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.

3/22/11- Approximately 30 minutes after departure from slc they received "rt hyd low press" message. Complied with checklist decided to divert to lgb for Gulfstream mx. 30 minutes out of lgb received left hyd system failure warning message, crew declared an emergency and landed without further incident. When crew attempted to activate aux hyd system for landing, it also failed.3/24/11- work order from Gulfstream Long Beach #1211-001266 on 3/28/11. It appears the r/h hyd shut off valve never fully reopened after the fire warning check during preflt. This lead to cavitation of the hyd system to the r/h engine driven pump, which caused it's failure. Eventually low pressure resulted in the failure of the left hyd pump.
