A review of Boeing's (NYSE:BA) 737 MAX jets by the Federal Aviation Administration has expanded to include emergency procedures used by pilots on earlier 737 models, further delaying the jet's return to service, WSJ reports.
"They've lost the confidence of the global aviation organizations across the world", former NTSB Chair James Hall told FOX Business' Liz Claman on Thursday. (UAL.O) removed Boeing Co.'s 737 Max from its schedule through August 3, adopting a similar time table to that of the two other USA airlines that operate the grounded jetliner.
Elwell said the return of the 737 MAX would be determined by what the FAA found in its analysis of Boeing's submission, adding that it was "pretty confident that the application is in good shape".
"It takes as long as it takes to be right", said Dan Elwell at an aviation summit in Fort Worth, Texas.
It comes in a week when Boeing is taking it's software fix to a meeting of 33 aviation regulatory bodies in Dallas. That submission will be followed by test flights to demonstrate the changes to FAA experts.
Elwell reiterated comments from earlier in the week that the FAA has no timetable for recertifying the plane.
Mr Elwell said: "We're going to make sure that when the 737 Max flies again, that the Mcas system and the inputs that make the Mcas system activate are refined in a way that makes the aircraft as safe as possible".
However, in a recent statement, Southwest CEO Gary Kelly said that the company does not have a confirmed timeline for the 737 Max's return to service.
Boeing said it has completed a software fix for a flight control system linked to both crashes.

Shares of the world's biggest planemaker have fallen almost 15% since the fatal crash of an Ethiopian Airlines 737 MAX jet in March, erasing about $40 billion in market value. "But they just need to know there isn't a timetable for bringing the 737 MAX back to flight". The decision was made after the crash of Ethiopian Airlines Flight 302, which killed all 157 passengers on board.
The FAA is still asking Boeing questions about a proposed software upgrade and training revisions and has not decided whether to require simulator training.
"The losses also include maintenance fee and leasing cost during the grounding period ... and it has created clear financial impact for the airlines", an industry insider said.
