FAA Adopts Rule Requiring Checks on Embraer Pitch Trim Actuators

The Federal Aviation Administration has published a final rule requiring owners and operators of Embraer EMB-545 and EMB-550 airplanes to check the pitch trim actuator on the horizontal stabilizer. The rule adopts technical instructions from Brazil’s aviation authority to address reports of failures in this component. If the check fails, the actuator must be replaced, and the results must be reported.

Why it matters: The pitch trim actuator controls the airplane’s pitch. The FAA says failures in one load path could lead to total failure, potentially allowing the horizontal stabilizer to move uncontrollably under aerodynamic loads. This rule forces a check to catch failures before they cause a loss of control.

Who it affects

• Owners and operators of Embraer EMB-545 and EMB-550 airplanes registered in the U.S.
