Just now on the news: A TACA A321 out of the runway in San Jose, Costa Rica. The flight was LACSA 621 arriving at SJO from SAL and YYZ. Visibility is poor in SJO at this time and it is raining like hell. Link just in Spanish at this time:

I wonder if there were any spotters hanging out at La Candela at the time of the incident.. or if the Telenoticias traffic camera at the highway intersection northeast of the airport was facing the runway and caught anything.

My younger bro was on that flight with a bunch of his friends and this is what he said happened:
"'So we arrived a little while ago in San Jose. We're all safe but we had a borderline crash landing. The brakes failed on the landing and the pilot had to crank the wheels sideways in order to stop the plane. The front and side tires blew out, but the pilot managed to keep us from sliding off the runway. They closed the airport for an investigation now. We'e about to go get our stuff and go through customs. Needless to say our adventure trip has started up in full force lol."'
I'm glad that there were no injuries and that it wasn't worse.

Hey, good a*net sources here: a good friend of the captain, someone trained by the copilot, and someone whose son was on the flight. Let's get to the bottom of this!

Strange things can happen on a wet runway if the anti-skid fails or strong control inputs are made.
Back about 40 years ago (1973), we had an EA-3B Skywarrior come off the runway at NAS Cubi Point in an extremely heavy rain storm.
The tower, nor any known witnesses, saw it happen due to the rain, but the plane ended up with the drag chute drapped across the nose and refueling probe. The plane was pointed in the right direction when it stopped, but was about 20 feet parallel to the runway on the right.
The AMH2 found that the anti-skid had failed on the right main gear. Interestingly it did not blow any tires.

Captain Bruno is one of the best and most experienced captains at LACSA. Other pilots and flight attendants at the SJO Hub made public comments on Facebook thanking God no one was hurt, and for him to be the PIC of this flight, because of his high skills and knowledge on the Airbus fleet, which he has flown for years now.
For all of us who have flown into SJO in our rainy season (May through November), we just know how tricky it gets to get in, especially in the afternoons, between the massive rain fall and thunderstorms, and the poor visibility because of the intense fog! This incident however looked like a mechanical failure on landing, although the runway was wet and it was raining like hell at the moment of the touch down! The crew had left SAL for a bigger A321, and continued flight LR621 into SJO.
As a Costarican, a pilot, and a TACA frequent flier myself, I share the comments on Facebook about Captain Bruno and all other LACSA pilots' great skills and knowledge, which prevented yesterday an accident of bigger consequences, like the ones in Tegucigalpa and Sao Paulo! Good job guys!

Quoting tomascubero (Reply 8): seems like brake failure and subsequent tire bursting
Quoting CRFLY (Reply 17): looked like a mechanical failure on landing
Given that I neither have the appropriate background (my field of expertise is real estate and law) nor all the facts, it could be overly audacious to argue with two pilots (not that your relationship to the cockpit crew necessarily disqualifies your arguments) but I have to agree with the following statement..
Quoting RFields5421 (Reply 15): Strange things can happen on a wet runway if the anti-skid fails or strong control inputs are made
Apparently there was some serious hydroplaning going on yesterday.. La Naciónquoted an Air Surveillance Service (the Ministry of Public Security operates a permanent facility on airport grounds) pilot as saying that al parecer, la nave realizó un hidroplaneo. “Como la pista está mojada, el contacto de las llantas con el pavimento se hace más difícil”, explicó — fact is, hydroplaning can delay wheel spin–up, and the anti–skid system needs wheel speed to be activated.
Per the A318/A319/A320/A321 FCTM (NO-160. P 6/12) the A/BRAKE provides a symmetrical brake pressure application which ensures an equal braking effect on both main landing gear wheels on wet or evenly contaminated runway. More particularly, the A/BRAKE is recommended on short, wet, contaminated runway, in poor visibility conditions — however, my understanding is that releasing the brakes (taking over from the autobrake) actually helps regain traction (and reduces slip) by allowing the wheels to spin freely, thus making it easier to stay *on* the runway.
On a side note, it would be reassuring to have a third party —other than AERIS— evaluate the runway surface (macrotexture) condition to see whether it still meets the required friction levels.. we cannot rule out MOPT has somehow overlooked or neglected this important operational safety aspect, considering their nightmarish track record of incompetence.

My personal speculation on what could have happened during this incident on landing at MROC having personal knowledge and experience landing there in those reigning meteorological conditions with a heavy downpour, strong gusting crosswinds on the runway can induce weather vaning of the long fuselage A321 due to hydroplaning of the main landing wheels while normal auto braking and anti skid system are operating when normal reverse thrust is being applied after touchdown to stop the airplane on a flooded and slippery runway.
METAR data suggest the crosswind component for runway 07 was 1 knot at 2100Z and 4 knots by 2200Z.
Quoting av757 (Reply 19): weather vaning of the long fuselage
Notice the pax quoted above describing (in his own vernacular) what he perceived as the pilot having to "crank the wheels sideways in order to stop the plane" while it drifted almost perpendicular to its direction of motion.

The plane involved in yesterday's incident, N566TA was ferried today to SAL as flight LR9670 at 615am... Now I guess Aeroman in SAL is in charge of the repairs (if there is any) and to identify the possible cause of the incident! Best regards to all!

They wasted no time. It took airport crews much longer than that to clean up all the remaining burst tire debris.

Had this incident occured within United States jurisdiction, the NTSB would have done a thorough investigation (which typically takes several weeks) and issued a number of safety recommendations. This being the happiest country on Earth, however, we rely on the airline's maintenance subsidiary to "identify the possible cause of the incident" while the local DGAC sits on its rear end.
