Fatal Florida Learjet Crash Linked to Risky Decision Amid Storm

Several crucial human errors may have led to Sunday’s horrific Learjet crash in Florida that killed all nine on board, according to aviation experts.

The doomed $2 million aicraft, en route to the Bahamas from Texas, was flying through a storm when it suddenly stalled, likely between 35,000 and 37,000 feet, and began plummeting before crashing and exploding in a fireball near a trailer park in Palm Beach County.

Authorities are still investigating the cause of the tragedy, but aviation expert Justin Crabbe noted to The Post that the jet’s pilots chose to fly through a dangerous storm — then attempted a risky escape that may have doomed them.

“They certainly should have gone around [the storm],” said Crabbe, a veteran pilot and the CEO of Jettly, a charter-flight booking platform that actually had the Sunday’sLearjet 60 in its listings.

“[Air-traffic control] gave them the flexibility to deviate around that weather,” he said.

The expert said he doesn’t know why the pilots didn’t but suspects they were just eager to get to their destination, the Bahamas. On board at the time were the two pilots and their passengers — a millionaire tech entrepreneur, his wife, their two little kids, two adult friends and the children’s nanny.

“It’s a theory called ‘get-there-itis,’ and flight schools teach you this very early on,” Crabbe said.

“It’s a risk factor. You have to sit back as a pilot and understand what is pushing you to do this trip, this maneuver, this journey in a way that may compromise the safety of the flight.”

The plane’s co-pilot — 20-year-old Nathalia Filgueiras — requested and received clearance at 35,000 feet to ascend to 37,000 feet, above the foul weather, after reporting sub-zero outside temperatures and ice forming on the jet’s hull.

Ice is bad news for planes. It messes with the way air flows around the wings and makes it harder stay aloft. Many planes are equipped with de-icers, but ice can build up incredibly fast in the wrong conditions. The Learjet involved in the crash had a de-icer.

But trying to fly out of the danger may have finally doomed the plane, Crabbe said.

“They tried to ascend to get to clearer air, which may have been one of the contributing factors toward accelerating that stall,” he told The Post.

When a plane’s nose rises, it increases the “angle of attack” at which the wings meet the oncoming air. When the wings are covered in ice, they work harder to achieve lift, and the angle where a plane stalls out lower than normal.

Crabbe said that at that point, the pilots were stuck between two bad options: Ascend and risk a stall or dive further into the storm and risk even more ice buildup.

The expert noted how much pressure would have been on the pilots at the time.

“It’s extremely easy to say this from the ground and from a position of safety,” Crabbe said of the options.

The crash killed 44-year old entrepreneur Adam Robinson, his wife Helen, and their tots Emma, 4, and Charlie, 2 — as well as friends Rachael Reed and Charmi Fehr and nanny Anita Maria Apellido Cetina.

Even the jet’s last-ditch ascent — had it succeeded — may not have accomplished much: The plane was flying through an unusual convective storm system that was nearly 50,000 feet high, according to NOAA data.

“This was kind of the perfect storm of trouble,” said aviation lawyer Zachary S. Gorwitz of Podhurst Orseck, which investigates and litigates air crashes.

Ascend and try to go overtop of the weather by increasing the angle of attack which might aggravate, or trigger, the stall on one or both wings.

“You had turbulence. You had icing. You had precipitation. And you had incredibly tall thunderstorms that seem to have formed very quickly,” Orseck told The Post.

Once the plane started nose-diving, there would have been little the pilots could do — especially as the aircraft seems to have started breaking apart before it hit the ground.

“At that point, I’m sure the pilot was trying to pull back on the controls and get the nose up, but I’m sure at that speed and that angle, it just wasn’t possible,” Gorwitz said.

Whatever the cause or causes of the crash, he said he doubts they include a young, inexperienced co-pilot — even though the terrified Filguerias was the one speaking to air-traffic control.

“The fact that this 20 year co-pilot was the one on the radio suggests the pilot was at the controls,” he said.
