Boeing Dreamliner 787 deliveries delayed due to production flaw. Boeing faces another setback with the 787 Dreamliner due to a newly discovered production flaw. In a statement issued on June 6, 2023, the company warned that this could potentially delay the delivery of 90 jets currently in its inventory?.

Boeing's deliveries of 787s remain halted due to quality and production issues, including those related to gaps and skin flatness between fuselage sections that fail to meet precise tolerances, Boeing has said. Shimming is one method of addressing skin-flatness problems.

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.

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.

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.

The two aircraft are the smallest variant of the Dreamliner family, being -8s, and have been in storage since May 2019. Why are they being scrapped? Norwegian placed these two aircraft into storage when Boeing 787s with Rolls-Royce Trent 1000 engines were grounded due to engine fan blade corrosion.

Over 70% of the value of Boeing's new 787 Dreamliner was provided by outside suppliers, including engineering work in USA, Australia, France, Japan and Italy. This was a much higher share than in the previous airplanes of the company where less than 50% was outsourced.

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.

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.

Boeing's Sanderson isn't defending the delays, but stresses that “All 787s in service and in our inventory are perfectly safe to fly.” The planemaker sees a silver lining with learnings applied to build even better 787s and new aircraft like the next-generation 777-9.

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.

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.

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 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.

• 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).
