Aviation around the world changed as a result of the fatal accident involving Air Canada Flight 797. The investigation led to massive changes to the materials inside the cabins of commercial aircraft.

On June 2, 1983, the DC9-32 on a routine flight from Dallas to Toronto had an inflight smoke event that led to an emergency landing in Cincinnati. As the passengers and crew began evacuating the aircraft, a flash fire in the cabin created heat and toxic smoke that killed 23 of the 46 occupants.

The NTSB investigation revealed that the fire caused the release of dangerous levels of toxic chemicals and gases from the materials used inside the cabin. This finding led to a systematic transition to new fire-blocking materials. John Goglia shares his role in replacing materials on aircraft he maintained.

This accident also led to the requirement for smoke detectors in lavatories. It also led to the use of air-driven flush motors in lavatories, rather than electrical flush motors.
