The condition can even lead to "excessive nose-down attitude, significant altitude loss, and possible impact with terrain", the official noted.
Boeing's bulletin was the first indication that an error with the aircraft's systems may have caused problems for the Lion Air flight, which took off from Jakarta.
In a statement, the FAA said that it would soon issue an airworthiness directive that will compel all airlines to follow an Operations Manual Bulletin Boeing announced on Tuesday, according to Bloomberg, which obtained a copy of the statement.
Indonesian investigators said Wednesday that an AOA sensor on the jet was replaced the day before the doomed flight, on October 28, when a pilot flying the same aircraft on a different route, from Bali to Jakarta, reported problems with it.
United said: "We are in receipt of a Flight Crew Operations Manual Bulletin, issued by Boeing, which applies to the 16 737 Max 8 aircraft now in our fleet".
On November 6, Boeing said it had 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. It wasn't immediately clear if it plans an update, though comments from Indonesian officials indicate they expect one. One of the pilots had trimmed the plane to push the nose down while trying to climb after aborting a landing, the report said.More news: Turkish cross-border fire kills four YPG members in Syria
For a safe climb-out, the aircraft's nose is pitched up at a small angle.
This comes in the wake of a new Lion Air Boeing 737 MAX crashing into the sea not long after leaving Jakarta, Indonesia, and killing all 189 passengers on board. Indonesian officials say that all 11 such aircraft have been tested and declared safe to fly. Boeing has been working to increase production capacity at the Renton, Wash., factory where 737s are assembled.
The Seattle Times reported in August that Boeing's Renton factory has struggled to meet its production targets amid late deliveries from companies manufacturing its components.
Attempts to fix the issues were unsuccessful, NTSC chairman Soerjanto Tjahjono has said, with the pilots of the 737's second-to-last flight experiencing conflicting information despite an AOA sensor being replaced.
Divers have recovered one of the two "black boxes" - the flight data recorder - but are still searching for the cockpit voice recorder, in the hope that it will shed more light on the cause of the disaster. If the AOA is too low, the aircraft won't climb out fast enough. "This bulletin reiterates existing, well-established procedures for 737 Max 8 pilots".
"We're going to learn from this just like we learned from the A330", he said, referring to a 2009 incident in which an Airbus A330 crashed off the coast of Brazil with 228 people on board due to electronics failures.
Some modern aircraft have systems created to correct the posture of the aircraft automatically to keep flying safely.
