On this week’s episode of AvTalk, a confidential report hypothesizes cigarettes and leaking oxygen brought down EgyptAir flight 804, French investigators provide an update on Air France flight 11, and Boeing releases its first quarter earnings and guidance on its aircraft programs.

Cigarettes and Oxygen don’t mix

In May 2016, EgyptAir flight 804 crashed into the Mediterranean Sea en route from Paris to Cairo. Preliminary findings, based on evidence retrieved from the black boxes and analyzed by the French BEA, indicated the presence of fire onboard the aircraft. The Egyptian government subsequently declared that explosive residue had been found and turned the investigation over to judicial authorities. Now a confidential report developed by French experts and obtained by Italian newspaper Corriere Della Sera indicates the most likely cause of the crash was a fire initiated by one of the pilots smoking near a leaking emergency oxygen mask.
