NTSB Finds Learjet Tail Debris After Fatal Florida Crash

Federal investigators are examining a catastrophic Learjet 60 crash near Greenacres, Florida, after recovering aircraft tail fragments several miles from the impact site. All nine people aboard, including Austin technology entrepreneur Adam Robinson, his wife and their two children, died when the private jet plunged from approximately 35,000 feet on November 1, 2026.

National Transportation Safety Board (NTSB) member Tom Chapman confirmed on November 3 that investigators recovered sections of the aircraft's horizontal tail assembly in three pieces, between approximately 1.3 and 3.8 miles from the crash site. The discovery indicates that important aircraft components separated before impact.

The aircraft was traveling from Austin-Bergstrom International Airport to North Eleuthera in the Bahamas. Flight tracking and air traffic control recordings show that the jet experienced icing and turbulence before entering an extremely rapid descent over Palm Beach County.

According to the NTSB, investigators are examining whether the aircraft's structural breakup caused the loss of control or occurred during the final descent. A preliminary report is expected in approximately one month, although determining the definitive cause could take more than a year.

Chapman explained that the recovered components could help investigators reconstruct the aircraft and establish the sequence of events leading to the disaster.

He also warned residents against handling possible aircraft debris, asking anyone who discovers fragments to leave them untouched and contact the NTSB or local authorities.

Among the nine victims were Adam Robinson, 45, his wife Helen Sharp, 40, and their children Emma, 4, and Charlie, 2. Family friends Rachael Reed and Charmi Fehr, nanny Anita Maria Cetina, and both pilots also died.

The aircraft's captain was identified as Jeff Gregory, 55, by his employer, East Coast Jets, a charter aviation company based in Allentown, Pennsylvania. The copilot was identified as Nathalia Gadelha Filgueiras, 20, from Boca Raton, Florida.

The Robinson family had been traveling to the Bahamas when the accident occurred. Their relatives released a joint statement remembering the couple and their children.

"Adam and Helen were devoted parents, and Emma, 4, and Charlie, 2, were the light of their lives. Helen and Adam were the love affair that will last forever. Their warmth, generosity and gift for making people feel welcome touched so many lives. Their loss will be felt deeply by all those who loved them and who they loved in return," the families said.

Robinson was CEO and co-founder of Retention.com, an Austin-based technology company specializing in identifying website visitors for business marketing. He also led RB2B and MoltSets, two other business ventures.

On the day of the crash, Robinson announced that RB2B had reached $10 million in annual recurring revenue with a single full-time employee. He also reported that MoltSets was approaching $1 million in annual recurring revenue.

"RB2B is $10m ARR with 1 FTE," Robinson wrote. "MoltSets is almost $1m ARR."

Two months earlier, he had reported $9.5 million in annual recurring revenue for RB2B and described the $10 million milestone with a small team as "the promised land."

His final LinkedIn post also discussed a disagreement with friend Jesse Ouellette about whether RB2B and MoltSets should remain separate businesses or merge their operations.

"My question: WHY DO I NEED TO DO EITHER OF THOSE THINGS?" Robinson wrote. "Honestly, I'd be thrilled if RB2B never grew another dollar," he added.

The pair had planned to discuss their competing positions during a live Tuesday broadcast called "Claude Did What!!??" Robinson announced the upcoming discussion in his final post.

"So we're settling it LIVE," he wrote. "There's much more to his argument, but I'm saving it for Tuesday. Grab some popcorn and pick a side."

Retention.com, RB2B and MoltSets also released a statement honoring their founder and colleague.

"a friend, a mentor and a bold, outspoken leader who lived life to the fullest," the companies said, describing Robinson's contribution to their organizations.

"He cared deeply about the people around him and brought energy and conviction to everything he built. His loss is deeply felt across our team and the tech community, as we collectively mourn this significant loss," the companies added.

Separately, NASA Administrator Jared Isaacman defended Filgueiras against online criticism following the release of cockpit communications. He urged the public to avoid assigning blame before investigators establish what happened.

Isaacman, an experienced jet pilot and commercial astronaut with more than 8,000 flight hours, said speculation about the young copilot was premature.

"Let people investigate, learn, and share the facts. Be respectful to those who perished and the families who carry their memories. God bless them and their loved ones," Isaacman wrote on X.

He explained that his comments reflected personal experience with charter aviation and more than two decades of flying similar aircraft.

"Writing this in my personal capacity, but I have been flying these types of aircraft for more than 20 years, with over 8,000 hours, and have reasonable familiarity with how the charter world operates. I feel compelled to post after seeing commentary about the Lear 60 crash, from missile strikes to DEI to critiquing this poor woman's final radio calls," Isaacman wrote.

Isaacman also emphasized that the copilot continued communicating with air traffic controllers during the emergency.

"She likely knew before many of those calls that she was going to die," he wrote.

He cautioned against drawing conclusions without access to the aircraft's maintenance records, structural condition and cockpit circumstances.

"I understand the public interest given the footage and audio. But you do not know the aircraft's maintenance history, whether there was a structural failure, if any failure was induced by turbulence, overspeed, or overcontrol, or everything happening in that cockpit," Isaacman wrote.

According to Isaacman, charter operators commonly employ relatively inexperienced commercial pilots who have completed the applicable Federal Aviation Administration training, qualifications and required checks.

The aircraft departed Austin at approximately 10:37 a.m. Eastern Time on November 1 with seven passengers and two crew members. Radio recordings indicate that the crew encountered icing and moderate turbulence while flying at approximately 35,000 feet.

The copilot reported that the aircraft was experiencing manageable icing and turbulence before requesting permission to climb to 37,000 feet. Air traffic controllers approved the request at approximately 12:48 p.m. Eastern Time.

Within seconds, the crew reported an emergency as the aircraft began descending rapidly. The recorded descent rate increased from 8,000 feet per minute to 10,000 feet per minute before reaching approximately 20,000 feet per minute.

During the final communications, Filgueiras warned controllers about the aircraft's condition.

"We have light, clear ice that is manageable and moderate turbulence," she radioed, according to recordings published by LiveATC.

As the situation deteriorated, she declared an emergency and reported the accelerating descent.

"Mayday, mayday!" Filgueiras transmitted. "We're descending 10,000 feet per minute!"

She subsequently reported the aircraft's extreme descent rate.

"We are in an overspeed condition descending 20,000 feet per minute," she said.

The final moments were captured in the air traffic control recordings.

"We're going to crash into the ground!" Filgueiras told controllers.

The pilot's final transmission came seconds before impact.

"We're out of time," the pilot said.

Flight tracking data indicated that the aircraft lost more than 27,000 feet in approximately one minute before the tracking signal disappeared. The jet struck Military Trail near Cresthaven Boulevard and 10th Avenue North, creating a large crater and triggering a fireball.

Nearby residents described hearing an explosion and losing electrical power. One resident, Andrew Mannino, described the immediate aftermath.

"I heard and felt the boom. The power immediately went out," Mannino said.

Scattered thunderstorms and heavy rainfall were present in the region. The crew's reports of ice accumulation and turbulence have made weather conditions an important part of the federal investigation.

The NTSB is also examining the aircraft's maintenance history, structural integrity and flight conditions. Authorities reported that one person on the ground sustained a leg injury.
