You know the folks over at Boeing have to hate the “d” word right about now. That word, of course being “delay.” The Boeing 787 and 747-8 programs have been taking turns announcing new delays. Since the 787 team announced the last delay, it was inevitably the 747-8’s turn.

Delays look bad and they cost money, but they occur for good reason. Even though the new Boeing 747-8 might look very similar to the Boeing 747-400, there are a lot of changes and of course Boeing wants to make sure the aircraft is fully prepared before first delivery.

The most recently 747-8 Freighter delivery is caused from low-frequency vibration in certain flight conditions and an aileron actuator not performing correctly. These won’t require any structural changes, but it will delay certification testing.

“We understand the issues encountered in flight test and are working through the solutions,” Pat Shanahan, vice president and general manager, airplane programs, for Boeing Commercial Airplanes, said in a news release. “We recognize our customers are eager to add the 747-8 Freighter to their fleets, and we understand and regret any impact this schedule change may have on their plans to begin service with the airplane.”

Although the Boeing 747-8 first delivery to Cargolux is being pushed to mid-2011, Boeing states this change should not have a material impact on their 2010 financial results. Boeing also plans to add a fifth Boeing 747-8 to their test fleet.

One a more fun note: On this day in 1968, the very first Boeing 747 was rolled out of the Boeing factory in Everett (photo).

New British Airways Boeing 747-8F at Paine Field

New British Airways Boeing 747-8F at Paine Field

Late last night I got word from Jon Ostrower (aka FlightBlogger) that a nicely new painted Boeing 747-8 in British Airways colors was out in the open. So, this morning I headed over to Paine Field (KPAE) to check it out. I found her, but it wasn’t so easy. First she was parked a bit off from the rest of the Boeing 747-8’s and she is not in full British Airways livery. She is painted all white with a blue belly.

I was also able to check out the other Boeing 747-8’s sitting, waiting to take to the sky.


Update: BA has announced it is updating its fleet of Boeing 747-400F with new Boeing 747-8F’s and will be leasing them through Global Supply Systems, which is 49% owned by Atlas Air. On the press release BA states, “It has also been agreed that the new 747-8fs will be delivered in British Airways livery and incorporate the British Airways World Cargo logo.” Flight Global reports that they will be wet-leased for five years by GSS.

Last Tuesday a new Cargolux Boeing 747-8 took off from Paine Field to continue its test flights and unfortunately I wasn’t able to make it. Luckily two awesome guys from Portland, OR,  Alex and Russell, were able to get up to Everett, WA in time to watch her fly. Russell got two amazing photos (see larger one of the one above and also a second one) and Alex was able to get a video of the Boeing 747-8 taking off.

A while back to celebrate the Boeing 787 Dreamliner’s test flights, I posted Ten Interesting Facts about the Rolls-Royce Trent 1000 Engines. Now that Boeing 787 ZA005 with GEnx engines are flying as well, I find it only fair to give 10 interesting facts about them:

#1 GE estimates the GEnx engines projected to be sold in the next 20 years will emit an about 77 million fewer tons of greenhouse gases than older comparable engines.

#2 The GEnx engine will remain on wing 30 percent longer and is 30% quieter than comparable engines in service today.

#3 The GEnx-1B for the Boeing 787 Dreamliner has a fan diameter of 111 inches and the GEnx-2B version for the Boeing 747-8 has a fan diameter of 105 inches.

#4 The GEnx engine has 18 fan blades, which is about half as many as GE’s CF6 engine.

#5 If an airline were to replace 20 of 200-to 300-passenger aircraft with next-generation jets powered by GEnx engines, it would save nearly $37 million in fuel costs annually, based on jet fuel costs of $2.50 per gallon.

#6 The GEnx engine has one of the highest pressure ratios – 23:1 that sets the high pressure compressor apart from other engines.

#7 By using GEnx engines, that same fleet could save nearly 500 million gallons of jet fuel each year. Enough to fly more than 12 million people from New York City to London on Boeing 787 Dreamliner jets.

#8 The GEnx engine is the only choice on the Boeing 747-8 and is one of two choices on the Boeing 787.

#9 The engine has composite fan blades with titanium leading edges.

#10 The GEnx has a fan bypass ratio of 19:2, which also helps reduce noise.
