Interesting video of an engine nacelle getting loosen on take off on a JJ flight two days ago (5/19). Apparently an A320. People get quite desperate during the event, but the airplane returned to the airport with no further inconvenients.

Wow this is pretty intense. I have seen pictures of this happen on previous incidents but never such a great quality video.

I work in aircraft maintenance and this situation brings to attention the key importance of latching panels properly.

It looks like the latches on the fan cowls were not latched which is surprising as fan cowls require a duplicate inspection and should be looked at during predeparture walk arounds by engineering staff and flight crew.

That was flight JJ3317 (NAT - GRU) and the A/C was an A320. The plane took off @ 07:36 local time, and after circling Natal to loose fuel landed without incident in NAT at 08:42. There were 166 PAX + crew on board. According to passengers interviewed, there was some panic on board...

Local paper Folha de São Paulo brings a photo of the engine after landing:



One more incident on TAM already tarnished ill fame...

Another pic of the engine, taken by the guy who made the video:



According to him, the engine "exploded" (not true - it is clear that the nacelle was not latched properly) and the expelled metal parts hit the upper part of the fusellage.

Looks like someone on the ground at NAT opened the engine nacelle and forgot to lock the latches after closing it.

Apparently it was PR-MYP which was delivered less than two weeks ago from Airbus.

I would expect so! That is a scary incident.

Looks like some damage to the top of the fuselage.

Photo looks much like these earlier A320 incidents.

The A320 design is known for this issue; AirTran dealt with it a few years ago.
It can happen on any airplane, but supposedly the design of the cowl latches is such that it's more difficult to discern an unlatched cowl. Never having worked on 320's, I can't comment.

But- like I said, it can happen on ANY airliner, and we should all be doubly diligent during walkarounds!

It was a Ryan International a/c operating for AirTran.

If I recall from a previous thread not too long ago regarding a similar incident, haven't some airlines made modifications to their nacelle latches so that it is easy to see that the latches are not closed?

TAM's maintenance issues are very, very infamous in Brazil, with this one on Folha de São Paulo's pages will only bring more fear...

Question: why would both doors blow open? Do they latch to each-other or to the underlying structure?

When that panel let go it sounded like someone got slapped.
Even though we look out the windows and see nice clean air while flying, the wind out there is quite violent. Just watch how those parts were just ripped apart.

Most fan cowls I have seen latch to each other along their bottom (non-hinged) edges. There may also be smaller auxiliary locks on the side of the fan cowl panels that latch into the surrounding structure (RB211-524D4).

RB211 combustion case fairings (inside fan air duct) can also be troublesome when it comes to confirming proper latching.

It looks spectacular but it's not particularly dangerous. There's basically no way for the cowl to go into the engine, which would be the real risk, and the engine really doesn't care whether the cowl is there or not.

The highest wind ever recorded in a tornado was 301 mph. Typical flaps up speeds on an airliner are about 280 mph, with cruise speeds well in excess of 500 mph. So it's like being in one of the worst tornadoes ever, except doing it every day all day.

Horrible video description. There was no explosion. I do avoid TAM as they because of their poor maintenance practices.

I don't want to be a messershmit (but I couldn't resist since you're one of my most respected users tdscanuck) but wouldn't it be more correct to say that the wind around an airplane never really gets higher than about 320-350mph. True, the TAS will reach 500+mph as well as the ground speed but with air density decreasing with altitude the equivalent wind (to ground level) would rarely exceed 290kts IAS/CAS equivalent (about 320mph).

In the case of this incident a lot of pax reported an explosion but I'm guessing that must have been the sound of the cowling hitting the fuselage..

Cheers



I love the smell of Jet-A1 in the morning...

320-350 mph effective, yes. I toyed with trying to bring that into play but though that a discussion of IAS vs. TAS might be too off topic.

That said, you're absolutely correct. In terms of force exerted by the wind, it's going to max out around 350 mph equivalent.

This is basic.......People in Maintenance need to know how to latch fan cowls.....

Are TAM safety/maintaining issues real or perceived? I dont recall RG having issues even towards the end. But I absolutely recall that the VARIG maintenance center was great out of Rio and many airlines used it for maintenance as well and was even a revenue stream for them as I had once read in Icaro magazine (biased I'm sure)

But TAM certainly does suffer in Brazil from these rumors - mostly from the disasters at CGH. This video is the last thing JJ needs aired on Brazilian news.
