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) Event summary - at approximately 1612 greenwich mean time (gmt), while climbing through 24,000 feet, the flight crew observed a message for the green hydraulic system low reservoir level, indicating a loss of green system fluid. As an action in the flight manual irregular procedure, the first officer attempted to turn off the power transfer unit (ptu), however, the ptu would not shut off. The first officer contacted samc who instructed him to cycle the circuit breaker for the ptu. This had no affect and the ptu continued to run until the yellow hydraulic system overheated. The flight crew turned off the yellow system, which now forced them to rely solely on the blue hydraulic system which required them to land as-soon-as-possible. The flight crew attempted to lower the flaps after letting the yellow system cool down; however, the flaps locked out before fully deploying. The landing gear was extended manually and the auxiliary power unit (APU) was started on short final. The aircraft landed without incident at kpit.
