Boeing 737 MAX 8 ET 302 registration ET-AVJ from Addis Ababa (Ethiopia) to Nairobi (Kenya) with 149 passengers and 8 crew, was lost 10 March 2019 shortly after takeoff at 08:44L (05:44Z). There were no survivors.

Boeing 737 MAX 8 registration ET-AVJ performing flight ET-302 from Addis Ababa (Ethiopia) to Nairobi (Kenya) with 149 passengers and 8 crew, departed Addis Ababa's runway 07R and was climbing out of Addis Ababa when the aircraft levelled off at about 9000 feet MSL, radar contact was lost shortly after at 08:44L (05:44Z). The aircraft wreckage was found near Ejere at approximate position N8.8772 E39.2512. No survivors were found.

In a subsequent press conference on Mar 10th 2019 Ethiopian Airlines reported the crew reported difficulties and requested a return to Addis Ababa. The captain was with Ethiopian Airlines for 9 years and had about 8000 hours of flight experience, a first officer with 200 flight hours assisted, there were 35 nationalities amongst the 149 passengers. The crash site appears to be consistent with a steep dive, the aircraft is right inside the ground. The aircraft had undergone last "rigorous first check maintenance" on Feb 4th 2019. The aircraft had last operated to and from Johannesburg (South Africa) arriving back in Addis Ababa in the morning of Mar 10th 2019 before departing for the accident flight.

Link to Aviation Herald discussion.
The incident appeared similar to the 29 October 2018 crash of Lion Air 610, operated by a B38M.

Indonesian carrier Lion Air Flight 610 on October 29 crashed into the sea soon after takeoff with the loss of all aboard, apparently due to the erroneous data from a faulty Angle of Attack sensor, which caused the MCAS (Maneuvering Characteristics Augmentation System) to assume the plane was about to stall, which activated the downward force on the Stabilizer Trim to get the nose down. Link to BBC article.

This aircraft had been written up as having a faulty AOA indicator for previous flights it had taken. It is unclear if Lion Air had performed adequate maintenance procedures after the reports or withdraw the aircraft from service until the fault could be completely cleared.

Link to Aviation Herald discussion.

“Instead of switching off the Stabilizer Trim the pilots appear to have battled the system.” Link
Boeing 737 MAX and MCAS: See “What is the Boeing 737 MAX Maneuvering Characteristics Augmentation System?”, updated November 17 to explain the MCAS and electric trim override operation, here: link.

Boeing has stated a revised MCAS is in the works, and the FAA is expected to issue an AD note when the MCAS update is done. This is expected to occur in early April, 2019.

355 B38M deliveries have been carried out through 1 March 2019, out of 5,123 orders. Link to Wikipedia B38M list of Airlines, orders and deliveries.
Ethiopian Airlines ordered 25 Boeing 737 MAX 8 (B38M) and at the time of the crash of ET 302 on 10 March 2019. ET also operates 10 Boeing 737-700 and 16 Boeing 737-800 aircraft as part of its fleet.

Ethiopian Airlines is the flag carrier of Ethiopia, and commenced operations on 8 April 1946, expanding to international flights in 1951. The firm became a share company in 1965 and changed its name from Ethiopian Air Lines to Ethiopian Airlines. The airline has been a member of the International Air Transport Association since 1959 and of the African Airlines Association (AFRAA) since 1968. Ethiopian is a Star Alliance member, having joined in December 2011.

As of November 2017, the carrier served 105 international and 20 domestic passenger destinations and 44 cargo destinations. Ethiopian serves more destinations in Africa than any other airline. Ethiopian Airlines’ fleet consists of 106 aircraft.

So eventually the aircraft will be grounded....either by regulators or just day by day by the airlines.

If TUI, Southwest and Norwegian are the last airlines standing they will be very bold people. Any incidents and they would get sued out if business.

I suppose Norwegian might have issues either way though. Ground the planes and the airline could fail anyway.

From: Federal Aviation Administration Aircraft Certification Service

Date: March 11, 2019

Subject: This message provides information regarding FAA continued operational safety activity related to the Boeing 737-8 and Boeing 737-9 (737 MAX) fleet.

