Certification flights for Max may be in October

Certification flights for the Boeing 737 Max are likely to be conducted in October following approval of the software update to the plane's anti-stall device implicated in two fatal crashes, according to news reports.

But the US Federal Aviation Administration, or FAA, said there is no schedule to return Max jets to service and declined to comment on the news reports.

"The certification flights are part of the return to service, so we aren't going to speculate on when they will occur," Lynn Lunsford, a spokeswoman for the FAA, told China Daily.
