Boeing has issued a preliminary ‘Operations Manual Bulletin (OMB)’ for the 737 MAX, following the crash of Lion Air flight JT610 last week.
This OMB is a safety notice for all operators of the aircraft type, warning that issues with the AOA (Angle of Attack) indicator could cause the airplane to abruptly descent.
On October 29th, a Lion Air Boeing 737 MAX 8 on flight JT610 crashed into the sea shortly after takeoff from Jakarta Airport. An official investigation is still going on, however a lot of signs already indicate that faulty flight speed, altitude and AOA displays could have caused the accident in which all 189 people on board died.
The 737 MAX is the latest generation of Boeing’s 737. It has almost 5000 orders, of which 219 have been delivered so far. The aircraft entered commercial service in May 2017 with Malindo Air, a Malaysian subsidiary of Lion Air Group.
