.

The aircraft manufacturer then spotted a nut on an aircraft not yet delivered that 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.

More recently, the aircraft manufacturer had to slow down its deliveries due to problems on the fuselage, in particular on the rear bulkhead of the aircraft.
