"I was aboard this aircraft. The take off was fast, rather quick and felt short. Then we pitched down and banked right (left wing up) and then left (right wing up) and the back felt to skid out sideways, I was in the window seat just behind the left wing. Then it felt like the pilot pulled the aircraft up manually. He continued to make very strong left and right banks while in the air before we circled back to JFK.
Sounds like a wake encounter.

Wake encounter in such crosswind?! Sounds like pisspoor piloting skills to me.

I would think that some marks would exist if true and haven't seen anything 'leaked' yet. Pics of wing damage are available.

SLF here. Just wondering if perhaps a wake from an aircraft departing 31R could have propagated downwind to 31L given the breeze. I've hit by more than a few wakes while sailing close to the runways in BOS, they do seem to sink fairly efficiently.

​​​The two parallel runways mentioned are just too far from eachother with lots of obstacles, like terminal buildings, etc. in between.

I hope AA isn't again training in aggressive use of rudder pedals in turbulence as before the AA 587 crash.

Sorry, I dont see the crosswind details anywhere.

Would also have to see where at this airport the crosswinds are measured.

The problem seems to be establishing just what the manufacturer stipulates, and how strictly that's interpreted as SOP.

A pal of mine had a friendly chat with a boss about holding the side-stick back slightly during the deceleration run. Such a small issue; a hangover from the old days. So what of crossing the controls on take off? If allowed at all, I'm sure it wouldn't be great handfuls of stick and rudder like the DC3 days.

There was a discussion a year or so back about crossing up upon landing. I was pleasantly surprised at a few more experienced posters being very for this technique. This was after a near wing-tip scraping landing with a major thump when the starboard wheels came down.

Wake encounters are pretty obvious and distinctive on a DFDR review.
Not suggesting it was (or wasn't) a wake encounter, but they should readily be able to tell fairly quickly.

Handling skills are now tertiary to what managers are looking for in a newly-hired pilot. There is a presumption - by HR types - that pilots should first be customer service agents, then pilots. Flying can be trained after the fact. That’s their opinion. Anything goes to be the most PC company now.

TWR wind was 010/17 prior takeoff roll.
Anemometers are placed along all RWYs, although I'm not sure about their spacing or number.

Not a player in this case:

JFK 03/759 JFK RWY 13L/31R CLSD 1904010300-1911162200
This NOTAM in secret coded format says that runway 31R was closed when the mishap occurred.

The aircraft taking off on 31L prior to American 300 was Envoy 4077, an EMB-135, about two minutes earlier. Just before AA300 started to roll (in more than one sense) Avianca 244 was landing on 4R and Delta 408 was taking off on 4L, both A330-200's:

Well, I dont think an ERJ caused a wake...nor a mild crosswind...
dragging a wing for a bit and taking out a sign....damn.

Finished work early? NOTAMS for closure, not for open!
So many crane obstruction NOTAMS hanging out there...

Reported TWR wind was 010/17. Anyhow even 5 kts of crosswind is enough to highly reduce the effect of wake caused by the preceding aircraft, if any.

Actually, a light crosswind can actually make it worse. Wingtip vortices move slowly outward away from the departure runway. A light crosswind can effectively hold the upwind vortex on the runway. Not saying that's the case here, but it's something to consider when judging your separation needs.
