FAA Revises Airworthiness Directive for EMBRAER Airplanes to Prevent TAT Sensor Failure

Summary

The Federal Aviation Administration (FAA) is revising an earlier notice of proposed rulemaking (NPRM) for an airworthiness directive (AD) that applies to certain EMBRAER airplane models, including the EMB-135BJ, -135ER, and -145 series, to prevent failure of the total air temperature (TAT) sensor heating system, which could lead to insufficient thrust during takeoff.
