Indonesia urges more training for pilots after Lion Air crash

Boeing said it is confident in the safety of the 737 Max family of jets

Boeing said it is confident in the safety of the 737 Max family of jets

A Boeing spokesperson said, "We are taking every measure to fully understand all aspects of this incident, working closely with the investigating team and all regulatory authorities involved".

According to a fresh report in The Wall Street Journal, Boeing appeared to have withheld information about suspected malfunctions with a new flight-control feature, which are believed to have played a role in the deadly Indonesian Lion Air jet crash.

According to the report, Boeing told airlines that such a situation "can result in a steep dive or crash - even if pilots are manually flying the jetliner and don't expect flight-control computers to kick in".

"The bottom line here is the 737 Max is safe", Muilenburg said Tuesday on Fox Business Network. But under unusual conditions, it can push the nose down with such force that crews can't pull it up again.

Jon Weaks, president of the Southwest Airlines Pilots Association, told Bloomberg, "We don't like that we weren't notified".

The pilot of Flight 610 had more than 6,000 flying hours while the co-pilot had more than 5,000 hours, according to the airline.

Indonesia's National Transport Safety Committee is continuing to search for the plane's crash-proof cockpit voice recorder under the sea, it said Monday.

Reuters quoted an unnamed us government official as saying Boeing was expected to unveil a software update to reduce the risks posed by the MCAS. The FAA's emergency directive required that USA carriers revise flight manuals and said the agency "will take further action if findings from the accident investigation warrant". The investigative agency plans to release a preliminary report between November 28 and 29, a month after the crash, as mandated by global treaty. At three different airports, Lion Air maintenance crews tried to fix various problems concerning erroneous airspeed and other data, declaring the plane fit to fly.

"What Boeing conveyed to airlines and pilots was that the B737NG and B737 MAX essentially had similar flight-control features", said a senior commander. Lion Air was one of Boeing's primary foreign customers for the MAX, which is also flown by Southwest Airlines, American Airlines, and Air Canada.

To counteract the anti-stall system, pilots are advised to switch off electric motors in the aircraft's tail that are causing the plane's nose to pitch downward.

Pilots are drilled on how to cut power to the so-called trim system if the plane starts to dive or climb on its own, but that procedure was never linked directly to a malfunctioning angle-of-attack sensor in training or the documentation.

In the past, anti-stall systems have either issued audible warnings to pilots or, as in newer systems, used a sensory feedback system that warns the pilot by putting more resistance on the aircraft's control stick or yoke when the pilot is approaching the critical angle.

The failure of an air safety system is exceedingly rare but not unheard of for new aircraft.
