Is This Normal On A B737-600? ( Video)

Hi everyone. I recently travelled on a SK B737-600 and after some 20 B737 flights I saw this for the first time and was thinking if this shaking is actually normal on a B737 in general or on other aircrafts. I was not scared or so, just curious because I have not seen something like that before.

Any info is appreciated.

Thanks!

I'm not an expert but it doesn't look unusual. I have seen that sort of shaking a few times. The canoe in the film is pretty close to the exhaust.

I'll let the experts correct me if I'm wrong.

Actually it was only shaking while the flaps were out. During cruise there was no movement. I am always excited to find something new about A/C's. Big grin

Were the spoilers deployed ??

These can have a significant effect on vibration. Most pax I talk to assume that it's turbulence when they are deployed !

No not yet. As you can see we were not that high anymore ( approx. 4-5min before touch down) but I saw it also on the ground while taxing for departure.  Smile

See this video a little time after I took the first one. Here you see more of the wing but nothing shaking anymore.  Smile

You are not allowed to use spoilers once flaps are higher than 10 degrees on the 737... Only on ground after touchdown...

And for the shaking: not unusual when flaps are extended. The airflow is a lot different than during cruise flight with a clean profile... The air is a lot more turbulent with flaps extended and that makes this thing shaking a bit.
If you have the chance, check out the stabilizer after touchdown of a landing aircraft with a lot of recerse thrust! This thing is shaking like hell then  Wink

Its perfectly normal. There is an open gap between the flap and the canoe fairing underneith, not much of it but there is a gap. It's something that I wouldn't worry about.

Thanks guys! As I said I am always full of joy if I see/learn something new about an A/C. And this was really the first time I saw this.  Smile

The TE Flap Fairing in question has play.

Huh? Certainly no such limitation on -800's.

Nothing abnormal in either video... on any aircraft I've flown or flown on... you see that quite a lot.

The Movement of the TE Flap Fairing does indicate play which can def be detected if moved by hand on the Ground.

Well, at my airline we werent allowed to use the speedbrake when flaps are higher than 10 degrees... Maybe it is different at your airline...

I've seen the same on AVROs. There was also quite a shaking of the flap fairings on taxiing and at take off.


Good day to you sir! Please turn left, your seat is in the first row.
