Default SWA Loses Engine Cowling departing Denver

https://youtu.be/GBQkk4RcidA

Unclear if it was a birdstrike or not. The crew opted for a no-flap landing since they thought the slats may be damaged.

On landing you can see parts of the cowling ripping loose.

That would be a pretty big bird to knock all of the latches open...

This will probably come down to what it looks like: Mx left cowl unlatched and pilot didn't bend down far enough to see them.

Sourhwest for a long time did not have pilots doing walk arounds. I know part of that changed but not sure they require it every leg.

If you don't get low behind the engine you're probably not seeing all the latches. Front dip only doesn't see the last couple of latches.

I personally like to make eye contact with each latch, whatever that takes. I also like to see daylight through gear pin holes. Just not on the guppy nose wheel, not getting that greasy lol.

This is what Quality Control is in a pilot's walk around. Anything else could be as bad as not tracking and verifying door plug bolts removal and reinstation on the factory floor.

I agree about eye contact. If you're not dipping on the front and back, even on w/b's, you're not seeing every latch. Nose gear pin hole? Doesn't matter, I'm seeing the gear pin hole empty. Guppy nose gear is easy, some a/c require you to get on your knees. Oh well, if that's what it requires so be it.

Anyone remember the British A319 that had BOTH cowlings pop open. Kind of hard to not squirm in your seat at that interview.

Every time I've called MX out for this, they've told me it was fine.

Without irony, you could do worse than mandating MX inspect the cowl latches at MX stations.

This may already unofficially be the case.

Alternatively, a better design may be in order.

Is this a "thing" on Airbus fleets/engines?

The Neo’s have proximity sensors located at each latch to monitor the fan cowls position for PW1100 or LEAP-1A engines. An ECAM will display ENG1(2) FAN COWL NOT CLSD caution if the fan cowls are not properly closed. The CFM LEAP-1A engines also include a mechanical prevention flag to warn ground/flight crew if the forward latch isn’t closed.

It's a 'thing' on any engines cowlings that aren't verified closed. Bets me if this event was due to unfastened cowl latches or some other failure.
