Over pilots’ objection, Boeing seeks safety exemption for MAX 7

Boeing asked the FAA to exempt its 737 MAX 7 from certain safety regulations. Without the exemption, an engine anti-ice system defect will keep the jet from being certified.

Wow.

Boeing wants an exemption for a potentially catastrophic defect.

That is simply not acceptable.

OMG!!!

He said the pilot procedure the FAA approved as an interim solution — urging pilots to make sure to turn off the system when icing conditions dissipate to avoid overheating that within five minutes could seriously damage the structure of the nacelle — is inadequate given the serious potential danger.

This would be like asking me to remember to turn off the defrost for the outside rear view mirrors on my truck. I almost never remember to turn them off until I look down a couple of days later and see that the defrost is still on.

Alaska launches temporary grounding of 737 Max 9 fleet

It was like 10 weeks old. I'm not sure it would have even been touched by AA maintenance crews. Apparently they followed maintenance guides and pulled it from longer flights, but not sure why it wasn't checked.

Per the interwebs the fuselage for this plane is almost entirely outsourced. One subcontractor specifically (Spirit Aerosystems) was responsible for installing this panel before the plane left the factory. Spirit's CEO resigned in Oct due to production issues around QC. You’d think Boeing would have their own QC people there checking everything, but obviously the Boeing finance bros think otherwise.

Well then there is this...

Wow! I've only flown them once knowingly, from Seattle to Idaho Springs. At the time, they owned Horizon and the Horizon airframe had problems, so they brought down an Alaska plane and crew for the leg. One other time I had an Alaska crew, masquerading as Delta. I forgot how I found out, but it was a severe shortage of Delta crews after the Atlanta ice storm fiasco. As I left the plane, I just said to the attendant at the door "Thanks Alaska!" She flashed me a big smile...

This article was unnerving...

The really unnerving part is nobody wants to fly on these, but some airlines have already stopped listing them as 737 MAX at booking and just as 737. So, the consumer doesn't even have a say.

I was curious how it attached and found this. There is no mechanism to lock it in place like a regular door. No way someone missed all those bolts either. This has to be some design or material flaw…

Missing part of Alaska Airlines plane is found in Portland, NTSB says, as new details emerge about the aircraft | CNN

Talk about a needle in a haystack. Also new details in there about the previous pressurization warnings, those WERE checked by AA maintenance crews. They also didn't get the cockpit recorder in time and it overwrote itself due to the 2hr loop settings.

That seems like an extremely short loop and they should have some way of preserving the record in cases like this. Maybe it's a Boeing "feature" instead of a "bug"...

 

[TIDE-HSV]

A little more from CNN - Alaska Airlines could have "pulled" or retained the cockpit recording, if they had acted in time, but they didn't. The FAA has a new rule proposed, only for new planes, that the recording cycle be 25 hours, but the pilot's unions are opposing it. I suppose the same reasons as LEOs oppose lapel cameras...

😲. I take back what I said about no way someone didn’t tighten all those bolts.

https://www.cnn.com/2024/01/08/us/alaska-airlines-plug-door-found-investigation-monday/index.html

Yep. I’ll never willingly fly on one of these. I’ll turn around at the gate if I have to. So it’s going to end up being these weren’t properly secure/tightened and most likely vibrated off during normal operation.

Did they even tightened it enough to compress the lock washer?

 

[NationalTitles18]

Our first leg Wednesday is on a Max8. The remaining legs (one more getting there, two coming back) are on the Embraer or 737-800 (the old style). We are flying United. Hopefully, there are no similar problems on the Max 8.

These mid cabin door that were plugged have four locking bolts that are designed to prevent the plug from being opened. Question is, were these bolts properly installed. Video is a bit long, but goes into detail about the door's installation.
