Airbus A321 loses directional control on takeoff
What could have caused this emergency. Seems a bit strange. Warm weather in an area that does not get snow.....
"X-XXXX an Airbus A321 was operating as flight Flight XXX from Point A to Point B. During take-off roll
at approximately 15 kts, Flight crew rejected take off due to loss of directional control. The aircraft
was brought to a full stop and flight crew declared a MAYDAY. After assessment of the situation
and inspection, flight crew taxied the aircraft to the ramp."

Asymmetric spool up of the engines might be the culprit. As might many other scenarios.
There’s a comedy set of skid marks on the threshold of 27R at LHR at the moment caused by this very reason. It’s usually handling error.

If, for whatever reason, you thought you'd just had an engine fire, uncontained engine failure, etc., would "mayday" not be the correct call to get the appropriate emergency response?
Clearly in this case it wasn't so serious, and was deemed so shortly after the call, but isn't better safe than sorry supposed to be the idea at that point?

Derivation of MAYDAY = "m'aidez" (imperative of "help me" in French).
If one is stuck on the active runway with a problem that can't be solved from the cockpit - there is a certain urgency to the situation. You need ground support ASAP.
A320-class have been known to have jammed nose-gear.

Edited LiveAtc.net tower audio attached as a .zip file which will open on most computers and some tablets and phones.
Maybe the MAYDAY is procedural on a reject at Air Transat.
The captain says that the nosewheel was about 90 degrees to the left. As mentioned above, this cocked nosewheel seems to be a recurring issue on the A320 variants.
She doesn't ask for assistance and exits runway 28L at J8.

A/C: "Mayday,May..."
...a few seconds later...
TWR: "Do you require any assistance right now?"
A/C: "Negative"
If the crew could do it over again, they most probably wouldn't use the M-word again. Training instinct kicking in? Like the crashing 777 at LHR, using the training callsign for their mayday call
And just maybe they had more important things to focus on, than the optimal phraseology?

Anyone considered that he may have called MayDay because he was stuck on a live runway, unable to vacate and maybe, just maybe wanted to get everyone’s attention that something potentially dangerous was going on....
Not that I feel strongly about this but it reminded me that years ago I had an Air France pilot as sim examiner who really wanted us to declare a mayday for any abort. I didn't necessarily agree with him but apparently it's a thing for some people.

Engaging the ATs before engines are spooled up can sometimes result in an engine spooling up much faster than the other one. This can, and has, caused a similar problem on a B757.

Been there, done that. Badly judged "rolling take-off" with TLs stood up before aircraft even close to lined up on runway heading. This then required more tiller input which made it worse. I spent next few months blushing with embarrassment each time I passed the very impressive tyre marks I had left on the piano keys.

Transat pilots are required to call Mayday for any reject. They also fly to various places in the Caribbean and latin america where ATC coms (and efficiency) are substandard and they had issues during rejects (in Cuba): ATC did not understand the words reject/stopping and cleared the other aircraft to land. Consequently the Mayday call is now required to improve the safety especially in these countries (and pilots use it as robots at any destination even if it may not be necessary).

All decisions are correct at the time, in the view of the decider, in the situation, and as understood by them.
With hindsight, decisions might be be questioned, but not concluded unless you were there or have all of the facts leading up to the event.
Re asymmetric engine spool-up, see Airbus article in :-

Note discussion on the effect of crosswind.
