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) N78CA, PA-31-T, was flying from scottsbluff, NE to bloomington, in at 27,000 feet in IMC. The outside air temperature was -33 degrees centrigrade with ice crystals. The pilot had the windshield heat on. With no prior warning the pilot saw a blue/white flash and the lower right hand corner of the co-pilot's windshield cracked. The pilot requested lower altitude to equalize the pressure. When the windshield started to show signs of separating at the crack, he declared an emergency and diverted to Omaha, NE. Maintenance made a temporary repair, and the aircraft was ferried to its maintenance base for replacement of the windshield. The windshield showed no evidence of discoloration or crazing.
