Boeing Co. has discovered a new software problem on the grounded 737 Max, but the company said the flaw won\u2019t set back the goal of returning the plane to service in mid-2020.<\/p>\n
The planemaker identified the issue during flight testing and notified the Federal Aviation Administration last month, according to an email Thursday from Boeing. The problem was that an indicator light, designed to warn of a malfunction by a system that helps raise and lower the plane\u2019s nose, was turning on when it wasn\u2019t supposed to, the company said.<\/p>\n
\u201cWe are incorporating a change to the 737 Max software prior to the fleet returning to service to ensure that this indicator light only illuminates as intended,\u201d the company said.<\/p>\n
The new software problem complicates Boeing\u2019s efforts to return the Max to service by mid-2020, even if it doesn\u2019t derail the recently extended timetable. FAA chief Steve Dickson, told reporters in London that a certification flight for the grounded jet could occur in the next few weeks — a key regulatory step in allowing the aircraft to start flying passengers again.<\/p>\n
Dickson said the FAA is evaluating the latest software issue.<\/p>\n
The stabilizer trim warning light \u201chad been staying on for longer than a desired period,\u201c he said without providing more detail.<\/p>\n
Boeing shares seesawed during Dickson\u2019s remarks. They rose after Dickson\u2019s comments on the timing of the certification flight, then pared gains following the disclosure by Bloomberg News of the new software problem. The stock then recovered, climbing 3.6% to $341.41 at 1:55 p.m. in New York — the most on the Dow Jones Industrial Average.<\/p>\n
Aviation regulators are closely aligned on design requirements for the Max, but may differ country-by-country on when the jet returns, Dickson said.<\/p>\n
The divergence is likely even though authorities agree more than they disagree on the measures needed for Boeing\u2019s best-selling plane to resume flying after two fatal crashes, Dickson said.<\/p>\n
The FAA has retained a strong working relationship with the European Union Aviation Safety Agency and other regulators during the Max crisis, Dickson said. The debacle has spurred questions about whether the FAA\u2019s oversight was too lax when it approved the plane\u2019s software design, which has been linked to both crashes.<\/p>\n
The U.S agency will consult with other regulators on how to handle future approvals for enhancements to existing aircraft under the so-called changed-product rule, Dickson said. Updating an existing model, such as the 737, currently can be done without extensive scrutiny of aspects that don\u2019t change. But following the crashes, critics have said regulators should conduct more thorough reviews.<\/p>\n
Any shift could affect certification of 777X, a re-engined, re-winged update of Boeing\u2019s twin-aisle plane. The 777X, which has folding wing tips, took its first flight last month and is expected to debut commercially next year.<\/p>\n
Asked about a likely date for a return to service for the Max, Dickson said it isn\u2019t helpful to talk about timelines. Boeing needs to concentrate on making complete, quality submissions on its fixes for the plane, he said.<\/p>\n
The former Delta Air Lines Inc. pilot reiterated that he plans to fly the Max himself before it returns to the skies.<\/p>\n
The FAA may need to expand its budget to improve its capabilities to assess aircraft designs in the wake of missing safety issues on the Max, Dickson said. But he said the agency doesn\u2019t need much to enhance its existing resources.<\/p>\n
The new software issue on the Max resulted from Boeing\u2019s redesign of the two flight computers that control the 737 Max to make them more resilient to failure, according to people familiar with the matter.<\/p>\n
The problem involves an alert designed to warn when the so-called trim system, which helps raise and lower the plane\u2019s nose, isn\u2019t working properly, said the people, who asked not be named because they weren\u2019t authorized to comment on it.<\/p>\n
One of the people confirmed Boeing\u2019s assessment that the new flaw isn\u2019t likely to change the plane\u2019s projected return to service because the company had built padding into its schedule.<\/p>\n
Boeing last month announced it doesn\u2019t expect the plane to fly again until the middle of the year. After months of missed deadlines and growing tension with the FAA, the Chicago-based company said it was estimating a timeline that included extra room in case new issues arose.<\/p>\n
Separately, the manufacturer was already at work on a software system called the Maneuvering Characteristics Augmentation System. The MCAS system was involved in the two fatal crashes, which killed 346 people and led to the grounding on March 13.<\/p>\n