Situation description: Following the accident of an Ethiopian Airlines Boeing Model 737-8 airplane on March 10, 2019, the National Transportation Safety Board (NTSB) as the accredited representative, and the FAA as Technical Advisors, are supporting the Ethiopian Accident Investigation Bureau. The FAA has dispatched personnel to support the investigative authorities in determining the circumstances of this event. All data will be closely examined during this investigation, and the FAA will take appropriate action if the data indicates the need to do so.

External reports are drawing similarities between this accident and the Lion Air Flight 610 accident on October 29, 2018. However, this investigation has just begun and to date we have not been provided data to draw any conclusions or take any actions.

Following the Lion Air Flight 610 accident, the FAA has completed these activities in support of continued operational safety of the fleet:

1) Issued FAA emergency Airworthiness Directive (AD) 2018-23-51 on November 7, 2018

2) Validated that airplane maintenance and functional check instructions on Angle of Attack (AOA) vane replacement were adequate

3) Conducted simulator sessions to verify the Operational Procedures called out in FAA AD 2018-23- 51

4) Validated AOA vane bench check calibration procedures were adequate

5) Reviewed Boeing’s production processes related to the AOA vane and Maneuvering Characteristics Augmentation System (MCAS)

Ongoing oversight activities by the FAA include:

a) Boeing’s completion of the flight control system enhancements, which provide reduced reliance on procedures associated with required pilot memory items. The FAA anticipates mandating these design changes by AD no later than April 2019.

b) Design changes:

i) MCAS Activation Enhancements

ii) MCAS AOA Signal Enhancements

ii) MCAS Maximum Command Limit

Aircraft/engine make, model, and series: The Boeing Company Model 737-8 and 737-9 airplanes (737 MAX)

U.S.-registered fleet: 74 airplanes; Worldwide fleet: 387 airplanes
I'm confused by the last line stating that there ate 74 of them registered in the USA. Recent reports give the count as 34 WN, 24 AA and 14 UA, with UA having the MAX 9 rather than 8. These numbers sum to only 72, so where are the remaining two airplanes? Are the numbers reported for carriers just the number that they own, with the remaining two being owned by leasing companies? AFAIK it's not the case that they're in private (general) aviation or being used for cargo.

I found this article (in French) rather useful for clearly showing which airlines have this aircraft type. From Bluewin news, Swisscom.

The UK Civil Aviation Authority has issued instructions to stop any commercial passenger flights operated on a 737 MAX from any operator arriving, departing or overflying UK airspace.

Edit: OK the CAA tweeted the statement I am quoting then immediately after, deleted the tweet

Second edit: and it is back, I guess a typo in the first tweet:

Ah, sorry, I didn't realize it was more complicated than that. I flew on that route with Ethiopian on Friday. It may not be the same plane. It appears to be a Max I flew on - on the same route. I'll leave it to someoen else to figure out if it's the same exact plane.

Sure hope it wasn't - and feel awful for the staff and all the passengers.

I couldn't catch my flight today - (Not a Max) from Nairobi to Mombassa... Just couldn't face another plane. Took at 6hr train instead and ditched my ticket.

This effectively grounds the TUI and Norwegian 737 Max fleets no?

Norwegian temporarily suspends flights with the Boeing 737 MAX, following recommendations by European aviation authorities

Press Release • Mar 12, 2019 13:50 GMT


Following the decision by the relevant aviation regulatory bodies to temporarily suspend operations of Boeing 737 MAX, Norwegian will not operate any flights with this aircraft type until further notice. We remain in close dialogue with the aviation authorities and Boeing, and follow their instructions and recommendations.

Norwegian has more than 110 Boeing 737–800 aircraft in its fleet, which is not affected by this temporary suspension.

We would like to apologise to customers who will be affected by temporary cancellations and delays, but the safety and security of our customers and colleagues will never be compromised, and once authorities advise to cease operations we will of course comply.

Tomas Hesthammer, Norwegian’s acting Chief Operating Officer said: “In response to the temporary suspension of Being 737 MAX operations by multiple aviation authorities we have taken the decision to not operate flights using this aircraft type until advised otherwise by the relevant aviation authorities. We would like to apologise to customers for any inconvenience caused, however, safety will always remain our top priority.”

I don't think they had much choice, the planes would have been flying half empty anyway.

Don't know about TUI, but I'm guessing that Norwegian has enough 737 NGs to switch to fly to/form GB and assign MAX to other routes.
