Two crashes led regulators to ground a bestselling jet

The signal

In March 2019, regulators grounded Boeing's 737 MAX after two fatal crashes within five months, an aerospace-sector event about certification and manufacturer disclosure rather than about a single accident. Boeing's own annual report states plainly that 'on March 13, 2019, the Federal Aviation Administration (FAA) issued an order to suspend operations of all 737 MAX aircraft in the U.S.' European regulation moved a day earlier: the EU Aviation Safety Agency's own press release records that it suspended 'all Boeing Model 737-8 MAX and 737-9 MAX aeroplanes in Europe' from 19:00 UTC on 12 March 2019, following the Ethiopian Airlines flight ET302 crash, and separately barred third-country operators of the type from EU airspace.

The evidence

The two documents measure different things. EASA's release is a regulator's own contemporaneous order, dated and scoped to European airspace, issued while the accident investigation, led by Ethiopian authorities with U.S. National Transportation Safety Board support, was still open; it states it was 'too early to draw any conclusions as to the cause of the accident'. Boeing's 10-K, filed with the SEC on 31 January 2020 for fiscal year 2019, is the manufacturer's own dated account of the consequence: production cut 'from 52 aircraft per month to 42 per month' in the second quarter of 2019, then a temporary halt announced for January 2020, and 'an earnings charge of $8,259 million, net of insurance recoveries of $500 million, in 2019'. A related 8-K filing from 21 January 2020 shows Boeing still estimating, a year after the crash, that 'the ungrounding of the 737 MAX will begin during mid-2020', a forecast the filing attributes to the company, not to regulators.

Timeframe and confidence

Confidence in the grounding date, the European order's scope, and the disclosed production and financial figures is high, because each is a dated statement from the regulator or the manufacturer. Confidence in a single worldwide grounding date is lower from these sources alone: EASA's action covered Europe, Boeing's filing dates only the U.S. order, and other regulators acted on schedules not documented here. Treating 'grounded worldwide' as a single date is an editorial simplification these records do not support.

What would change the reading

A dated order from a third regulator, or a consolidated ICAO timeline, would show how synchronised the worldwide grounding actually was. A later Boeing filing recording when deliveries resumed, against the 'mid-2020' estimate, would show how accurate that forecast turned out to be.

• How many days elapsed between the first national regulator's grounding order and the last, and what does that spread say about regulatory independence versus coordination?
• Did the actual return-to-service date match Boeing's mid-2020 estimate, and if not, by how much did it slip?
• What changed in the certification process itself, as opposed to the aircraft's software, between the grounding and the eventual ungrounding?

A grounding order and a financial charge are each precise, dated facts. The narrative connecting them, a single global grounding, compresses many national decisions, and the filings opened here document only the U.S. and European strands of that chronology.
