A 2025 UPS cargo jet crash in Louisville, caused by a left engine fire from a fuel line rupture, killed both pilots and raised concerns about Boeing 767 safety.

The NTSB has revised its investigation into the November 2025 UPS cargo jet crash near Louisville, confirming that both pilots were killed when the aircraft lost control due to a left engine fire brought on by a fuel line rupture. Previous engine problems with the aircraft raised questions about maintenance and inspection procedures. The crash is the second deadly Boeing 767 incident in less than a year, raising questions about the aircraft's dependability and Boeing's safety procedures. The NTSB is investigating engine design, maintenance records, and fire suppression systems, but it has not yet identified a primary cause. In light of persistent industry-wide safety concerns, the findings may lead to regulatory changes and additional pressure on Boeing.
