Boeing didn't disclose possible fault in flight feature suspected in Lion Air crash: WSJ The automated stall-prevention system found on Boeing 737 MAX 8 and MAX 9 models can push a plane's nose down "unexpectedly and so strongly" that pilots can't pull it back up even when flying manually, The Wall Street Journal reported.

Boeing Close to Issuing Safety Warning on 737 Max© Bloomberg Opening Day Highlights At The 2018 Farnborough Airshow (Bloomberg) -- Boeing Co. is preparing to send a bulletin to operators of its new 737 Max models warning that erroneous readings from a flight-monitoring system can cause the planes to aggressively dive, said a person familiar with the matter.

The warning is based on preliminary findings from last week’s crash of one of the planes off the coast of Indonesia, said the person, who asked not to be named discussing details that are still confidential. The bulletin, which will be released as early as Wednesday morning Jakarta time, will alert pilots to follow an existing procedure to handle the problem, the person said.

Boeing jet crash-lands at Guyana airport, six injured: minister

Boeing jet crash-lands at Guyana airport, six injured: minister A Boeing jetliner carrying 126 people crash-landed at the airport in Guyana's capital Georgetown on Friday, injuring six people, the transport minister said. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.getMedianetNativeAds(true); }); The Fly Jamaica Airways plane was bound for Toronto when it suffered a hydraulic problem shortly after takeoff and returned to the airport, crashing and skidding off the runway, Transportation Minister David Patterson said.

Boeing will certify the Max series under an amended type certificate as part of the 737 family rather than go for a whole new type certificate. This is a controller initiated, non-interactive test sequence that checks the capability of the PRSOV solenoid to close the valve, independent of the torque motor.

737 MAX has it, with the innovative Boeing Sky Interior — a design utilizing modern-sculpted sidewalls, customizable LED lighting, and other On May 4, 2016, the CFM LEAP-1B engine for the 737 MAX was simultaneously awarded Type Certificates by both the European Aviation Safety Agency (EASA)

Under some circumstances, the Max jets will automatically try to push down the nose if they detect that an aerodynamic stall is possible. One of the critical ways a plane determines if a stall is imminent is a measurement known as angle of attack, which senses the angle at which the wind is passing over the wings.

A Lion Air 737 Max 8 carrying 189 people dove into the Java Sea at high speed on Oct. 29 minutes after takeoff. The pilots, who were dealing with an erroneous airspeed indication, had radioed a request to return to Jakarta to land, but never turned back toward the airport, according to Indonesia’s National Transportation Safety Committee and flight-track data.

It wasn’t immediately clear if the airspeed issue had any connection with the angle-of-attack matter. A spokesman for Chicago-based Boeing couldn’t immediately be reached for comment.
