Commentary: Boeing’s Tylenol moment and the need for radical transparency
By Judson Rollins
March 13, 2019, © Leeham News: The traveling public’s faith in Boeing – and that of regulators in dozens of countries – has clearly taken a beating.
The 737 MAX has now been grounded or banned in nearly every jurisdiction in which it was operating just a few days ago.
Sunday’s tragic accident in Ethiopia bears an uncanny resemblance to the circumstances of the October crash of Lion Air 610, a fact which Boeing has tried 
to downplay by arguing that both accidents are still under investigation. The earlier accident is widely believed to have been caused by repeated nose-down trim responses driven by the MAX’s Maneuvering Characteristics Augmentation System (MCAS), which in turn may have been influenced by inputs from a faulty angle-of-attack (AOA) sensor.

EASA grounds, bans 737 MAX; FAA remains silent
March 12, 2019, (c) Leeham News: EASA, the European air safety regulator, grounded the Boeing 737-8/9 operated by EU airlines and banned operation of the airplanes operated by third-party airlines/countries.
The press release is here.
The US Federal Aviation Administration still is silent about grounding the airplanes in the US.
UK bans MAX; China checked with Boeing, FAA before grounding
March 12, 2019, © Leeham News: Australia and the United Kingdom today joined a growing list of countries banning the Boeing 737 MAX from operating in or through their 
airspace.
The UK’s decision to ban the MAX is, up to now, the most important development in the growing crisis of confidence in the safety of the MAX.
The UK and continental Europe’s regulators, EASA, are considered tough regulators who usually work in concert with the USA’s Federal Aviation Administration. That the UK authority is now ahead of the FAA is crucial. If EASA follows suit, the blow to the FAA and to Boeing will be huge.

About 40% of MAX fleet now grounded-but not by FAA
March 12, 2019, © Leeham News: About 40% of the world’s in-service Boeing 737 MAX fleet were grounded by the end of yesterday, Seattle time, after more governments and airlines banned operations.
Singapore was the latest to ban MAX operations from its air space.
The US Federal Aviation Administration said yesterday there isn’t enough information yet from the Ethiopian Airlines crash Sunday to conclude a grounding order is necessary.
But it added that it will issue an order for a mandatory action by April to make improvements to the flight control system. Boeing late Monday confirmed a software upgrade is in the works for its MCAS stall recovery system used on the MAX.
LNA reported early Monday that a plan to implement a software upgrade following the October crash of a Lion Air MAX 8 had not been implemented.

March 11, 2019, © Leeham News: Indonesia regulators today joined China, Grand Cayman Airways and Ethiopian Airlines in grounding the Boeing 737 MAX pending investigations or inspections.

The crash killed all 157 people on board five months after a Lion Air 737-8 crash that killed 189 passengers and crew. Lion Air is an Indonesian carrier. The airline’s JT610 crashed 12 minutes after take off.
