The National Transportation Safety Board released its preliminary report Friday, July 24, into the July 13 plane crash that killed three members of a Toms River family, a tragedy that has weighed heavily on the Ocean County community in the days since. The report’s release comes on the same day the family is holding funeral services, keeping a devastating loss that occurred nearly two weeks ago freshly present in the minds of a tight-knit Jersey Shore community still grieving together.
The crash claimed the lives of Dr. Gabriele P. Jasper, 70, of Toms River, his daughter Gabriella M. Hillgrube, 33, of Forked River, and his two-year-old granddaughter Giuliana M. Hillgrube. Dr. Jasper, a widely respected pain management physician who founded the Jasper Spine Institute in Brick, had been flying his family home to Monmouth Executive Airport in Belmar after picking them up in upstate New York, a routine trip that ended in tragedy just moments after departure.
According to the NTSB’s preliminary findings, the twin-engine 1976 Piper Smith Aerostar 601P never gained sufficient altitude after leaving the runway at Adirondack Regional Airport for standard FAA flight tracking equipment to capture data on the flight. In the absence of that standard tracking, investigators reconstructed the aircraft’s brief flight using footage from local commercial security cameras. That reconstruction shows the plane departing at 10:35 p.m., reaching a point roughly one mile from the runway just 46 seconds later. During that short window, the aircraft initially climbed to 125 feet before descending to 75 feet, leveling off for approximately 12 seconds while its speed fluctuated between 151 and 169 knots before the aircraft went down.
A nearby home security system near the remote, wooded crash site off Route 186 captured audio of the plane’s engine at 10:36 p.m., followed by the sound of the crash itself. First responders searched the dense Adirondack terrain for approximately four hours before locating the wreckage at 2:30 a.m. A fire following the crash consumed much of the aircraft, complicating the recovery effort during those difficult overnight hours.
The NTSB’s report notes that Dr. Jasper was a genuinely experienced pilot, holding multiple advanced flight certifications and more than 1,000 recorded flight hours, including substantial experience flying at night. The aircraft had also completed its mandatory annual inspection without any noted issues on February 2, details that leave investigators with a genuinely complex picture to untangle regarding exactly what caused the aircraft to lose altitude so quickly after takeoff.
Federal investigators have retained the wreckage for further examination, and audio recovered from local security cameras has been sent to the NTSB’s Vehicle Recorders Laboratory for detailed sound spectrum analysis, a process specifically aimed at identifying any signs of mechanical or engine failure in the moments before the crash. A final report establishing the official probable cause is expected to take 12 to 24 months to complete, meaning the Jasper and Hillgrube families, along with the broader community mourning alongside them, will likely wait well over a year for full, definitive answers about what happened in those final 46 seconds.
For now, the Ocean County community is focused on honoring three generations of a single family lost together, a tragedy that has touched Toms River and Forked River deeply in the two weeks since the crash, and one that today’s funeral services bring back into painful, immediate focus even as the broader investigation into its cause continues.
