The 787's latest problem mirrors production issues discovered over 2020 and 2021 that included improperly fitted shimming that led to paper-thin gaps between surfaces on the Dreamliner's fuselage.

The problem involves a fitting for the 787's horizontal stabilizer installed by a Boeing production facility in Salt Lake City, Utah, the company said. The horizontal stabilizer, located at the base of an aircraft's tail, allows a plane to maintain longitudinal balance while flying.
Excellent design choices all around. Better sleep on long flights. Because the 787 is pressurized at about 6,000 feet rather than 8,000 feet, you'll breathe easier. More oxygen in your lungs means better sleep, less chance of headache, no difficulty breathing (flying at altitude is like sleeping at a ski resort).
The FAA said the leaks could damage critical equipment and lead to a “loss of continued safe flight and landing.” The agency said one airline found wet carpet in the cockpit of a plane and, when it inspected its entire fleet of 787s, found “multiple” planes with leaking faucets.
Incredibly safe. The 787–8, —9 & —10 are as safe as it's going to get in aviation. The issue with the 787 spacing issues — where gaps are larger than 0.005 inches — is a fatigue and cycles related issue. In normal manufacturing, their are manufacturing tolerances to account for slight differences in part builds.
On January 17th, 2013, the FAA ordered the entire 787 fleet across all airlines to be grounded, and the NTSB launched an investigation. The culprit was eventually identified as a lithium-ion battery. A cell within the battery was believed to have short-circuited, causing what is known as a thermal runaway.
The Boeing 787 has similar safety features to the 777, but also features improvements such as a wider and longer aisle space for passengers and smoother engine takeoff capability which can reduce air turbulence and improve safety during takeoffs.
The typical lifespan of airlinersThe composite-driven Boeing 787 Dreamliner is designed for 44,000 flight cycles. These jets can theoretically last several decades with an average of two flight cycles a day. Unlike commercial airliners, fighter jets are unique due to their mission requirements.
To combat the sound of jet-blast from the rear of the engine, Boeing, General Electric, and NASA developed serrated edges called chevrons for the back of the nacelle and the engine exhaust nozzle. The chevrons reduce jet blast noise by controlling the way the air mixes after passing through and around the engine.
This high aspect ratio wing design combined with efficiency enhancing raked wing tips allow the 787 to be one of the fastest commercial aircraft (Mach 0.85 cruise speed) while consuming less fuel than today's comparably sized aircraft.
How long can a 787 fly without engines? Can a plane fly if all its engines have failed? A passenger aircraft will glide perfectly well even if all its engines have failed, it won't simply fall out the sky. Infact it can fly for around 60 miles if it loses its engines at a typical cruise altitude of 36,000ft.
The Bottom Line: The Airbus A350-900 and Boeing 787-9 are very similar aircraft, suited for similar missions. As one would expect, the slightly larger A350-900 has a seat-mile cost advantage, while the 787-9 has an advantage in cost per block hour. These aircraft are competitive, and nearly tie in economic performance.
On board the Boeing 787-9, you can expect a new, comfortable travel experience and many innovations that will make your flight even more relaxing in the future. Look forward to the Dreamliner effect on your next trip.

Exacerbating the problem for some passengers, the bulge of the wall between windows doesn't always align well with the seat rows and, every few rows, the projection of the wall robs the window seat passengers of a couple of inches of already tight shoulder space.
