Boeing says 737 MAX expected to resume flying in January
BOEING on Monday said it expects the 737 MAX airplane, which was grounded after two crashes killed 346 people, to resume flying in January, delaying its return by one month.
In a statement, the group said it still hopes to receive certification next month from the US Federal Aviation Administration (FAA), allowing it to resume MAX deliveries to airline customers before the end of the year.
"In parallel, we are working towards final validation of the updated training requirements, which must occur before the MAX returns to commercial service, and which we now expect to begin in January," Boeing said.
It had previously planned for the model to resume flying in December.
The new timetable was well-received by the market, with Boeing shares increasing 4.7 per cent by around 2:30pm (1930 GMT) on the New York Stock Exchange.
The 737 MAX planes have been grounded globally since mid-March, following the deadly Lion Air crash of October 2018 and the Ethiopian Airlines crash in March this year.
The grounding has dragged on far beyond initial expectations as Boeing had to upgrade systems and faced questions from regulators and politicians over the plane.
Southwest Airlines and American Airlines on Friday pushed back their timeframe again for resuming flights on the 737 MAX until early March. Southwest, the largest MAX customer at the time of the grounding with 34 of the aircraft, is currently doing without 175 flights per day out of a total of up to 4,000 while the planes are out of commission.
Companies also need to take into account the time needed to train pilots and install modified software on the aircraft before they can re-enter regular service.
Boeing said on Monday it has completed the first of five milestones it must meet before returning the MAX to service: a multi-day simulator evaluation with the FAA to "ensure the overall software system performs its intended function."
The group said it still needs to run a separate, multi-day simulator session with airline pilots to "assess human factors and crew workload under various test conditions", before FAA pilots conduct a certification flight of the final updated software.
Boeing has notably changed the aircraft's Maneuvering Characteristics Augmentation System (MCAS), an anti-stall mechanism that pilots in both fatal crashes had struggled to control as the jets careered downwards. Boeing will then submit to the FAA all the necessary materials to support software certification.
The final key step before the resumption of commercial flights is an evaluation by a multi-regulatory body to validate training requirements. After this, Boeing said, a report will be released for a public comment period, followed by final approval of the training. AFP
