A private aviation expert has warned that ice accumulation may have crippled the Learjet 60 that crashed in South Florida, killing all nine people on board.
Justin Crabbe, CEO of Jettly and BlackJet, said that the pilot’s final transmissions point to weather conditions that could have destroyed the aircraft’s ability to fly. The jet, bound for the Bahamas from Austin, Texas, fell 35,000 feet in just 76 seconds before slamming into a Palm Beach County roadway like a missile on Sunday afternoon, November 1.
Air traffic control audio captured someone in the cockpit reporting “moderate turbulence” and stating the crew was “managing the ice” shortly before the crash. The plane had departed Austin-Bergstrom International Airport and was headed to North Eleuthera Airport when it went down near Cresthaven around 12:50 p.m. Local time.
“Ice accumulation can reduce lift, increase drag and raise the aircraft’s stall speed,” Crabbe said. “If the aircraft was struggling to maintain airspeed or altitude, the situation could have deteriorated very quickly.”
The 20-year-old co-pilot, Nathalia Gadelha Filgueiras, was among the nine confirmed dead. The Federal Aviation Administration released a statement confirming the crash details and announcing that the National Transportation Safety Board has taken charge of the investigation.
An account on X, @elteslaengineer, has produced a 4D reconstruction of the final three minutes using ADS-B tracking data, ATC audio, NEXRAD weather analysis and dashcam footage. The user wrote: “The Learjet 60 that crashed in Palm Beach County today went from 35,000 ft to the ground in 76 seconds.”
“I rebuilt the last 3 minutes in 4D from ADS-B, ATC audio, a NEXRAD analysis and dashcam video, then ran the engineering. Here’s what the data says, and what it doesn’t,” the user continued.
Crabbe cautioned that definitive conclusions remain impossible without complete evidence. “However, without the complete cockpit audio, flight data and other evidence, it’s difficult to say exactly what happened or whether icing was ultimately responsible,” he added.
The CEO also addressed questions about the crash scene, where little recognizable wreckage remained visible. “A high-energy impact like that can break an aircraft into very small pieces, with much of the wreckage concentrated around the impact point rather than scattered over a large area,” he explained. “Some debris may also be buried beneath the surface or removed by emergency crews. A relatively small debris field doesn’t necessarily mean anything unusual happened before impact.”
Crabbe outlined the full scope of the NTSB investigation ahead. Investigators will reconstruct the final flight path, examining altitude, airspeed, descent rate and any unusual changes in direction or attitude. They will also review cockpit recordings, radar and ADS-B data, weather reports, icing evidence, maintenance history, anti-icing equipment, engine performance and physical wreckage for mechanical issues.
The FAA confirmed all nine people on board died in the residential area crash, with no survivors among those traveling from Texas toward the Bahamas.
