Tech Security Update

The 737 Max is the latest generation of Boeing's workhorse 737 series.

The main difference between it and the previous model is that the plane has bigger, more fuel-efficient engines.

Boeing had to mount the larger engine farther forward and higher on the wing than on the previous generation, changing the aerodynamic qualities of the entire plane.

Boeing designed a software program to to compensate for the fact that the engine size and placement could make the plane's nose drift up compared to the older generation. The flight control software, which was meant to only activate in certain circumstances, was called MCAS — the Maneuvering Characteristics Augmentation System.

MCAS would take control of the trim stabilization on the plane's tail, changing its angle to compensate for the jet's nose drifting upward.

In both crashes, MCAS appeared to have activated erroneously after one of each plane's angle of attack sensors became damaged.

Part of what may have contributed to the crashes was that Boeing failed to highlight MCAS in the pilot manual for the plane, simply describing certain actions that could be taken to disable it if the plane experienced unusual behavior.

As part of the return to service, Boeing redesigned MCAS to rely on a second angle of attack sensor, so that if one becomes damaged and gives a faulty reading, the program will not activate. The FAA, other regulatory bodies, and Boeing also devised a series of pilot training requirements which pertain to MCAS, its effects, and situations that could cause it to kick in.

I'm personally confident that they've gotten it right this time, partly because of the unprecedented scrutiny on the recertification process. With input from other global regulators and independent assessments, and the pressure to avoid even the appearance of impropriety, I do not think the plane could possibly be returned to service without the faults fully addressed.

Despite the approval from the FAA and from other national aviation regulators, including in Europe and Brazil, family members of crash victims remain deeply suspicious of the plane, and characterized American's media event as a PR stunt.

"The promotional flight was arranged by the American Airlines marketing team simply because the company made the mistake of buying more Max aircraft than almost any other airline," Michael Stumo, whose 24-year-old daughter Samya was killed in the crash of Ethiopian Airlines flight 302, said in a statement. "Passengers should avoid this aircraft because others are safer."

Notably, airlines have stressed that they will only bring the Max back to service when their pilots are confident in it. At American's presentation, several pilots who represented their union during Max return planning said that they were satisfied with the updates and new requirements.

And that's why I was willing to step aboard a Max today.

The COVID-19 pandemic has forced airlines to ground huge portions of their fleets as travel demand fell to record-breaking lows nearly overnight.

Although some demand has returned — particularly around Thanksgiving — travel remains down more than 65% compared to 2019 levels, and new, dramatic spikes in coronavirus cases nationwide make it likely that the modest recovery will stall, as it did around spikes in early summer.

Even so, American has decided to pull thier Max fleet from storage and get the planes back into service as quickly as possible.

Chief Operating Officer David Seymour said that the airline was eager to bring the plane back thanks to its improved fuel efficiency over other models, despite prices for jet fuel being near historic lows.

Erik Olund, managing director at the airline's Tulsa, Oklahoma 737 maintenance base — where most of its Max planes have been kept in storage — hinted at another possible reason. The airline's maintenance workers have spent more than 64,000 man-hours maintaining the planes while they are in storage, a costly enterprise.

American Airlines plans to be the first US carrier to reintroduce the Max, and is in the process of installing Boeing's fixes and preparing the planes to fly again after nearly two years on the ground.

American's passenger service on the Max is expected to begin on December 29 with a flight between New York's LaGuardia and Miami. United plans to return it to service sometime in the first quarter of 2021. Southwest, the biggest Max customer, will wait until the second quarter.

American may not be the first airline in the world to reintroduce the plane, though; Brazillian carrier GOL is attempting to reintroduce the plane by December 10, according to Bloomberg.

Aside from the knowledge that we were the first passengers on the jet since the grounding, the flight was totally unremarkable.

The interior of the plane was identical to the previous generation 737-800 I had flown the night before.

The safety demonstration was the same, as was the location of the emergency exits — in fact, the Max uses the same seat-back safety card as the previous generation.

There were only two real differences between this and a normal commercial flight on an older generation 737.

First, the bigger, more efficient engines were noticeably quieter.

Second, a lot of the passengers were taking photos or filming TV segments — definitely a departure from the norm.

After about an hour in the air, we began our descent into Tulsa. The flight attendants took their seats and chatted with each other, just like normal, and we all put away our laptops and cameras.

The flight landed with a sense of anticlimax, and our return flight was just as unremarkable.

I would not hesitate to fly the Max again, but I doubt you'll find me on one anytime soon. Despite a variety of safety measures that US airlines are taking during the pandemic, being on commercial flights, spending the night in a hotel, and being around other people felt unnecessarily risky as the pandemic continues to rage uncontrolled.

While American's flight attendants did a good job of enforcing mask during my flights to and from DFW — and some evidence suggests flying itself is relatively safe — I found the number of maskless people at the hotel and in the airport to be jarring. Especially on the day that US set a new record for COVID-19 hospitalizations, surpassing 100,000 for the first time.

Ultimately, the pandemic served to underscore my comfort flying on the 737 Max. Although I was on a plane that had been involved in two deadly crashes as a result of design and certification flaws, that was the least risky aspect of the trip. Now, I'm headed for at least a week of quarantine and a COVID test, and hoping that I stay healthy.
