The aviation business continues to be in shock from a near disaster on January 5, by which a 60-pound “door plug” blew out from a virtually new Boeing 737 Max 9 plane in flight at 16,000 toes, leaving a gaping gap within the fuselage.
In response, the Federal Aviation Administration grounded all 737 Max 9 planes with such plugs, and aviation authorities in different international locations have followed suit.
The business is watching intently.
Plenty of information protection has emphasised the impressive safety record of the worldwide airline business, notably since an Alaska Airways crew managed to land the aircraft with no fatalities. I commend the excellent efficiency of airline workers, air site visitors controllers, and emergency responders who achieved this spectacular feat.

Security isn’t free
Airways have plenty of bills. Some, akin to jet fuel, are simpler to calculate. Others, akin to emergency exits, are extra opaque to vacationers.
Imagine it or not, each functioning emergency exit comes at a value for an airline. Every requires routine upkeep and frequent inspections—for instance, to make it possible for emergency evacuation slides work correctly—and flight attendants should employees emergency exits throughout takeoff and touchdown for security causes.
In different phrases, each working exit comes with related prices in salaries, well being advantages, pension plans, coaching, and associated bills. Sealing off an emergency exit cuts prices.
However is each a type of emergency exits essential? From the U.S. authorities’s perspective, not essentially.
Why you get extra emergency exits in Indonesia
Within the U.S., airways should adjust to federal aviation rules, which dictate plane upkeep procedures and in-flight personnel assignments—and minimal requirements for emergency exits.
The difficulty is that Boeing sells the identical airplane to totally different airways with totally different wants.
Boeing notes that its 737 Max 9 can carry as much as 220 passengers, which, beneath U.S. rules, requires it’s constructed with a particular variety of emergency exits. This dense seating configuration is frequent amongst lower-cost world airways akin to Jakarta-based Lion Air.
Nonetheless, given People’ need for legroom, most U.S. carriers are geared up with significantly fewer than 220 seats—and when there are fewer than 190 seats, the foundations permit fewer emergency exits to be in service. The Alaska Airways Max 9 had simply 178 seats.
Below these situations, the federal guidelines permit air carriers to disable these exits and plug the openings. That’s exactly what occurred with Alaska Airways Flight 1282—and the way “door plug” all of the sudden entered the American vernacular.
Though this type of workaround is permitted, it’s unclear to me that that is in one of the best curiosity of air security. Wouldn’t it’s higher for the FAA to require that every one exits can be found to be used in an emergency, no matter plane seating capability, even when it required some further expense for airways?
A worrying security file
The 737 Max is a aircraft of many firsts—not all of them optimistic.
The Max is the most recent addition to Boeing’s 737 household of plane. The 737 household has far eclipsed all rivals because the most popular commercial airliner ever built, with greater than 10,000 bought worldwide since its introduction in 1967.
Some carriers, akin to Southwest Airways within the U.S. and Ryanair in Eire, fly solely 737s; it’s a important factor of their low-cost enterprise technique. By flying only one kind of plane, these airways considerably enhance scheduling flexibility whereas chopping upkeep and coaching prices.
That’s all to say that demand for the most recent 737 was excessive. In 2017, when the FAA licensed the 737 Max protected for flight, Boeing had already received greater than 3,600 new orders from 83 clients.
However very shortly afterward, two crashes that together killed 346 people grounded the 737 Max for practically two years—one other first as the longest airline grounding in aviation history. Destined to revenue $12 million on the sale of every $121 million Max, there was significant incentive for Boeing to press on with Max improvement despite the fact that it had already proved to be a dangerously problematic plane design.
In 2020, the FAA recertified the Max as “safe for flight”; by 2023, Boeing had logged greater than 7,000 complete orders for the Max, far eclipsing the sale of every other kind of airliner. This truth alone ought to boost security considerations. It could quickly show unattainable to keep away from flying on a 737 Max, notably within the U.S. home market. United, American, Southwest, and Alaska airways all currently fly the Max.
