The Directorate General of Civil Aviation (DGCA) has issued an advisory to all airlines operating the Boeing 737 aircraft and instructed them to address concerns raised in a United States (US) investigation report over the 'potential risk' of a malfunction of the 'rudder control system'. The rudder system controls the flight on vertical axis.

The civil aviation regulator's safety recommendations come in light of a US National Transportation Safety Board (NTSB) Aviation Investigation Report that highlighted safety concerns in Boeing 737 aircraft equipped with a certain type of rudder control system.
