Probably borrowed them to replace the ones holding the engine on.

Screws.

You can tell by the cracking epoxy that fatiguing in this area with missing screws was taking place.

Without understanding the number of fatigue cycles this area has gone through already it is difficult to predict when failure would occur. The good news it was noticed and can be fixed.

That's what I was wondering. Seems odd that four in a row were missing without a common cause. Wondering if some type of flex occured that popped all four out of that location. That section might be weakened even more than it appears.

Don’t pilots walk around the plane before take off to check for this stuff?

Supposedly but I don’t know if they’re looking for things that can’t be seen from the ground.

Yeah definitely DEI.

Planes never used to crash when it was just white men that worked on them…

Ignore the necessary mathematical and logical consequences of reduced safety and enjoy your flight.

Where do you see cracks?

BTW, from a maintenance manager on several different military aircraft, missing fasteners on certain wing panels, especially on the trailing edge, is common, however, I believe four in a row would be an issue.

Anyone here who doesn’t have extra parts leftover when they put their stuff back together should speak up now.




My "extra parts" were initially placed in a large mason jar. That eventually transitioned to a plastic storage bin.

Can you imagine if you saw this and didnt say anything pre-takeoff?

I'd be nervously watching that wing the entire time the plane was in the air.

Comparing the cracks in epoxy along the seam adjacent to the screw holes where they are missing screws versus the epoxy along the seam adjacent to the screws properly fastened. Based on the cracks in epoxy you can tell the region without the screws has been moving...or flexing.

So, my preflight checklist now includes watching the plane from the terminal and looking for issues. Then when boarding, pause to look out the windows for missing screws/wings/engines, and alerting the cabin crew that I will not be flying with them today without those items.

Aerodynamic sealant is always cracked, but I can understand what you’re getting at.

Do you think it’s amazing, or do you think that because of the Alaska Air incident everyone is more aware of their surroundings on an airplane and looking for any missing bolt they can find for the first time in their lives? It’s probably way more common than we think and now every instance will be pointed out, posted, freaked out about, sensationalized for $, flights cancelled to avoid panic and angry customers, and then it will all die down when the next outrage news cycle distracts the masses from the issue du jour

Correct. Proseal, which is the common name for the sealant in the industry will shrink over time and paint losing its bond to it will give the appearance of cracks.
I would be curious to know if the installed screw at the top has lost its torque. Judging by the working smoke trail, I bet it doesn't.
