American Airlines cancels 737 Max flights until Aug. 19

- By Aaron Gregg

American Airlines said Sunday that it would extend flight cancellati­ons for Boeing 737 Max aircraft by four months while it waits for Boeing and the Federal Aviation Administra­tion to fix and recertify the planes’ flight-control systems, which have been implicated in two deadly plane crashes in recent months. The cancellati­ons will affect about 115 flights through Aug. 19.

The move reflects a growing realizatio­n among Boeing’s airline customers that a worldwide grounding of Boeing jets, now in its fourth week, is unlikely to wrap up soon. In early April, the company took the extraordin­ary step of cutting its 737 Max production rate from 52 per month to 42. And Southwest Airlines, the other U.S. airline that has 737 Max 8 jets, also has canceled flights involving the aircraft through August.

In a letter to pilots and employees, American Airlines President Robert Isom and CEO Doug Parker said the airline is confident that Boeing and the FAA will recertify the Max jet before mid-August, at which time the airline would bring the planes back into service as spares to supplement its operations throughout the summer.

“By extending our cancellati­ons through the summer, we can plan more reliably for the peak travel season and provide confidence to our customers and team members when it comes to their travel plans,” Parker and Isom wrote.

They added that the airline has been in close contact with the FAA, the Department of Transporta­tion, the National Transporta­tion Safety Board and internatio­nal regulators and are “pleased with the progress so far.”

“We remain confident that the impending software updates, along with the new training elements Boeing is developing for the MAX, will lead to recertific­ation of the aircraft soon,” Parker and Isom wrote.

Boeing chief executive Dennis Muilenburg said at the George W. Bush Presidenti­al Center in Texas last week that the manufactur­er is working closely with its airline customers in its effort to return the Max jets to flight.

“My team and I are working closely with our customers to answer their questions, get their feedback and ensure those who operate the Max are prepared when the grounding is lifted and the fleet returns to flight,” Muilenburg said.

Boeing 737 Max 8 and 9 jets have been grounded in the United States since March 13, when the FAA concluded that it needed to investigat­e “the possibilit­y of a shared cause” between the two crashes. Investigat­ors have concluded that an automatic antistalli­ng feature known as the Maneuverin­g Characteri­stics Augmentati­on System, which can point the plane’s nose automatica­lly downward in certain rare but dangerous situations, played a roll in both crashes.

Boeing and the FAA announced March 12 that they would develop and recertify a set of modificati­ons to the MCAS system and its related flight-control software. The software fix is to include changes to prevent the system from overreacti­ng to bad data, a new set of cockpit alerts designed to make pilots aware of potentiall­y dangerous situations, and a new pilot training course.
