The Lion Air Boeing 737 Max 8 plunged into the Java Sea last week, killing all 189 people on board.
An AOA - or angle of attack - sensor is a vane that sits outside of the aircraft and gives pilots a visual reading of the plane's angle of attack, or "the angle between the oncoming air or relative wind and a reference line on the airplane or wing", according to Boeing.
The FAA said that if the condition is not addressed, it could cause the flight crew to have difficulty controlling the plane, possibly with significant loss of altitude.
The Boeing statement comes amid a number of significant developments in the investigation into the fatal airline disaster, following the discovery of Flight 610's flight data recorder last Thursday. 737 MAX passenger plane slammed into the sea on October 29, only minutes after take-off from Jakarta, en route to Bangka Island near Sumatra.
In a statement released by Boeing on Tuesday it "issued an Operations Manual Bulletin (OMB) directing operators to existing flight crew procedures to address circumstances where there is erroneous input from an AOA sensor".More news: BOURKE STREET CHAOS: Car explodes, man with knife shot by police

A week after an Indonesian low-priced airline Lion Air plane crashed killing 189 people, another of its aircraft was involved in an incident on Thursday, when it smashed into a pole during takeoff from an airport on Sumatra Island.
The glitch had been repeatedly serviced and Lion Air's technical team declared the plane to be airworthy. Together, the two airlines have placed orders for more than 400 Boeing 737 MAX aircraft.
One of the critical ways a plane determines if a stall is imminent is the angle of attack measurement. The malfunction can cause the computers to erroneously detect a mid-flight stall in airflow, triggering a dive to regain speed to keep flying.
If there is an "uncommanded nose-down stabilizer trim" on the Max, pilots can counteract it by pushing a switch on their control yoke.
Jet Airways, which has at least five MAX planes in its fleet, said these planes continue to fly in compliance with the AD issued by the manufacturer and the regulatory authorities. In addition, a system known as pitch trim can be changed to prompt nose-up or nose-down movement. United Technologies supplies the angle-of-attack sensors and indicator for the 737 Max, according to Airframers.net. If pilots aren't careful, they can cause severe nose-down trim settings that make it impossible to level a plane.
