Boeing Offered Crucial Warning Light as Optional Add-On for 737 Max

Boeing admits it knew of flaw in 737 MAX planes before fatal crash

Industry and government officials, cited by The Wall Street Journal, said that Chicago-based Boeing Co. knew that there was a problem with the cockpit safety alert on 737 MAX jets for a year before one of them crashed in Indonesia in October 2018.

The safety alert, called an "angle of attack" (AOA) indicator, tells pilots if a sensor is transmitting bad data.

Boeing said the 737 MAX's "display system software did not correctly meet the AOA Disagree alert requirements", adding that "software delivered to Boeing linked the AOA Disagree alert to the AOA indicator, which is an optional feature on the MAX" and earlier versions of the 737.

Immediately following the company's reiteration that it did not merit action in 2017, Boeing confirmed that it was brought up again in 2018 and a Safety Review Board (SRB) was convened to "consider again whether the absence of the [safety] alert from certain 737 Max flight displays presented a safety issue".

The manufacturer's own experts reviewed the issue and "determined that the absence of the AOA Disagree alert did not adversely impact airplane safety or operation", according to the Boeing statement.

But the plane-maker didn't share its findings with airlines or the Federal Aviation Administration until after a Lion Air plane went down off the coast of Indonesia in October, according to a Boeing statement on Sunday as it provided additional details of an issue that first came to light last week.

Boeing's 737 MAX 8 has been involved in two deadly crashes in less than six months, killing a combined 346 people. Boeing's disclosure on Sunday, however, raised fresh questions about the company's candor with regulators and airline customers.

Tesla raising $2.3 billion after money-losing first quarter
If all the options are exercised, the gross proceeds would come to about $2.3 billion before discounts and expenses, Tesla said. When first announced, shares in the company fell briefly but quickly rose once details of the plan became known.

"However, Boeing's timely or earlier communication with [airlines] would have helped to reduce or eliminate possible confusion", the spokesman said in a emailed statement emailed to Associated Press.

Marking a departure from that stand, a new statement said the company had spotted the problem but chose to act on it under a longer timeline.

Neither the Lion Air aircraft nor the Ethiopian Airlines jet had the feature. The Review Board determined the issue to be "low risk" and would be required to be a part of Boeing's overall enhancement announced after the Lion Air. But the disagree alert could have notified pilots that a sensor was malfunctioning. The alert was supposed to flash when two angle-of-attack vanes sent conflicting data about the relation of the plane's nose to the oncoming air stream.

"That's negligence from Boeing in regards the AOA system", said Evi Samsul Komar, whose son and nephew were on the fatal flight.

Nevertheless, it did not reportedly provide some carriers and pilots with consistent explanations even after the first tragedy and became "more forthcoming" with airlines only after the second 737 MAX crashed in Ethiopia.

But the new jets were already being delivered, and United States regulators were not immediately told as Boeing did not believe the apparent mistake posed any risk. This system automatically pitched the plane downwards to prevent stalls, an unfortunate byproduct of the 737 MAX's aerodynamic design and high-mounted engines.
