While the 787 Dreamliners have not been grounded, the FAA had ordered a halt to deliveries of the widebody jet between May of 2021 and July of 2022 as it looked into questions about quality control during its assembly process.

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 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.
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.

The Dreamliner is a successful aircraft, still in production with more than 1600 delivered or on order. The list price for a new Boeing 787-8 is $239 million dollars. Yet even as international travel opens again for these long-range aircraft, two Dreamliners barely ten years old are waiting for the wrecker's ball.

Additionally, for the Boeing 747-400 and Boeing 787-8, there is an automatic aileron lockout system in place. This prevents the aircraft from performing any manoeuvres that might stress the airframe, such as a roll upside down.
The longer the 787s remained on the ground, the more it would cost to get them to fly again, due to the maintenance work required. As a result, they were no longer airworthy.
The 787 was designed to be the first production airliner with the fuselage comprising one-piece composite barrel sections instead of the multiple aluminum sheets and some 50,000 fasteners used on existing aircraft. Boeing selected two new engines to power the 787, the Rolls-Royce Trent 1000 and General Electric GEnx.
•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 seats are so cramped in economy that the legroom of a similar seat on a 777 or a 747 feels like a business-class seat. Intelligent engineering allows for seat-backs to recline but to compensate, the seat bottom lunges forward — thereby only providing an illusion of a recline.
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.
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.
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.
It's the latest in a long and very expensive litany of 787 quality woes. The affected attachment fitting is provided by a supplier and installed on the horizontal tail at Boeing's manufacturing facility in Salt Lake City. The defect is a small, paper-thin gap in the attachment, Boeing said.
The Dreamliner's lightweight composite structure contributes to reduced noise levels, both inside and outside the aircraft. The use of advanced soundproofing materials and quieter engines keeps the cabin environment more tranquil for passengers.
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.
To start the Boeing 777 vs 787 comparison, we must say that the 787 is a more fuel efficient aircraft than the 777 thanks to its use of composite wings and more aerodynamically efficient design.
