NTSB narrative
The pilot-in-command stated that while passing through 35,000 feet mean sea level, the flightcrew heard a sound similar to a compressor stall, followed by a loss of power to the right engine. He immediately declared an emergency with air traffic control and initiated the checklist items for engine shutdown in-flight. Shortly thereafter, the cabin service representative informed him that the No. 4 outer window pane on the right side of the airplane had separated. The flightcrew made a visual approach back to the departure airport and landed without further incident.
A bore scope examination of the engine revealed that it had experienced a compressor stall and flamed out as a result of debris from the No. 4 outer window pane being ingested into the engine. Review of the airplane logbooks revealed that all required inspections had been conducted on the window and no anomalies were noted. Further examination of the window revealed fractures in the outer pane, which originated from an area of preexisting progressive cracking, emanating from the exterior surface of the window. The initial cause of the cracking could not be determined.
Probable cause
Progressive cracking from an undetermined initiation source, which resulted in the failure of the No. 4 cabin window outer pane, and the subsequent foreign object ingestion to the right engine.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
