Boeing, the door of the 737 Max 9 comes off in flight. The US begins “immediate” inspections of 171 planes – Corriere.it

The American civil aviation authorities have ordered immediate inspections of 171 Boeing 737 Max 9s — nearly 80% of those in service worldwide — after a piece of fuselage from an Alaska Airlines jet blew off during a flight Friday afternoon, forcing an emergency landing. The decision comes some time after the carrier itself had decided to temporarily ground all its 65 Boeing 737 Max 9 aircraft. According to the FAA, each inspection will take between 4 and 8 hours. While experts wonder how it was possible for a newly assembled jet to present such problems. (Here is more information on which airlines use these planes).

The link

Alaska Airlines Flight 1282 departed at 4.52pm local time on Friday (1.52am Saturday night in Italy) from Portland, Oregon, with 174 passengers and 6 crew members and destination Ontario, California. But just arrived at 16,300 feet (4,968 meters) — six minutes after takeoff — began to descend returning towards the original airport, flying for just 19 minutes in total, as shown by the traces of the specialized site Flightradar24. The fact that the accident occurred immediately after take-off averted worse consequences: the passengers at that moment were still wearing their seat belts and there was no one in seat 26A – the one closest to the door.

The dynamics

Once on the ground, a person was treated for minor injuries. Passengers told via social media and local TV that the door suddenly came off in flight: in that moment the Boeing was flying at 711 kilometers per hour. In seats 26B and 26C there was a mother with her son: the boy had his shirt torn off as he was sucked into the hole in the fuselage. Technically that tailgate becomes an emergency exit in particular configurations (e.g. a greater number of seats), but not in this case. If you can observe the shape from the outside, you won’t notice it from the inside because what you see is the internal lining and the window. This is why when the tailgate blew up many were taken by surprise.

At that point the oxygen masks came downdue to the depressurization of the cabin, and everyone wore them while waiting for the descent to Portland.

We have an emergency, Alaska 1282 herea female voice — one of the pilots — says at the control tower, according to recordings provided by LiveAtc. We have declared an emergency. We are depressurized. We have 177 passengers on board.

Grounding

Alaska Airlines Flight 1282 crashed this evening shortly after departure, the carrier confirmed in a statement emailed to reporters. The plane landed safely. It was later Ben Minicucci, CEO of the company, who declared that following the event we decided to take the precautionary measure of temporarily ground our fleet of 65 Boeing 737 Max 9s. Each aircraft – continued the CEO – will return to service after complete maintenance and safety inspections which we expect to complete within a few days.

Delivered 2 months ago

Alaska Airlines did not provide information on possible causes. The National Transportation Safety Board and the FAA wrote via social media that they are investigating and will publish updates as soon as they become available. The manufacturer, Boeing, will also do the same. “Safety is our top priority and we deeply regret the impact this event has had on our customers and their passengers,” the manufacturer explains in a statement. We fully agree and support the FAA’s decision to require immediate inspections of 737 Max 9 aircraft with the same configuration as the affected aircraft.

The aircraft involved was delivered on 31 October 2023 — according to what the Courier can see inside the specialized ch-aviation database — and the first flight with passengers took place on November 11th: since then it has completed 145 trips, according to Flightradar24.

The two alarms of January 4th

The specialized site The Air Current reveals, citing two sources familiar with the matter, that the plane — registration N704AL — had shown indications of pressurization problems on January 4. The first alert appeared during the taxiing phase immediately after landing. The second later, the same day, but this time in flight.

The specimen

The Max is the most recent — and least polluting — version of the classic 737, one of the most widely used single-aisle airplanes in the world. Since it entered service — in 2017 — it has accumulated over 6.5 million hours in flight, according to the latest data provided by Boeing.

Ma in 2018 and 2019 — with incidents in Indonesia ed Ethiopia (346 deaths) of the slightly smaller version, the Max 8, all models were grounded, including the Max 9, for almost two years all over the world. The model returned to service only after Boeing made changes to the automatic flight control system caused the crashes.

The numbers provided by ch-aviation show that There are 209 Boeing 737 Max 9 aircraft active in the world who fly with Aeromxico, Alaska Airlines, Copa Airlines, Air Tanzania, Corendon, Flydubai, Icelandair, Lion Air, Scat Airlines, Turkish Airlines, United Airlines. That of Alaska Airlines involved in the accident it has 178 seats it’s a Current market value of just over $58 million.
