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.
The aircraft was cruising at FL400 when it encountered turbulence and higher than standard air temperature resulting in a loss of airspeed that required an immediate descent. The pilot informed ATC which issued a vector (20 degrees right) and clearance to a lower altitude to avoid conflict with other traffic. Closest loss of separation: 3.67NM/200FT.
