A passenger plane carrying 62 people crashed on the outskirts of São Paulo on Friday afternoon, killing everyone on board, according to Brazilian officials. Dramatic footage from the scene showed the plane’s fall and its destroyed fuselage in flames on the ground.

“There are no survivors,” Ana Cândida Briski, communications director of the nearby city of Valinhos, told CNN, adding that there were no ground victims.

I just saw this news story. Awful! You can in the video, the plane just drops in a flat spin. What leads to that? Any pilots that can answer that?

Loss of control Accident ATR 72-212A (ATR 72-500) PS-VPB, Friday 9 August 2024

A Voepass Linhas Aéreas ATR 72-212A (ATR 72-500), performing flight PTB2283, became uncontrollable and crashed near Vinhedo, São Paulo. All 58 passengers and 4 crew members perished and...

have seen someone speculating that critical components may have frozen over, but the ensuing aerodynamics talk was above my understanding.

Oh how awful. Heartbreaking to imagine how terrified they all must have been!

You can hear the engines running.

I can’t even imagine what those final moments were like.

What causes a spin is a stall. What causes a plane to stall is when the wing exceeds the critical angle of attack and looses lift. When the airflow over a wing decreases, the angle of attack needs to be increased to maintain lift. When the critical angle of attack is exceeded the wing no longer produces lift and wing stalls. If the pilot does not or cannot recover from a stall a spin can develop.

Icing conditions can increase drag and decrease the efficiency of the wing and cause an increase in angle of attack to maintain lift. My guess is this plane encountered icing conditions and the build up of ice on the wings, tail and maybe propellers caused the plane to stall and become uncontrollable.

While training we practice recovering from stalls, which is pretty easy, and discuss spin recovery, since most plane are not certified for spins. But if there was so much ice on the wings and the plane would not fly, it would be impossible to recover from a spin or a stall.

How did it drop 13,000 feet if maximum altitude is 10,000 feet?

It can fly a maximum altitude of 10,000 feet with a maximum speed of 316.9mph.

The aircraft was PS-VPB, a 14-year-old ATR72-500, according to FlightRadar24.

Data from the flight tracker shows the plane lost 13,000 feet in elevation in under two minutes during the final moments of its ill-fated trip.

It appears that the plane had been at cruising altitude of about 17,000 ft when whatever happened occurred. Is that an altitude you might typically see icing? I see from the video that it was a cloudy day in the vicinity.

The same plane was experiencing issues the day before with no air conditioning. Perhaps an electrical problem.

Journalist Daniela Arbex shared on her social media videos of passengers on a Voepass flight, where people were suffering and having a hard time due to the heat, as the aircraft had no air conditioning. Registrations are by last Thursday (08)

After the disclosure of the tragedy that occurred in a Vinhedo this Friday (09), Arbex revealed that he had flown in the same plane that crashed in the interior of São Paulo, a day earlier. “I just learned that the plane that crashed is what I was yesterday and I filmed people having a bad time. I am shocked ! ", the journalist wrote in the original post.

“It was terrible. A passenger came to take off his shirt. Another one, who was an armchair in front of me, had a bad headache. People were shivering for air. (... ) For the third time the company aircraft had problems both in the SP stretch and the connection to Mines. Me and other passengers questioned the aircraft. The answer was that 'air didn't work on ground, only in the air', which didn't. Last time, the excuse was that the air needed maintenance," Arbex revealed.

Finally, the journalist deeply regrets the tragedy and questions the condition of the company aircraft.

Red bolded mine.

If it needed maintenance... it shouldn't have been flying.
Period.
The airplane company should've grounded it.
Not sure yet what the cause was.

Utmost condolences to the family members of all who perished.
Awful to not even get to say a final 'goodbye'.
Rest in peace, passengers and crew.
Omo.

Thank you!!

And, in case anyone is geographically-challenged like I am, it's currently winter in Brazil. However, the temperature is still quite warm. How would ice on the wings develop in a warm climate?

The air is quite chilly at the height at which most commercial aircraft fly—I believe people who attempt to “stow away” in aircraft wheel wells are often discovered frozen to death. This New York Times article says that ice developing on a plane in flight is a known problem, and most commercial aircraft have anti-icing systems to mitigate this danger.

looks like it just barely missed some houses so hopefully no one on the ground was killed too

The temperature on the ground can be warm, but the temperature decreases by 5.4 degrees Fahrenheit for every 1,000 feet in elevation.

The plane was flying at 17,000 feet above sea level. The elevation at São Paulo is 2500 above sea level. So the temperature at 17,000 feet would have been be 78.3 degrees below the temperature on the ground. Unless it was 110 degrees on the ground on the day the plane crashed it would have been below freezing at a flight level of17,000 feet.

Any time a plane is flying in cloud and temperature is below freezing icing can occur.

Airliners typically fly at around 36,000 feet and the temperature there on a 70 degree day would be around 124 degrees below zero.
