I wonder what a full X-ray of both airbus and Boeing carbon parts would show

Cracks in main spars I would think are more common than you would imagine. When I worked Nimrod R1 (de-haviland comet) all of the planes had plates and reinforcement on the wing spars and associated root box. They were all low hours.

Current aircraft I fly on only 1 out of 6 hasn’t had spar repairs carried out. There all very low hours compared to physical age again. It’s the whole point of schedule maintenance and NDT.

It’s not good I agree but I doubt it’s as uncommon as most people would be aware of. The military aircraft I have worked/flown on are all low hours compared to physical age. There all well over serviced and maintained.

Civie aircraft are flogged to death with minimum maintenance, especially short haul aircraft doing multiple takeoff/landing pressurisation/ depressurisation cycles. That really does hammer the airframe. Flying along straight and level is really minimum stress levels.

Whilst I was at airbus one of the delaying factors on the 380 was the agreement of how to inspect the wings and tail without issuing expensive scanners

Trouble with cf, it goes from structure to broke with very little notice.

Has anyone watched the Al Jazera documentry on Boeing?
Talking to a 737 pilot today and he recomended it.

Boeing prediction for return to flight of 737 max.

More chance of brexit

Will be interesting to see SouthWest's position given they drove the common type and no re-training but now employ the ex-Boeing guy involved in textgate.

Didn't they originally predict April-May of this year? (apologies if it's in the article, I'm cooking supper so didn't read it)

Qantas have found issues on an aircraft with 27,000 cycles (FAA mandated checks on NGs with 30k cycles and above).

Who can trust the FAA?

No need to. O'Leary says it's safe so we're all good.

Boeing?

Or -

"Disgruntled ex Boeing Employee describes a very normal quality control/manufacturing finding, of the kind that happens daily and was dealt with in the normal manner"


I'm not saying its right or wrong, however take anything like that with a pinch of salt.

a 25% failure rate is not acceptable, I doubt this is a disgruntled employee other than his levels of gruntledness were worn down after repeatedly trying to raise the issue that could lead to passenger safety issues.

I generally distrust Boeing and their approach to safety and welcome hearing more about this fault.

Doesn't sound right.

Emergency systems are installed, but won't be operated, they will be tested to ensure they are "ready" to activate if required.

I remember an issue i had with a safety system which operators working in a manufacturing facility where it was rather warm were deploying emergency ladder systems, obviously with no idea / training how to properly pack away without impacting it's ability to deploy.

Remember, aircraft parts are made by the lowest bidder, it doesn't specify the issue, so i wouldn't like to guess, but having worked in aerospace (commercial, space & military) in supply chain quality for 10+ years, nothing would surprise me.

If you activate the bottle it'll need replacing after the test (as it's empty), so they can't be "fully tested" as such as the bottle would need replacing after every test, leading to a new test on the new bottle, leading to an empty bottle and new bottle being fitted in an endless loop - you would never be able to finish the job off.

So instead they test just the "release" mechanism to prove that, should it be needed for real, the mechanism would work and the bottle "should" work too!

Most of the oxy testing I've done uses a chemical reaction to self generate Oxy for about 5 mins only (enough for the plane to descend to 10k ft) rather than use a "bottle" system like they're saying the Dreamliner uses, unless of course they're getting mixed up which, being the press they may be!
