how do they have that much ultrasound equipment sitting around?

[mocat]

Great, now we are going to get a bunch of new fatigue regulations. (Not for at least 10 years though because the FAA is super slow at implementing new regulations.)

this is your wheelhouse.  this wasn’t an airframe failure, it seems pretty obvious that the engine failure was due to a lack of following existing maintenance guidelines, no? this is the first fatality on a us airline in 9 years, planes aren’t dropping from the sky

My understanding is that the engine manufacturer had issued a SB (Service Bulletin) but the FAA had not yet issued an AD (Airworthiness Directive), so without an AD it is basically just a suggested from the manufacturer, not a legal requirement. EASA (European Aviation Safety Authority) had made it mandatory for EASA registered aircraft just last month.

The SB told them to perform an ultrasonic inspection on the fan blades to inspect for potential fatigue cracks before they became critical size that would fail in flight.

image that, a downgrade airline doesn't GAF about safety unless they're forced to

The FAA issued an emergency AD requiring inspection of all CFM56-7B engines within 20 days (from April 20) so try not to fly on an airplane with that engine before May 11.

About to get on a 737 irl rn, how do I know if it has the pos engine or not?

Well it's like one of the main NDI methods used regularly to inspect aircraft.

99% chance it does.

Non-downgrade airline tho

After a notice of proposed rulemaking (NPRM) was published in August 2017, American Airlines voluntarily began inspections of CFM56-7B fan blades under the guidance proposed in the NPRM.

Currently on shitty airline 737 inbound for KC, T’s and P’s appreciated.

Honest q, how come all sw planes aren't grounded rn?

[Phil Titola]

Guess but it's only a very specific engine.

I flew on 4 SW 737's this weekend and lived to tell the tail

[420seriouscat69]

When was the last time Southwest had an accident before this one?

[420seriouscat69]

Lol. Downgrade Southwest has always been safer than the bigger downgrade of Delta

Same exact thing happened in August 2016 and they didn't do anything about it, but other airlines did. Like all gE'ing aside I'm surprised they're able to keep flying w those engines

Nobody died so this statement is very misleading.  Do you understand(really) how many miles/flights/hours have been put on every single one of those model engines?  It’s absolutely astonishing that they can go what they have without incident.  This isn’t like some firestone exploder thing.

[Mrs. Gooch]

I can give a fatigue lesson at a later date, but suffice it to say that the engineers have used hand waving and magic to determine that this won't be an issue until the engine has 30,000 cycles so only engines beyond this need to be inspected.

Beyond that, the FAA has given the operators 20 days to comply with the AD so there are still airplanes with more than 30,000 cycles on those engines that are flying right now.

Yeah but did you see that usatoday airline ranking from 2010?

How many fatalities has Southwest had in their history, dipshit?

Big boeing QA outed.  Also, let’s not forget mocat is a self proclaimed PE engineer, all the while math is obviously something lacking.

you are carrying a lot of water for SWA for unknown reasons.

[420seriouscat69]

Yup. Delta's had more crashes due to this data. This was November 17th when Southwest still had zero, but just agree with him already, guys. Sheesh. http://www.airsafe.com/airline.htm

I think that's exactly what the sw brass said from their plush Dallas conference room in 2017 to the faa

Nothing is unknown here. Chodecat bags on SW and praises Delta because that's who his company is in bed with. Unfortunately for him. He's not safer flying it.

Http with that UI is definitely an up to date trustworthy website.
