The comments shed further light on the areas under scrutiny as investigators prepare to publish their preliminary report on November 28 or 29, one month after the Lion Air Boeing 737 MAX dived into the Java Sea, killing all 189 on board. "The bulletin is not re-affirming, it's enlightening and adding new info". The companies and the pilots should have been informed. On Tuesday, the aircraft manufacturer said it was focusing on cooperating with investigators. "Everyone on the 737 had to go through differences training for the MAX and it was never mentioned there either".
Boeing did not respond to requests for comment outside regular business hours.
But, according to the pilots union for American Airlines, the system upgrade wasn't included in Boeing's standard operating manual.
This device can then force the plane downwards to avoid a stall, but to such a degree that pilots can't pull the aircraft back level.
Boeing "also trails on deliveries of its high-margin MAX aircraft, which affect profit disproportionately, with the plane accounting for 37% of the total vs. guidance of 40-45%", Ferguson says.
Indonesian investigators have called for all 737 MAX pilots to undergo additional training, while the Federal Aviation Administration (FAA) and Boeing will determine if the aircraft should be subject to software and design improvements.
Ms Syari's tribute comes as Boeing has been accused of not warning airline pilots of a new feature on its 737 MAX jets which may have contributed to Lion Air flight 610's tragic crash. "Safety remains our top priority and is a core value for everyone at Boeing".

He said the USA pays billions "protecting other countries, and we get nothing but Trade Deficits and Losses". BEARDSLEY: As Macron spoke, Trump sat stony-faced, or one French newspaper put it, pouting and indifferent.
Boeing may be confident but that does not mean that regulators or airlines are.
Other major customers for the 737 MAX include FlyDubai with 7 in operation out of an order of 251, Jet Airways with a fleet of 5 out of a total of 220 on order and Lion Air who had received 13 of their order of 201.
This is because pilots' working environment and philosophy remain unchanged, he said, adding that the 737-MAX had only two sensors and not three, like its rival Airbus A320.
In a Boeing bulletin about the Lion Air crash, they spoke about the system created to prevent a plane stalling, and said it could make the plane dive if bad data was provided - they warned pilots about an "erroneous input" from the sensor.
The oversight has since been corrected by Boeing - but not in time to potentially help the pilots of the ill-fated Lion Air flight.
Boeing told airlines in a briefing around a week after the crash that this situation, where the AOA sensor pushed the plane down, could end in a crash, an aviation safety expert with knowledge of the briefing told The Wall Street Journal. According to Boeing, pilots could override the automatic response with a press of two buttons in the event of a system malfunction.
Investigators are still searching for the cockpit recorder from the flight, which they hope will help them understand what caused the plane to crash.
