FAA Issues Safety Warning on Sensor Linked to 737 Max Crashes

- FAA action is ‘reminder’ and not linked to new findings

U.S. aviation regulators are urging workers at airports to take extra care around the sensors on the sides of aircraft that failed in two crashes of Boeing Co. 737 Max jets since October.
So-called angle-of-attack vanes, which measure whether a plane’s nose is pointed too high relative to oncoming air to prevent dangerous aerodynamic stalls, are vulnerable to damage, the Federal Aviation Administration said in a notice.
