MY TAKE: What the Ethiopian 737 Max 8 crash should tell us about the safety of ‘smart’ jetliners

When news broke about the crash of a Ethiopian Airlines Boeing 737, the first question that popped into my head was whether an older 737 model, still using the flawed rudder actuator, might have been involved.

Of course it was actually the newest iteration of the 737, the Max 8. I’m no longer covering aviation. But having chronicled the saga of the 737 flawed rudder design, which Boeing ultimately replaced, here is what I’m wondering:

•I wonder if this will turn out to be yet another in a long line of the manufacturer and/or the airline pushing the edge of the safety envelope, for commercial reasons, with a catastrophic result that should have been anticipated and accounted for.

•I wonder if there is a trail of maintenance records of related, precursor glitches occurring in the Max 8 fleet.

•I wonder how rigorous the FAA was in vetting and approving the safety margins for the advanced functionalities in the Max 8’s complex, automated controls intended to extend the range and capacity of not just the Max 8, but also other 737 models now routinely being used on long-range flights, including from the U.S. mainland to my home state of Hawaii.

If there is any evidence of the steady thinning of the 737’s safety margin translating into operational hiccups that point to the Ethiopian Airlines catastrophe, it should exist in the FAA Service Difficulty Reports airlines are required to file.

This is likely where plaintiff attorneys representing victims will hunt — for leverage to win claims for their clients.  However, with so much at stake, it wouldn’t surprise me if there’s a big push by the defendant attorneys representing Boeing and the airline to settle all victims claims quickly for higher than normal amounts, thus shutting down the plaintiff attorneys.  This is what happened in the Lauda Air 767 crash in Thailand, caused by a malfunctioning thrust reverser.

It’s worth noting that Boeing launched the 737 in the 1960s as a small, short-haul transport under intense competitive pressure from McDonnell Douglas’ hot selling DC-8. And it was competitive pressure that drove Boeing to persuade the FAA to relax ETOPs rules limiting the use of twin jets for very long overseas flights, first to enable trans-oceanic 777 and 787 flights, and then trans-oceanic 737 flights.

The frequency of major air disasters has been at a publicly acceptable level for a long time. But this disaster shows the safety margin of “smart” jet transports needs more attention. The grounding of Max 8s reinforces that notion. I hope regulators and the industry honor the 157 lives lost this week, and address the systemic factors, and well as the specific cause, that precipitated this tragedy.
