Boeing rolls out software fix to defend 737 MAX franchise

Boeing on Wednesday took its moves to defend its core 737 airliner franchise, saying it had developed software fixes to prevent failures of an automated flight control system that is being scrutinized after two deadly crashes in the past five months.

Boeing, in the midst of one its worst crises in years, is under pressure from crash victims' families, airlines, lawmakers in Washington and regulators around the world to prove that the automated flight control systems aboard its 737 MAX aircraft are safe, and that pilots have the training required to override the system in an emergency.

A Boeing official in Seattle said on Wednesday the timing of the software upgrade was “100 percent independent of the timing of the Ethiopian accident,” and the company was taking steps to make the anti-stall system “more robust.”

There was no need to overhaul Boeing's regulatory relationship with the U.S. Federal Aviation Administration (FAA) now, the company said.

"We are going to do everything that we can do to ensure that accidents like these never happen again," Mike Sinnett, Vice President for Product Strategy and Future Airplane Development told reporters.

The FAA said it had not reviewed or certified the software upgrade yet.

U.S. Transportation Secretary Elaine Chao and some lawmakers on Wednesday questioned why Boeing did not require safety features on its top-selling plane that might have prevented the crashes.

"It is very questionable if these were safety-oriented additions, why they were not part of the required template of measures that should go into an airplane," she said, adding she was not ready to require that all safety options be retrofitted on the existing airplane.

Executives with U.S. airlines welcomed Boeing's moves, but want U.S. regulators to sign off on the upgrade.

Southwest Airlines Co, which on Wednesday became the first major airline to formally cut its financial outlook for the year after being forced to pull its MAX fleet of 34 jets out of service, supported Boeing's decision.

"Boeing's software update appears to add yet another layer of safety to the operation of the MAX aircraft," Southwest's certificate chief pilot Bob Waltz said.

Allied Pilots Association, which represents American Airlines Group Inc pilots, said it was pleased with Boeing's progress but warned the certification process should not be rushed. The fix should be fully vetted and take into account any further information from an investigation into an Ethiopian Airlines crash on March 10, the association said in a statement.

Airline stocks turned positive after Boeing unveiled the software fix. CFRA analyst Jim Corridore, who has a “buy” rating on Boeing, said news from the company and the Washington hearing were positive steps toward getting the MAX jets airborne again.
