Federal officials stated that ice and adverse weather were significant factors in the private jet crash in Florida that killed all nine people on board. The Learjet 60, en route from Austin, Texas, to the Bahamas, nosedived into a highway near Palm Beach on Sunday afternoon, erupting in a fireball.
In audio transmissions released to the public, co-pilot Nathalia Filgueiras, 20, can be heard reporting "light, clear ice that is manageable and moderate turbulence" to air traffic control. Shortly after, the aircraft entered a thunderstorm cell and experienced a catastrophic dive, descending more than 20,000 feet per minute.
"We have some indication that the aircraft was breaking up before impact," National Transportation Safety Board member Tom Chapman stated, suggesting that turbulence may have contributed to the disaster. Experts cited by The New York Times noted that even small amounts of ice accumulation on an aircraft's wings or engines can severely impact its performance, making it difficult to maintain control and potentially leading to a stall.
"It sounds like the plane iced when they flew through the cell," said Daniel Bubb, a former pilot and aviation instructor. "They thought at first it was light to moderate icing. But then it sounds like it got really severe."
Investigators are also exploring the possibility of pilot error. For de-icing systems to function, pilots must activate them. "The big question is: Were the pilots aware of and were they informed that they were entering into weather conditions that would contribute to ice accumulations?" asked Mike McCormick, former director of air traffic control at the FAA.
Some aviation experts theorize that the pilots may have underestimated the impact of "clear ice"—a type of ice that forms from supercooled water droplets and can significantly affect flight controls. Attempts to correct for turbulence by climbing might have induced a "violent pitchover," potentially leading to a tailplane stall.
Flight-tracking data indicated the jet plunged approximately 27,000 feet in about one minute before its signal was lost. The NTSB confirmed that a portion of the jet appeared to have broken off before impact. The crash occurred about eight miles from President Donald Trump's Mar-a-Lago resort, though officials stated there was no indication of any connection.
The victims have been identified as pilot Jeffrey Gregory, 55; co-pilot Nathalia Filgueiras; tech tycoon Adam Robinson, 45, his wife Helen Sharp, 40, and their two young children, Emma, 4, and Charlie, 2; Robinson's friends Rachael Reed and Charmi Fehr; and the children's nanny, Anita Maria Cetina.
Federal Aviation Administration records show Gregory held an Airline Transportation Pilot certificate with ratings for multiple jet types, including the Learjet 60. He possessed a First Class medical certificate valid until June 2026 and had decades of experience as a pilot and flight instructor.
The investigation into the exact cause of the crash is ongoing.
