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 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 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 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.
Therefore, the ERJ135/140/145 members of the family are among the safest airliners in history. The Airbus A340 is also one of the safest, with no fatal accidents involving any of the 380 units since its introduction in March 1993.
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 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.
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.
•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).
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.
In addition, the 787 is much quieter than other aircraft, so pilots can enjoy a quieter cockpit. The 787 also offers improved cabin comfort for airline pilots. The Dreamliner's cabin is pressurized to a higher altitude than conventional aircraft, which makes it easier to breathe and reduces fatigue during long flights.
The Boeing 787 Dreamliner has revolutionized flying for both passengers and pilots. Taking a leap into the future from its predecessors, the designers incorporated a number of new features that make the Dreamliner one of the most fuel efficient and comfortable aircraft in the skies.
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.
