BOEING has told 737 Max 'operators to [adhere] to existing flight crew procedures to address circumstances where there's erroneous input from an AOA [angle of attack] sensor,' according to a statement from the US plane maker
(In fluid dynamics, angle of attack [AOA] is the angle between a reference line on a body (often the chord line of an airfoil and the vector representing the relative motion between the body and the fluid through which it is moving.)
The manufacturer's advisory comes after a 737 Max crashed off the coast of Indonesia that left 189 dead.
The sensor is intended to maintain air flow over a plane's wings but if it malfunctions it can cause the plane's computers to erroneously think it is in a aerodynamic stall - which can then cause aircraft to abruptly dive.
Bloomberg News earlier reported that the plane manufacturer was alerting airlines that faulty readings from a flight-monitoring system can cause the planes to abruptly dive.
The Lion Air 737 Max 8 jetliner dove into the Java Sea on Oct. 29 minutes after takeoff, nosing downward so suddenly that it may have hit speeds of 600 miles an hour before slamming into the water.
Moments earlier, the pilots radioed a request to return to Jakarta to land, but never turned back, according to Indonesia's National Transportation Safety Committee and flight-track data. The committee said they were dealing with an erroneous airspeed indication.
The Federal Aviation Administration (F) issued issued a statement saying it plans to issue an airworthiness directive on the issue and 'will take further appropriate actions depending on the results of the investigation.'
The F also notified other regulatory agencies around the world, which typically follow the US agency's lead on safety matters.
