Can't belive that so much is happening this week.

Something is going on with these some airlines not following instruction properly locked cowling Or Manual book is error or some don't understanding properly turn the locked or something. Hmm.

I watched some mechanics close one once and it does look a little more complicated than most cowls. Man that sucks. Gotta take a good look at them.

There's a known issue with the visibility of the latches on the V2500 cowling doors on the A320 family...BA had quite an incident due to an unlatched cowling a while back. There have been others...

Solution? Maybe mirrors. On sticks!

The other one that was posted here the other day was a CFM56. Though I fully agree with you that the majority have been on V2500s, it seems the CFM56 isn't immune to the issues either. (The issues being mx and ultimately the captain, failing to properly latch and verify the cowls)

Here's the British airways report on that incident..... - very good pictures in it as well

I do not think I would be as composed as the person filming was. I would be pulling a horshack

Not as serious hopefully, but this brings back memories of the belly cargo door latching issues with the DC-10. Are we just looking at sloppy procedures on the ground or should Airbus be looking at a redesign of the latching mechanism to make it foolproof?

Both!

One of these days one of these departing cowls will do some serious damage to the tail surfaces, possibly with catastrophic results, and voila! There you have it, a wholly preventable accident.

Looking at the Pictures (page 3/4) in this report, I am actually baffled how clearly visible the unlatched condition actually was. The gap on those cowling doors is obvious, and even the open latches are not that hard to see even from the other side. That walkaround must have been very superficial.

Questions to the mechanics:
After all those events, checking the latches must be some kind of checklist-item which must be signed?
If this is the case, obviously some (very few) mechanics sign up checklist items blindly which they actually didn't perform. That's a worrying thing to think of from a passenger's point of view.

Maybe, but all you have to do is get up to the engine and bend over and look. The latches on our fleet are painted bright orange on the sides so if it isn't latched it is obvious.

At my carrier any time they are unlatched it is a written up in the logbook as an open item until they close them and sign it off as closed per the maintenance manual procedure.

And Airbus hasn't redesigned this... why? It's actually a regular occurance at this point.

Actual ATC recording available here. Frustrating, if you can imagine for PF on GoCat 2638.
Take a listen and you will know why.

From the AAIB report - A redesign is currently going through certification. The proposal is that the latches will be locked with a streamered key that can only be removed when the latch is locked. There is also now the option of having viewing ports on CFM engines to check oil levels without opening the covers. (Subject of course to the airline specifying them).

The NEO will have electric latch proving which would trigger an ECAM memo in the cockpit.
