Boeing advised airlines to evaluate their B737 Max fleet after an international operator found a bolt with a missing nut during normal maintenance.

The issue was fixed on December 29, and Indian airlines Akasa Air, SpiceJet, and Air India Express operate B737 Max planes.

The FAA is monitoring "targeted inspection" of Boeing 737 Max planes for a possible loose bolt in the rudder control system.

The incident, according to Akasa Air, did not have any effect on the operating fleet of the firm or on the delivery of aircraft.

 The FAA issued a Multi-Operator Message (MOM) advising operators of modern single-aisle aeroplanes to check rudder tie rods for loose hardware in collaboration with it.

The agency wants airlines to use their certified safety management systems to check for loose hardware and inform them how quickly these two-hour inspections can be performed.

The FAA will assess the possibility of taking further measures in response to any further findings of loose or absent hardware.

Boeing is in the final weeks of contract talks with 22,000 engineers testing its new commercial-aircraft chief, potentially impacting its cost reduction efforts.
