What is the 787 controversy?

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 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 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.

The Boeing 787 is one of the newest planes to come into passenger service. First delivered in 2011, the aircraft has become a favorite for airlines thanks to its extensive range and fuel efficiency. And, for passengers, the travel experience was much better compared to older aircraft.

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.

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.

The typical lifespan of airliners The 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.

What was the 787 meant to replace? At launch, Boeing targeted the 787 with 20% less fuel burn than replaced aircraft like the Boeing 767, carrying 200 to 300 passengers on point-to-point routes up to 8,500 nautical miles [nmi] (15,700 km; 9,800 mi), a shift from hub-and-spoke travel.

The Boeing 787 is known to be a more comfortable and efficient aircraft than the 747, especially for long-haul flights. There are objective differences between both planes. The 787 has newer engines, two fewer of them and more electrical (rather than hydraulic) systems, which means much less cabin noise.

MORE DETAILS

It's just newer. Perhaps the main reason but the 787-10's lack of popularity is due to the simple fact that it is a newer aircraft. While the 787-8 took its first flight in 2009 and the -9 in 2013, the -10 didn't take off until 2017. In fact, the -10 was only officially launched in 2013, at the Paris Air Show.

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.

MORE DETAILS

Boeing continued to build the 787 even while it was prevented from making deliveries in late 2021 and much of 2022. It was able to deliver much of that backlog once it was given clearance to resume deliveries, as it delivered 34 Dreamliners between August of last year and January of this year.

Did you know that the 787 can deploy a propellor underneath its fuselage? It's called a RAT.

Designed for optimized fuel efficiency Boeing states that the Dreamliner's fly-by-wire technology: ... optimizes the shape (or 'camber') of the wing automatically to save the most fuel.

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.

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.

MORE DETAILS

The Dreamliner's distinguishing features include one engine under each wing, swept wings with no winglets, two 4-wheel main landing gear, a sleek pointed nose, and noise-reducing chevrons on its engine nacelles. Also, the 787 does not have winglets or sharklets, which are used on the similar shaped Airbus A350.
