The Federal Aviation Administration has discovered a brand new drawback in Boeing’s troubled 737 Max that the company should tackle before the regulatory agency will permit the airplanes to fly passengers again. The invention further delays the aircraft’s return to service.
Southwest,United and American Airlines, the three U.S. carriers that fly Max jets, have already pulled the plane from their schedules through Labor Day weekend and this newest development might set back the aircraft’s return to business flight well into autumn.
Boeing’s well-liked slender-body aircraft has been grounded since March after an Ethiopian Airlines 737 Max crashed shortly after taking off from the airport, killing 157 people on board. It was the second crash of a Max aircraft in five months; as a Lion Air jet crashed in Indonesia last October, killing 189 people.
Investigators link both crashes, partially, to an automatic flight control system that acted on faulty data from malfunctioning sensors and put the planes into nose dives the pilots couldn’t pull the planes out of.
Boeing has developed a software program repair for that flight control system, referred to as MCAS, however sources acquainted with the situation inform NPR that in simulator testing final week, that FAA test pilots found a separate problem that affected their capability to quickly and easily follow recovery procedures for runaway stabilizer trim and stabilize the plane.
A press release from the regulatory company says as a part of a process designed to find and highlight potential dangers, “the FAA discovered a possible threat that Boeing must mitigate.”
