Boeing refused to fix 737 Max planes’ problems after Lion Air crash

Chicago, May 15 (GCCurrentAffairs) The leadership of the Boeing plane manufacturer refused to fix the problems of Boeing 737 MAX jets after the Lion Air crash in Indonesia, local media reported on Wednesday.

Two Boeing 737 MAX planes have crashed over the past several months: one in Indonesia in October 2018 and another in Ethiopia in March. In the wake of the latest crash, aviation authorities and carriers around the world have either grounded all 737 MAX series aircraft, or closed their airspace to them.

According to The New York Times newspaper, pilots from the American Airlines called on Boeing to fix problems of Boeing 737 MAX jets weeks after the crash in Indonesia. During a closed-door meeting pilots even asked Boeing to push the authorities to ground all 737 Max aircraft.

The plane manufacturer, however, refused to fix the issues saying that it expected pilots to be able to cope with the problems.

“No one has yet to conclude that the sole cause of this [Lion Air crash] was this function on the airplane,” Boeing’s Vice President Mike Sinnett said on November 27, referring to the Maneuvering Characteristics Augmentation System (MCAS), which is now thought to be behind both fatal accidents involving Boeing 737 MAX jets.

MCAS commands automatically push down the jet’s nose in case of a critical angle of attack. However, when the information coming from sensors is wrong, such actions of the security system may pose a danger to the plane as MCAS commands may overpower pilots’ attempts to pull up the nose of the jet.

Moreover, according to The Wall Street Journal, the Boeing company informed neither the US Federal Aviation Administration nor airlines about the fact that the system, which warns pilots about malfunctioning sensors and which was available on earlier Boeing planes, had been deactivated on Boeing 737 MAX jets. In order to make the standard warning system available, airlines had to buy a package of additional security measures.

According to investigators, pilots of the crashed Ethiopian Airlines jet needed more than four minutes to realize that incorrect data from sensors urged MCAS to push the nose down in a situation when there was no need in that.
