From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) While enroute to the Bahamas, at cruiseing altitude, the flight crew noticed a loss of all hydraulic fluid. The PIC declared an emergency and diverted to Palm Beach International and landed the aircraft safely. Mobile aircraft services performed maintenance on the aircraft and determined that the hydraulic pressure hose, at the number 2 engine had ruptured. The pressure hose as well as the hydraulic pumps and filters were replaced and SDR was submitted. As a follow up to the investigation, I was informed by mobile aircraft services that the aircraft departed Florida enroute to conneticut and the problem reoccurred again. The aircraft landed safely in conneticut and was taxied to the bombadier maintenance facility to troubleshoot the problem. It was determined that the rupture of the hydraulic pressure hose which resulted in loss of hydraulic fluid was caused by a blocked pressure regulator. Recommending a letter of warning in the form of a snaap be issued to mobile aircraft services for performing improper maintenance by not inspecting the pressure regulator which is part of the hydraulic system.
