Boeing must itself ground its 737 Max 8 aircraft till software update is completed (in April)

Boeing put out a statement last night.

For the past several months and in the aftermath of Lion Air Flight 610, Boeing has been developing a flight control software enhancement for the 737 MAX, designed to make an already safe aircraft even safer. This includes updates to the Maneuvering Characteristics Augmentation System (MCAS) flight control law, pilot displays, operation manuals and crew training. The enhanced flight control law incorporates angle of attack (AOA) inputs, limits stabilizer trim commands in response to an erroneous angle of attack reading, and provides a limit to the stabilizer command in order to retain elevator authority. 

Boeing has been working closely with the Federal Aviation Administration (FAA) on development, planning and certification of the software enhancement, and it will be deployed across the 737 MAX fleet in the coming weeks. The update also incorporates feedback received from our customers.  

The FAA says it anticipates mandating this software enhancement with an Airworthiness Directive (AD) no later than April. We have worked with the FAA in development of this software enhancement.

Today a number of other countries and airlines have grounded the aircraft. The UK joined the ban following Ethiopia, Singapore, China, France, Ireland, Germany, Australia, Indonesia and Malaysia. TUI and Norwegian are among the airlines which have also grounded the aircraft.

It seems to me that instead of getting all their lobbyists to cast doubt on pilots or their training it should be Boeing which itself grounds the aircraft. When Boeing itself is introducing the software enhancement as a result of the Lion Air crash, and possibly has the 157 deaths of the Ethiopian crash on their plate, it is unconscionable for them to allow the planes to fly.They cannot lean back and use the FAA as their backstop. The FAA itself needs to develop a backbone when it comes to US manufacturers.

Boeing cannot just take the position that once was accident, the second merely coincidence and wait for a third crash.
