Following two similar plane crashes in Indonesia (Oct ’18) and Ethiopia (March ’19) President Trump has issued an emergency order grounding a specific Boeing 737 airliner. The “Max 8” and “Max 9” models are being grounded out of an abundance of caution while U.S. and international authorities await the findings from crash investigation.
WASHINGTON (AP) — The U.S. is issuing an emergency order Wednesday grounding all Boeing 737 Max 8 and Max 9 aircraft “effective immediately,” in the wake of the crash of an Ethiopian Airliner that killed 157 people, President Donald Trump said.
“All of those planes are grounded, effective immediately,” Trump said during a scheduled briefing on border security.
Trump said any airplane currently in the air will go to its destination and then be grounded. He added all airlines and affected pilots had been notified.
Trump said the safety of the American people is of “paramount concern,” and added that the FAA would soon put out a statement on the action.
Trump said the decision to ground the aircraft “didn’t have to be made, but we thought it was the right decision.”
The president insisted the announcement was coordinated with aviation officials in Canada, U.S. carriers and aircraft manufacturer Boeing.
“Boeing is an incredible company,” Trump said. “They are working very, very hard right now and hopefully they’ll quickly come up with an answer.” (AP Report Link)
Prior to this decision, it appeared that Boeing was concerned about a specific element to flight software – SEE HERE:
BOEING – March 11, 2018 […] 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.
[…] A pitch augmentation control law (MCAS) was implemented on the 737 MAX to improve aircraft handling characteristics and decrease pitch-up tendency at elevated angles of attack. It was put through flight testing as part of the certification process prior to the airplane entering service. MCAS does not control the airplane in normal flight; it improves the behavior of the airplane in a non-normal part of the operating envelope. (read more)
