The electronic edition of this week's (5/2/06) Flight International is reporting that Tim Clark says Airbus faces "huge hurdles" to meets it April 2007 target to deliver the first Engine Alliance-GP7200 powered A380, of which EK is the launch operator. "I dont believe for a moment it won't be tough," said Clark. "So far, it's so good, but cabin integration is an enourmous challenge. If it is looking to go beyond that time we have asked them to be as candid as possible with us. But nothing would surprise us."

Last week EK confirmed that senior managers had visited Toulouse in April and "they confirmed we will receive our A380 in mid-April." Publicly Airbus will only commit to a "second quarter" delivery for the first EK aircraft.

It's going to a very large task. Being that a GP-7200 powered A380 hasn't even flown yet.

The thing that I wounder is who's mainly at fault. Is it Engine Alliance or Airbus? I've read that the main issue is unseen problems getting the engines integrated. What hasn't really been covered is who's side the Tech issues are on.
Well who ever is at fault will surly have some major penalty's.

what was the original time frame for testing of a GP-powered example?

I'm no engineer but I can't understand why it would be harder (if it is) integrating the GP7200 than the Trent 900. Any answers?

Engine Alliance politically is a different beast then RR. That means that integration might be more difficult both poltically.

Random question, did Airbus ever state when they intended to start the GP tests?

The engines were hung on the airframe in February, so its got to be soon I think. While not being an aerospace engineer, I would highly doubt it would be a hard task to certify just an engine in 9 months.

The FAA granted the engine its certification on 29 December 2005.

I meant internally - time from the RR engines being hung on the airframe to first flight was around 4 months, so this could be similiar.

what does politics have to do with engines being hung on a wing?

It's the airframe/engine combination that has to be certified. This will entail re-doing a number of the test conditions performed for the Trent 900 A380 certification.

However, there will be addition flowtime because the EK interior must also be certified before the airplane can be delivered. After all, individual airline interiors were given as the primary cause for the late delivery to SQ.

Yes but it certainly doesnt mean the same amount of time the RR engines have been flying, and thats only just a year now.

With more than one airframe for EK currently completed, the interior and the engine certifications can be done in tandem.

Its just under a year until the deadline EK have publically stated, so I dont think we need to engage in any rumour mongering just yet.

No airframe slated for delivery to EK is part of the flight-test program, MSN002, 004, 007, 009 will all be delivered to Etihad. MSN007 & 009 will be re-engined to Roll-Royce before delivery. Oddly, 007 starts off with RR, with a switch to GP this summer, and switch back to RR before delivery to Etihad.

Without the airframe/engine combination in the Type Certification Data Sheet, Interior certification can be difficult to achieve. It is not a given they can be done in parallel.

Engine failure conditions can induce loads in interior fittings that must be accounted for in their certification.

The problem is, the cabin has to be installed first - so it'll be something like fly to XFW, fit cabin and then do engine and cabin trials (if they weren't done before the ferry to XFW).

Hardly a rumor, as it comes from the mouth of the CEO whos airline we are talking about.

Yeah, but Clark is one of the most vocal, manipulative CEOs out there. I've never seen one guy so loud about so many things, making so many demands publicly. I know he controls a lot of lucrative orders, but it's getting kind of ridiculous.
