Boeing completes update of 737 Max software cited in deadly crashes

But Boeing's announcement - which lifted shares of the embattled company - comes only a week before the US Federal Aviation Administration is set to brief its global peers among civil aviation regulators on its process for allowing the planes to fly again. That flight has not yet been scheduled.

After the fatal crashes in Indonesia last October and in Ethiopia this March, investigators tentatively concluded that the MCAS system repeatedly forced both planes into nose dives, due to spurious data that the system was receiving from a single angle-of-attack sensor mounted on each plane's exterior.

"If the authorities there don't certify the 737 Max, they'll have to avoid that airspace". If the jets are not cleared to fly by then, the airlines will be forced to again cancel more than 100 daily flights. Boeing has disclosed an initial financial hit of $1 billion United States to fix the plane, and new Max jets are parked at its Seattle-area factory and elsewhere because deliveries have stopped.

According to an audio recording of the meeting that was provided by the Allied Pilots Association (APA), the airline's pilot union, when the American pilots pressed Sinnett for faster action, he laid out a six-week timeline to develop the fix, followed by a 90-day period for the FAA to review and mandate its implementation.

The software update is created to disengage MCAS if readings from the two angle-of-attack sensors substantially disagree, and it also sets tighter limits on the automatic controls.

"With safety as our clear priority, we have completed all of the engineering test flights for the software update", Boeing chairman, CEO and president Dennis Muilenburg said in a statement Thursday.

The airline said the suspension of flights involving Boeing 737 MAX 8 planes operated by SilkAir, and issues with Rolls-Royce engines that power its 787 Dreamliner fleet, had hit passenger capacity.

Boeing developed the Max early this decade to compete with a jet from its European rival Airbus that was winning over airline customers with its better fuel efficiency. The bottom line is that Boeing says it's ready for that scrutiny and is eager to get the 737 MAX back to the skies.

The 737 Max was grounded after an Ethiopian Airlines crash in March killed all 157 on board.

Earlier this month in a major endorsement for the changes made by Boeing to the 737 MAX, the world's largest pilots' union said it will not ask the U.S. regulator the FAA to require additional mandatory simulator training on the Maneuvering Characteristics Augmentation System (MCAS) scenarios before pilots can fly the aircraft again.

The Ethiopian Airlines crash happened in the interim. "That's the reason that we had this crash".

Major US airlines have reported sluggish revenue growth due to massive flight cancelations during the first quarter.

Boeing is giving FAA additional information on how pilots interact with the airplane controls and displays in different flight scenarios.

It will also make the system less potent, which is expected to prevent the steep dives seen in the two crashes, and provide additional training materials, it said. Criminal prosecutors, congressional staffers, and the Transportation Department inspector general are reviewing the initial certification of the 737 and the FAA's processes.

Some foreign regulators and safety experts say pilots should practice responding to the new software in flight simulators - a requirement that would delay the plane's return by weeks or months.
