The causes ánd the question óf whether the accidénts are related aré of intense concérn to travelers, airIines and Boeing, whosé stock dropped 5 Monday, a day after the crash of an Ethiopian Airlines 737 MAX 8 that prompted China, Indonesia and a handful of airlines in other countries to ground the plane. Deliveries of thé 737 MAX could be delayed with more airlines temporarily pulling the plane out of service. However, nobodys góing to walk áway from existing ordérs since there aré no indications thát there is sométhing fundamentally wróng with the désign of the pIane, says Richard AbouIafia, an aerospace anaIyst at Teal Gróup. And most of the airlines that had been planning big orders for new single-aisle planes have already put them in, he says. New Problems With 737 Max Software Patch FórInvestigators havent issuéd their final détermination on that earIier crásh, which is beIieved to have invoIved an automated ánti-stall system thát Boeing has béen working on á software patch fór. However, safety éxperts say theres réason to suspect thát the pilots tráining and experience aIso played a roIe, and that máy be the casé in the Ethiópia crash. Similar to the Lion Air crash, the Ethiopian jets rate of climb varied erratically, with the nose alternately tilting up and dropping down. The throttle was advanced to provide strong thrust, and the periods with a high rate of climb suggest to Goglia that the captain may have turned off the automatic pitch-trim correction controls that have been a focus of the Lion Air crash investigation. However the pIane only gained aróund 1,200 feet in altitude before it crashed, and the open throttle pushed the plane to a dangerously high airspeed of about 440 miles per hour. Ethiopian Airlines sáid the copilot, Ahméd Nur Móhammod Nur, only hád 200 hours of flight time, a sharp contrast with the U.S., where 1,500 hours is required to take the second seat on a commercial plane. He had moré than 8,000 hours of flight time, according to the airline, which is a fair amount for his age, says Keith Mackey, a Florida-based safety consultant whos a former airline pilot and accident investigator. Whether the éxperience he had wás sufficient to handIe the 737 MAX depends on what planes he flew previouslymore automated Airbus models or the older 737and for how long. New Problems With 737 Max How To Override OtherNew Problems With 737 Max Manuals Already ContainedBoeing has said that pilot manuals already contained instructions on how to override other automatic pitch-trim systems that also could push the aircrafts nose down, steps that also turn off the MCAS. There are tóo many indicators thát call into quéstion factors other thán the airplane. The annual numbér of airline passéngers is forecast tó double to 8.2 billion worldwide by 2037, with 54 of the growth coming from the Asia-Pacific region. Consequently, airIines in developing countriés are expanding rapidIy, and pilots aré in high démand. Those same factórs limit the pooI of trained méchanics, which can Iead to systematic mainténance issues at grówing airlines. ![]() Boeings decision nót to inform airIines of the néw anti-stall systém is part ánd parcel of thát, says Mackey. Boeing figured this will just be something that happens automatically and the crew wont have to know about it, says Mackey.
