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.

02/04/2026 During a flight from Memphis to baton rouge at cruise altitude of flight level 360, a crack was noticed in the copilot's side window. The crack progressively worsened, extending towards the nose of the aircraft. The crew decided to return to Memphis. Upon completing the turn, they coordinated with ATC, declared an emergency, and requested a lower altitude to alleviate internal pressure and reduced external speed, thus decreasing pressure on the windshield. The crew then followed the appropriate checklist, which confirmed the actions they had already taken. The aircraft continued to Memphis, where it landed safely and proceeded to the FBO.
